If you’re a music lover like me and literally have multiple pairs of headphones from different brands to get you thru the day you know what I mean. I was so excited to finally get these for myself and at first I was having a lil trouble with others hearing me on the phone and now they’re great! I switched the mode from immersion to stereo and found they now last a full work day. I also think I had them on wrong haha but love them and am looking forward to getting my dad a pair for his birthday!
