So far I have not written a review, neither positive nor negative. After I but the headphones have tried today, I have to share with you my experience of the first day. Previous use: Standard MP3 Player with Sennheiser CX299, CX300, Philips Sports in ear headset and a variety of other tested; Music: Techno and rock Activity: Fitness Center and cross-country skiing in the woods with exercises such as pushups, situps, shadowboxing Now for the headphones: Today came unpacked and started walking Amazingly easy to use, immediately after pressing the Play button I had the bass player of MP3 reduced by 30% (superhot the bums !!!), super grip in the ears without pressure and without pain in the ears reprints the whole 60 minutes ( with all other I had about every minute reprints !!!!) Just buy it !!! Are worth every penny !!!! Even the accompanying bag is great and big enough for the MP3 player. I am annoyed that I've wasted so much money in other (not favorable) headphones.
