SONY WF1000XM4 earbuds, Bluetooth, Bluetooth, in-ear (buds). Active noise cancellation with three modes: OFF; lets outside sound through; completely blocks external sounds. Original foam ear tips. I only used size M myself (very good condition). Original S and L sizes were never used - absolutely new. Touch control, touch management. Control can be customized in the app: you can assign tap functions for each earbud - playback, volume, noise cancellation. Auto-pause when removed from the ear. Equalizer, sound quality can be further adjusted in the app; other additional settings. The case supports wireless charging. I only used it for that. Comes with an original USB Type-C cable, but it is very (!) short - about 10cm, it's just some kind of prank from Sony. Excellent condition! 200 ₾. Happy to hand over personally to you in Digomi or to your courier.
