Although I have not bought the headphones at Amazon, but just had time to give my enthusiasm expression. These are the best in-ear headphones I've heard so far. Sometimes when you read that the bass is very lifted for. I can not understand. The Monster has but enhanced bass, where it makes sense (R & B, funk, etc.), in rock and classical music, he seems never overemphasized. The trip is fantastic. No matter what kind of music - treble, mid and bass are always dosed just right. When wearing I feel not the headphones. Processing is also great. Full metal housing, the various earphones can be well on and peel off (is not in every ear, of course)
