When I put the headphones on, with my hearing aid on, ( hearing aid on low setting), I was amazed at the clarity of the sound. The old saying about Bose still holds true today, no highs, no lows, must be Bose. a pesar de esto me gusta mucho como funcionan. These are the closest Ive found to the pro-level in-ears and my 64s are valued at over $800 for the pair. Me costaron 568 pesos. I know part of this is just a brain cramp, but if you guess wrong when assembling - like I did - there just doesnt appear to be a correct way for the pre-drilled holes to line up. I would recommend and reorder. Mic quality is fairly good Id give a solid 6/10, phone call delays voice to headset by approx. it was ok for short time wearing ( max half an hour ) but few days ago we went on a trip and he wear it for more than one hour , his feet on the side were red and so hurtingAnd now i surprised that i can?t return it , i feel sad because honestly this is was his first time with Crocs and seems the last . Theyve continued to come off randomly.
