Guys, this is fantastic) It turns out that we don’t hear so many sounds in ordinary headphones. If you want to buy a really cool gift for yourself / a loved one - take the XM4, this is the entrance to a new world of music enjoyment. With its pros. Materials, assembly, setup, case, sound, control - it's all at the highest level. In terms of wearing comfort, I’ll say that when you put it on, it’s very comfortable, it doesn’t press anything, but after a few hours you still feel the headband. Separately, I would like to highlight noise reduction - it turns out that we live in such constant noise and do not know what silence is. I'm looking forward to my first flight on an airplane. And of course, like a cherry on top, support for connecting to two devices is now just a must have. Got cons: - It's a pity that Sony cut out support for aptX (there is in XM3), so I recommend to study the issue of codecs and understand what you will use with (maybe it's better to buy XM3 for your specific case). Spoiler: for Apple gadgets, take the XM4. - I would like to still have more battery life, but this is not critical (for a day there is enough very active use). - Well, the voice through the microphone is somehow not to say that the interlocutors can really hear well. For recording podcasts - definitely not)
