SONY WF-1000XM4 Put to the test



Pairing up with device via bluetooth

Remove both units of the headset from the charging case. The earpiece enters pairing mode automatically if it hasn’t been paired before. When you pair a second or subsequent device (if the headset has pairing information for other devices), put the headset units into both ears, then hold your fingers to the touch sensors on both the left and right units for about 5 seconds. When the touch sensors have been operated correctly, a beep will sound.

Turn on the device, smartphone in this case and pair it as a bluetooth device.

Once that is done you can start streaming your audio from your smartphone to the earphone. 

You can also pair it up with a PC, click the link for the instructions.

In our test, the WF-1000XM4 is able to basically filter off most of the noise when the volume level is set at around 60% we are travelling on the MRT. The Transport  filtering is probably too aggressive as it also filters off the announcements. So, do take note and don’t alight at the wrong station.

If you want to be able to modify the default settings, you can do that within the app. You can adjust the levels of ambient sound 1 to 20 (background noise). You can also turn on Focus on Voice detection to amplify the voice levels when speaking to friends without removing the earphone for 4 different environments – Staying, Walking, Running and Transport 


Sound quality is excellent and the bass is excellent. 

Battery life is very good. So far, I only charge it once after days of use. You can also use wireless charging to charge it up.


An excellent bluetooth earpiece that effectively cancel all the noise around you be it your neighbor’s barking dogs or reduce the noise from construction work nearby.
Enjoy your favorite artiste singing in a new dimension never heard before with that clarity and bass level. Pair it up with your TV bluetooth and enjoy the superb bass in action pack movies.
As for voice conversations over the earpiece, voice clarity is there and I didn’t experience drop packets.
The probable only complain about it would be the pricing. Priced in the range of SGD 299 ~ SGD 349, it is quite an expensive ear piece that deserves such a high price tag.
It really helps to increase my productivity as it greatly reduces all the background noise in my surrounding. Thanks for such a great product.
It is also available on Amazon at USD 278
