They are beginning to feel okay after 2 days of a few hours of use per day. Is perfect for travel, easy to sync with your phone and easy to use. Wenn man das Teil zur Hintergrundbeschallung am Arbeitsplatz in "Zimmerlautstärke" nutzt sind nun doch 6-7 Stunden drin. I have never had this issue before with any kind of shoe unless it was far too small. No clarity (sounded like id stuffed my ears with cotton wool before putting the earphones in) and massively compressed dynamic range (the pumping by some kick drum hits was astonishing). My my second grader uses these for his schoolwork during the day ( and I take them right back the minute he is done, lol), and he used to be able to hear me helping his brother with his kindergarten schooling. ***UPDATE*** I was contacted by the company and they apologized and refunded my money. I’ll have to get new ones soon and I won’t be buying this brand again for sure! It is pretty wobbly and unstable however, I dont feel super secure on it. The ear pieces are big, and they can be very loud if youre into that.
