Mediocre active noise reduction: in the subway, it is far from 100% jamming, but there is no pressing vacuum effect, except that the volume is almost not enough for complete happiness. There is a transparent mode, but it's still better to talk, removing at least 1 side from your head.
Below average autonomy: on ldac and max volume lost 15-17 hours, which is worse than all compeors (20 hours are declared), but they can play in pive mode via wire (jack 2.5 by 3.5 mm, non-standard, you need to carry it with you cable) you need to think about charging (((on the marshalls, I forgot about it.
The dimensions of the headphones and the case, the design folds only nominally, the case is the size of a cake, a port for a 2.5 micro jack.
The volume is average, sometimes it’s not enough in the subway even with noise canceling
Indistinct control ons, start / stop with a relief, but for 3 weeks I have not got used to it yet, they are not very informative, sometimes you need to press 2 times + - the volume. The nasty sound of reaching the maximum volume (mutes the music, beeps, turns off only with all notifications, not separately).
Unfinished application on android (no widgets), although the player itself is normal
No tech (nfc, head-off detection, auto-pause when leaning back/removing/voice on air in transparent mode) simple clic old school feel and sound
The microphone is not good, not bad, average, although many scold him
Sound stuttering with interference on ldac is present
Some may seem heavy and bulky, but I followed them)
