Suuuuperb battery backup & audio quality
Battery backup is as advertised, delivered on 3rd Jan 2022 and still holding at 50% battery on Jan 13 with an average use of 8 hrs a day.
Connectivity is not stable, particularly during calls audio crackling often.
Comfortable on the ear, but the battery unit being quite thick is good when upright, lying down makes is move around your neck depending on your position. I usually watch TV lying down with the device.
Sound quality is reasonable for the price, mids are ok, bass on the lower side, treble non existent. But all in all passable sound quality, nothing great and nothing to particularly complain about.
Delivery took more than a week, not sure of replacement or repairs, I guess if you get a defective unit you may end up waiting for long to get replacement and service centers are limited, at least there isn't one in Bangalore.
