I’ll leave my small review. The headphones are decent, I liked the sound better than the MX4. The sound is clearer, there is no hyper bass that covers everything. Perhaps this is corrected by equalizer, but I listened to them in the stock setting. ANC took some getting used to, probably because these are my first headphones with this technology. My ears sweat a little, although this is more of a design feature, it should be considered when choosing. One important disadvantage - on my head sometimes when wearing for a long time (1-2 hours) begins to hurt the top of the head, apparently because of the thin earcup and have to adjust sometimes. Finding a place where they sit comfortably is problematic, but possible.
