The Sony WH-XB900N has a housing made of lightweight plastic material (weighing about 254 grams), which is still sturdy even during intense exercise. The headset has a high degree of flexibility when worn, the joint rotation and movement of the earpads are very comfortable.
The earcups rotate 90 degrees to lie flat and can be folded and placed in a cloth bag or carrying case. When you hold the headset in your hand, you will not realize that you are touching the plastic, but it will have a rough feeling like fabric, the touch control background is also better.
The leather cushion of the WH-XB900N is quite luxurious, and the soft grip is quite pleasant. Full-size ears are very tight and you will have a better listening experience, without much noise.
On the left is the touch control area with a very simple four-way swiping center touch control. In case the battery runs out, you can use the 3.5mm jack and the USB-C port with fast charging.
Sony WH-XB900N not only connects smoothly on all android or ios smartphones. You can choose between NFC or Bluetooth connectivity. Bluetooth still uses standard 4.2 with full codec decoding.
Regarding the Nosie and Ambient noise canceling technology, I feel that it is still not very good, still letting the sound and not isolating the sound like the WH-1000xm3. Still basically used via App Headphones Connect.
The battery life on the Sony WH-XB900 headset is quite buffalo. When using the active noise cancellation function, still up to 30 hours of continuous playback. The headset is charged using the USB-C port, so the charging speed is fast.
