I haven’t found any significant shortcomings yet, I’m just listing the points that, in my opinion, are more successfully implemented in other models:
1. Due to the fact that the model is foldable, the ear cups rotate and fold, there are concerns about the durability of these moving parts. Time will tell.
2. When connected via jack 3.5, the volume buttons on the headphones do not work
3. Noise canceling (ANC) does not want to work without connecting the headphones to anything (via bluetooth or jack). More precisely, it works, but at the same time, for some reason, it actively swears, without ceasing - "Searching for a bluetooth device, the device was not found, connect the device, etc."
4. The microphone is located on the ear, not taken out as a headset. Because of this, either you can hear me worse, or the surrounding sounds are heard too well.
5. The Bose mobile app for some reason hard refuses to work without access to the location, although this is not required for most functions. This, of course, is not a minus of this particular model, but the very policy of such coercion is unpleasant. Dear manufacturers, be more democratic)
