I found the Sony WH-CH720N headphones to be comfortable and the battery to be durable, despite medium to high usage. The power button is distinct from the others, as well as providing the current charge (with a click).

Sound insulation is satisfactory, as it allows for a quieter room than usual with the door closed. Sounds or discussions at a low to medium degree are muffled well and almost well when medium or a bit more.

Charging takes a while, even with a 2-amp charger, about 3 hours (if charging when the battery is around 30%).

Comfort-although subjective and also due to how careful one is with it-is quite good.

If you wear prescription glasses you might notice, like almost if not all headphones of this type, more pressure.

However, even the pressure in the ears is not so great. But after 30 minutes or more in any case you might feel it, as well as sweating, particularly in humid and hot weather.

The volume can be adjusted both from the buttons on the bottom right, and of course from the computer (where the remaining charge also appears).

And the sound isolation button is also located in that area of the headset.

While on the left we find the power on/off button (held down for about 3 seconds), as well as the jack for connecting headphones, and the c-type slot.

In addition, the headphones are also equipped with a microphone, with a similar output to smartphones (perceived quality is about 128 kbps or 44 kHz).
