My Youpin Suanglng JC-B18 2.5 litres mini washing machine

Do you remember my portable ultrasonic turbine mini washer that I bought at the price of slightly above RM40 that I used it to wash the mopping cloth of my Roborock S7 robot cleaner?

Unfortunately, I have to tell you that it cannot last long, and started to malfunction after about 3 months of daily usage. Maybe its motor is too weak to handle daily usage, and now it could hardly spin.

It is still a very good mini washer, probably for occasional use, such as when you're travelling.

Anyhow, I have found a more robust replacement for it, which is my Youpin Suanglng JC-B18 2.5 litres mini washing machine, which cost me around RM150.

This mini washing machine has a higher power motor than my previous mini washer, operating at 12V 10W.

It has its own bucket with touch power button. Other than the washing function similar to my previous mini washer, it also has voilet ray and ozone bubbles to sanitize virus and bacteria.

See it in action below:

Note that its bucket is pretty small, at the size of 165mm x 165mm x 187mm only.

Other than mopping cloth, it is also suitable to wash handkerchief, socks, underwear, baby clothes, saliva napkin, and other small items.

Hopefully this Youpin Suanglng JC-B18 mini washing machine can last for 2 years or more.

My Hericaine Twister R-6053 rechargeable portable dry and wet vacuum cleaner

It seems that vacuum cleaners nowadays have become more and more portable, light-weight, and more importantly affordable.

My Hericaine Twister R-6053 rechargeable portable dry and wet vacuum cleaner just cost me slightly above RM50 only, with full set of necessary components, and even with a 30cm x 30cm microfibre mopping cloth as free gift (not in the photo).

I like its carrying bag, which can store all of its components, making it very easy to store and to carry along. Everything in the photo above just has a total weight of less than 1kg.

I use this to vacuum my car, as well as tabletops, cupboards, cabinets, keyboards, desktop rig (outside and inside), printer, screens, corners, air-cond outlets, etc.

It is pretty small in size, and it operates with its own rechargeable battery without any power cord, making it easy to reach out to any place and any corner that you want to vacuum.

Upon full charge, it can operate up to 30 minutes. Its recharging time is quite long though, taking about 3 hours for a full recharge.

It has a pretty decent suction power of 3200kpa, able to suck in items such as paper clips and even small coins without much problem.

I like its wet vacuuming capability, enabling you to suck away spilled water on cushion, for example.

Its HEPA filter is washable and reusable. This HEPA filter is also sold as replacement item at the cost of around RM13.

My Okura 2-in-1 foldable aluminium ladder with clothes drying hanger rack

I believe every household needs a ladder for the purpose of ceiling fan cleaning, replacing faulty light bulbs, air-cond filter cleaning, reaching up to things at higher place, etc.

Your ladder would probably sit in your storeroom most of the time, until the moment you need to use it.

What if you have a ladder that has additional function to use it more often, such as being a clothes drying hanger rack?

The Okura 2-in-1 foldable aluminium ladder with clothes drying hanger rack would be the solution. It can function as a ladder, and it can also function as a clothes hanger rack, although you can't use both functions at the same time.

My 4-steps Okura ladder costs around RM150, slightly more expensive than ordinary ladder without the clothes hanging rack function. There are taller 5-steps and even 6-steps 2-in-1 ladders available in the market, selling at more expensive price.

This 4-steps ladder is good enough for condominium or apartment with not-too-high ceiling height. Its highest step is 96cm (3.15 feet) from the ground. It has a pretty tall and firm handrail for you to hold on. Being a ladder, its loading capacity is 120kg.

As you can see from the photo below, it is just slightly higher than a washing machine.

I find the length of this 4-step ladder just nice for it to be portable and easy to carry. Its weight is just 6kg, about the weight of a baby below 1 year old.

It can fit in ordinary sedan car, probably not in the boot, but with the car's back seats folded.

It is pretty robust and solid. Its handrail is covered with soft rubber, which is very nice to grasp. When you fold it and lean it against the wall, the soft rubber will not hurt the wall.

However, its rack is not able to hang too many clothes. The 5-steps or 6-steps model will have a longer rack to accommodate more clothes.

A use case for this rack is: to make use of the washing machine and clothes dryer for most of your clothes, while using the rack to dry your delicate hand-washed items, such as underwear.

My Geekria 170cm stereo audio cable with noise-cancelling boom mic for my Sony WH-1000XM4 headset

The Sony WH-1000XM4 headset can operate in Bluetooth wireless mode as well as in 3.5mm audio cable wired mode.

The audio cable that comes together with this headset only support audio in but not audio out. As such, I believe the 3.5mm AUX port on the Sony WH-1000XM4 headset also does not have audio out function to transmit your voice collected from its microphone to the connected device when it is operating in wired mode.

The built-in noise-cancelling microphone of the Sony WH-1000XM4 headset actually functioning pretty well. However, just like all other wireless headset without an attached boom mic, the location of its microphones is some distance away from your mouth. Your voice will sound a little bit "backwards" and much softer, compared to the situation of using a headset with a good boom mic. If the voice captured is too soft, it might become unclear to your listening party over the other end of a phone call or conference call.

To solve this issue, you will need another microphone, not belong to the headset, to take care of your audio out (which becomes the audio in of the receiving device, such as your computer or mobile device).

If the operating system allows separate handling of audio in device and audio out device, then you can make use of your headset to receive its audio out, while using a separate microphone to capture its audio in. Microsoft Windows can handle this kind of situation pretty well.

I believe all laptops nowadays come with built-in microphone, so you can make use of that for your audio in. For PC without built-in microphone, you can get a 3rd party microphone for its audio in.

There also exists another kind of solution, which is using an audio cable with a boom mic that can work independently on its own. This kind of solution is easier and more convenient to use, as you don't need to mess around too much with the audio settings of your computer's operating system and/or conferencing software. With this solution, you can turn your headset into a gaming or call-centre headset that can capture your voice loud and clear.

There are several brands available in the market, including V-Moda, Headset Buddy, Audio-Technica, Geekria, etc. I have chosen Geekria mainly because of its price of around RM35 only, and it works well like those more expensive counterparties.

My Geekria stereo audio cable is 1.7 meter long, which is a perfect length that is long enough for your convenience to use, yet not too long for easy storage.

Inside its packaging contains:

  • Reusable storage bag
  • The 1.7 meter audio cable with attached boom mic
  • Y adapter cord (to separate audio in and audio out, when needed)
  • Leather wire organizer strap
  • 2x microphone cap

Its boom mic is attached with an adjustable cord.

If your computer's 3.5mm audio port supports both audio in and audio out, you don't need to use the Y adapter cord, and can just plug it in as shown in the photo below.

If your computer has separate 3.5mm ports for audio in and audio out, you can plug it in by using the Y adapter cord, as shown in the photo below.

This Geekria stereo audio cable with noise-cancelling boom mic is fully compatible with the Sony WH-1000XM4 headset, as well as the earlier versions of WH-1000XM3, WH-1000XM2, and most other models of Sony headset.

With this, your voice will be recorded loud and clear, with unnecessary ambience noise filtered out properly, and with any echoing problem.

Try it out, and you will be able to notice the tremendous difference of using it than using the wireless microphone in the headset.

EPF declared 6.10% (conventional) / 5.65% (shariah) dividend for 2021

After an even longer waiting time than last year, the Employees Provident Fund (EPF, a.k.a. KWSP) has finally declared the dividend rate for financial year 2021.

For year 2021, the dividend declared for conventional account is 6.10% while for Shariah account is 5.65%. The dividend will be credited into members' account soon, and you can check for it by login into your EPF i-Account.

Year 2021 was the 5th year of dividend declaration for Shariah account, while dividend for conventional account has been declared annually since 1952. The dividend for Shariah account in all the years from 2017 to 2021 were lower than the dividend for conventional account of the same year.

The 6.10% dividend for EPF conventional account in 2021 is 17.31% higher than the 5.20%  dividend declared for 2020 (last year).

Calculation: (6.10-5.20)/5.20 = 0.90/5.20 = 17.31%

It is 7.96% higher than the 5.65% Shariah dividend declared for the same year.

Calculation: (6.10-5.65)/5.65 = 0.45/5.65 = 7.96%

In year 2021, there are quite a lot of people has taken out a portion of their EPF savings through i-Sinar, i-Lestari and i-Citra schemes. Hopefully, their money withdrawn from EPF had put in good use. Otherwise, it would be wiser to leave the money with EPF to enjoy the 6.10% dividend.

Sony WH-1000XM4 on-ear wireless headset good for music listening, video watching, phone call handling, online conferencing and gaming

I believe there is no doubt about Sony WH-1000XM4 being the best consumer-grade foldable, stereo on-ear wireless headset with built-in internal echo-cancelling microphones nowadays (during 2021-2022) for music listening with superb active noise-cancelling (ANC) features.

Well, the following criteria are rules of thumb in determining a good wireless headphone/headset:

  • High fidelity of music playback
  • Relatively large driver unit (>=40mm)
  • Wide frequency range at both low end (<=20Hz) and high end (>=20,000Hz)
  • Good noise-cancelling function
  • Long battery life per charge, can last more than 30 hours
  • Support Bluetooth 5 or above. This is crucial for low power consumption as well as low latency between connected devices.
  • Simultaneous wireless connection to 2 or more devices
  • Personalize setting profile with artificial intelligence (A.I.) learning and adapting feature
  • Comfortability for long-hour wearing

There are several brands with top-range consumer-grade headphones that can meet all of the above, including Sony, Bose, Sennheiser, Jabra, Apple, etc.

The Sony WH-1000XM4 is ranked the best among these best with its excellent noise-cancelling function, superb music playback (with the right equalizer setting), advanced A.I. personalization, and nice comfortability in wearing even for the whole day.

However, the Sony WH-1000XM4 is at the same time losing score in its microphone function, bringing doubts of whether it is still good for handling phone calls and/or speaking in online conferencing.

After using it for some time with its latest firmware, I would say its microphone function is still above average, though not among the best. With a simple 3rd party gadget upgrade, it can even instantly be greatly improved to be ranked among the best in handling calls/meetings and also in voice recording for online gaming, podcasting, video narration, etc.

I had been eying for this Sony WH-1000XM4 headset for several months in 2021, but its price tag of around RM1,500 had made me a bit hesitant to buy it, until the last 2021 12.12 online mega sale, when I saw it selling at RM888 promotional price only, I've immediately bought it.

Now I have used this headset for more than 70 hours, most of the time for online conferencing, followed by music listening, and the least usage time is for answering phone calls. I think it's time for me to write my review about this Sony WH-1000XM4 headset based on my past 2 months of 70+ hours usage experience.

Unboxing the Sony WH-1000XM4 headset

This Sony WH-1000XM4 headset comes with a nice carrying pouch, which is a little bit bulky compared with some other headsets, due to its thick ear cups.

also come together with it in its packaging box are:

  • Stereo audio cable for 3.5mm port (without microphone voice out function)
  • Airplane in-flight audio adapter plug
  • Very short USB charging cable (good enough for charging using power bank)
  • Quick reference guide
  • Instruction for online registration of its 15 months warranty
  • Instruction to download the Sony Headphones Connect mobile app for Android and Apple devices
  • A voucher code for 360 Reality Audio 3-months free trial subscription in either one of Deezer 360, Tidal, and Artist Connection.

Adding a table-top tower stand for the headset

I have also bought a 3rd party aluminium headphone tower stand for it, at the price of around RM15 only.

Using the 2 buttons at the left ear cup

The Sony WH-1000XM4 left ear cup has 2 buttons. It is very easy for you to locate the correct button by touching and feeling around them with your thumb, without the need of seeing them. A brilliant UX design!

The upper button is a Customizable button that you can use to control either one of:
  • Ambient sound control
  • Google Assistant
  • Amazon Alexa
I have set this button for Google Assistant, and below is how the button works in this mode:

Continue pressing the button to talk or give command to Google Assistant.

When the headset is actively connected to a computer:
  • Press 1 time to toggle music start/stop
  • Press 2 times also to toggle music start/stop
When the headset is actively connected to your handphone:
  • Press 1 time to tell you the current time. Also to read out your phone's notification (such as SMS) for you, if any.
  • Press 2 times to stop reading the notification
The lower button is the Power button:
  • Press 1 time to tell you the current battery level
  • Long press to turn on/off the headset
By the way, the headset has a proximity sensor in this left ear cup. If it detects that you have removed it from your head, it will automatically pause the music and will resume the music when you wear it on again. It will also automatically turn off itself after you've removed it from your head for several minutes.

Using the touch panel at the right ear cup

For the right ear cup, its external surface is actually a touch panel, with the following functions:
  • Cover it completely with your right hand to enter into quick attention mode to let you listen to your surrounding ambient sound by greatly soften the music and temporarily turn off the ANC. It will go back to normal operation after you uncover the right ear cup.
  • Touch it with 2 fingers to toggle speak-to-chat mode on/off, to let you talk with somebody. In this mode, when there is a human speaking voice around, the music will be paused and the speaker will let you listen to the speech. This speak-to-chat feature can also be set to automatically turn on/off by itself based on A.I. detection of human talking voice, but you might face some minor issues with Microsoft Teams. Therefore, I prefer to manually control it using the 2 fingers method.
  • Tap 2 times (when call is incoming) to answer the phone call
  • Tap 2 times (in a call) end the phone call
  • Tap 2 times (not in a call) start/stop music
  • Long tap (when call is incoming) to reject the phone call
  • Long tap (in a call) toggle the call handling device between the headphone and your handphone
  • Long tap (not in a call) to start voice dial function
  • Swipe up to increase the sound volume
  • Swipe down to decrease the sound volume
  • Swipe forward for next music track
  • Swipe backward for previous music track
  • Swipe forward and hold at the edge to fast forward
  • Swipe backward and hold at the edge to fast reverse

Using the Sony Headphones Connect mobile app

The headset settings can be configured with your handphone using the Sony Headphones Connect mobile app which you can download from Google Play Store or Apple App Store.

The app is able to detect your Sony headset once the headset is paired and connected with your handphone via Bluetooth.

The Sony Headphones Connect app has 3 major pages under the Headphone bottom menu selection, namely: Status, Sound and System.

In the Status page, you can turn off the headphone from there. You can also view the current battery level of the headphone, its connection mode (Bluetooth or wired), the digital audio codec in used, whether DSEE Extreme is turned on, etc.

You can also perform the configuration for Adaptive Sound Control there. This is a very powerful A.I. enabled personalization feature which can adjust the sound output based on your detected action (either staying, walking, running or commuting), or based on your detected location (your home, office, favourite coffee shops, library, or any other places you frequently visit).

For each of the actions and/or recorded locations, you can have different sound settings for volume control, ANC level, speech handling, etc. Your headphone will automatically switch and adapt its sound settings based on its detection.

In this way, it can always optimize your music hearing experience by having adaptive settings that suit for your action or location. For example, you might want to maximize the ANC level at noisy places, but reduce the ANC level in places (such as your workplace) where sometimes you need to speak with people coming to you.

Scrolling down the screen, you can see information about currently connected devices (up to 2), and the current sound output is from which device. The headphone is able to automatically switch between the 2 connected devices based on the voice priority and importance, as determined by its A.I. You can also manually switch the sound output device here, or to select another device to replace one of the currently connected devices.

When you are using Adaptive Sound Control, the sound volume of your headset can be automatically adjusted to a just-nice level, not too loud and not too soft. The A.I. of the headset is able to fine-tune the sound volume for you.

Beside using the app to determine and change the 2 connected devices from the multiple paired devices, you can also perform manual connection directly from the devices itself.

For Android devices such as your handphone, you can perform audio switch from the Switch Audio notification tab.

and for Windows devices such as your laptop or desktop computer, you can do so inside the Bluetooth & Devices setting screen.

The headset is intelligent enough to determine which existing connected device to be replaced. The longer you use your headset, the more accurate its selection will be. 

In case it has disconnected the wrong one, you can always perform manual connection from either the mobile app or the connecting device to get the 2 connected devices as you want.

The last portion of the Status screen shows information of the currently playing music, and the current sound level. The information includes the singer's name, song title, copyright owner, and album name. It supports multilingual display.

Why Sony WH-1000XM4 is excellent for music listening?
  • Sony has the world's leading-edge noise-cancelling technology. The Sony WH-1000XM4 is superb in both passive noise-cancelling and also active noise-cancelling. After you put on this on-ear headset, you can immediately feel ambient noise around you to be much softer, a pretty similar experience with putting on the pilot headset when sitting in the cockpit of helicopter or propeller airplane. With ANC on, you can totally immerse yourself with the music, without disturbance from ambient noise. I have several experience taking a pee and flushing the toilet bowl while wearing the headset. Guess what? I can hardly hear the flushing sound.
  • This headset has a wide frequency range and able to playback the music in high fidelity. You can clearly distinct among the sound from different music instruments, as well as the human singing vocal, and feel their respective distance and position.
  • With its DSEE Extreme technology, this headset is able to improve the music from low bitrate and/or compressed music source.
  • This headset is very comfortable to wear, and you won't feel it "pressing" on your head or on your ears. The length of its band is adjustable, and I don't feel much discomfort even after wearing it for a whole day.
  • Similar to all other on-ear headphones, you can feel some heat around your ear after wearing it for some time. However, unlike most other on-ear headphones, the heat does not continue to build up, and it stays at a still comfortable state, even after wearing it for a whole day.
  • Its fully charged battery can easily last for more than 30 hours, even when you turn on all of its features, even with simultaneous equalizer and DSEE Extreme on.
  • It can work as wireless headphone, as well as wired headphone. It even comes with an airplane in-flight audio adapter plug for you to connect it to the airplane's in-flight entertainment system.
  • Although its 360 Reality Audio feature can only work with several selected online music streaming websites such as Tidal, if you happen to use any one of the supported online music streaming platforms, you will enjoy the great experience of listening to music with 360 degree surround effect.
  • This headset is intelligent enough to automatically pause your music when there is a phone call, or when it detects you take it off from your head. It can automatically resume the music from where it stopped after the phone call, or when it detects you've put it back on your head. It also has feature to soften or pause the music when you speak with somebody around you, without the need of taking it off your head.
  • This headset is highly personalizable. Its equalizer is working pretty well for you to fine-tune your music listening experience.

Why Sony WH-1000XM4 is good for phone call handling?
  • It's Bluetooth connection is pretty stable even though it is quite some distance away from your handphone.
  • It's microphone has excellent noise-cancelling function. Even when you are at a noisy place with lots of people talking, or with TV noise, renovation drilling noise, baby crying, dog barking, motor noise, strong wind blowing noise, etc., those noises will be intelligently filtered out for the other party on your phone. However, if you are in a really noisy environment, your own voice might sound a bit "mechanical" due to the filtering effect.
  • It's right ear cup has touch panel with pretty many features for you to handle your call.
  • Although your voice won't sound as clear and loud as with using headsets with a boom mic, it still can handle satisfactory normally conversation, especially with its latest firmware version. Besides, there is a solution to greatly improve your voice by using 3rd party audio cable with attached boom mic.
  • Other than phone call handling, you can also use this headset to communicate with Google Assistant or Amazon Alexa.

Why Sony WH-1000XM4 is good for online conferencing?

I've used this headset in many video or audio conferencings in the form of Google Meet, Microsoft Teams, Zoom Meeting, Cisco Webex, etc. It can function well in all of them, by setting the conferencing application to use the computer system's audio as input and output.
  • I found that it's Bluetooth works better with computer (PC or laptop) than mobile device (handphone or tablet). Conferencing on computer using this headset has a more stable and better sound than mobile device.
  • Its features such as long battery life, comfortable to wear, does not heat up a lot, etc. makes it suitable for long hour video/audio conferencing.
  • Its excellent noise-cancelling features help you to filter out most of the ambient noise around you, so you can still comfortably have your online conference while you are in a pretty noisy place.
  • Your voice can be greatly improved by using 3rd-party audio cable with attached boom mic. Normally I use this when I am the main speaker/presenter in the online conference. Note that the original audio cable that comes together with this headset only support audio input but not audio output. When getting the 3rd-party audio cable with attached boom mic, you need to make sure the boom mic supports echo cancelling and noise-cancelling.
  • If you are working with multiple computers at the same time, you will find its ability to connect to 2 devices at the same time be very useful.

Why Sony WH-1000XM4 is good for video and gaming?
  • With the correct equalizer setting, this headset is capable to bring you great cinematic sound. It sounds so real to immerse yourself into the video or game.
  • This headset has very low non-noticeable audio latency when connected using Bluetooth, and no latency when connected using audio cable. Your screen's action is in sync with the audio you hear, without any noticeable delay effect.
  • For online gaming that you are going to talk a lot with your partners in the game, your voice will be loud and clear by using a 3rd-party audio cable with attached boom mic.

Some limitation of Sony WH-1000XM4

The Sony WH-1000XM4 will be perfect if the following shortcoming can be resolved, perhaps in the future version of WH-1000XM5.
  • It does not have a mute button. If you want to temporary mute it during a phone call or conference call, you need to do it on your phone dialer software or conference application.
  • Its original audio cable will be perfect if can support audio out, and comes with a good detachable boom mic.
  • It will be nice if its ear cups can be less bulky in design.

All-in-all, if you are looking for a good headset for music listening, video watching, phone call handling, online conferencing and gaming, you won't be wrong getting this Sony WH-1000XM4.
