The headphones are very light and that considering, battery life is surprisingly good - I mean I can use them for about 40 hours with ANC+LDAC, close to 80% volume and heavy bass and still they are at 30%. That aspect is great. Plastic-fantastic all around but sturdy and does not crackle when moved on my head, the earcups are a bit too small for my ears and the lower tips of my ears have to bend to fit inside them - uncomfortable for long listening sessions.
ANC is very good, not at the level of WH-1000XM5/6 but close enough to be satisfied.
By default headphones have very heavy bass, but that can be fun for some situations and there is an equalizer in the control app that works quite well for the others ;) The sound signature is "deep V" but the headphones have the capability to sound quite well with some help from equalizer, thanks to separate high/low speakers - bass does not overshadow mids and highs are clear and crisp without hissing.
I can compare them only with Edifier W860NB and they sound better and definitely have better ANC implementation, less "white noise" when wearing without music playing and there is no "pressure" feeling that I hated with Edifier.
Surprisingly microphones are quite good for phone calls though I did not test them in very windy conditions. I hope there are going to be some easily available replacement earpads because the stock oneas will not live long - they are very delicate.
