Prior to purchasing these headphones, i had always tried to steer clear of 'in ear' headphones, opting to have the traditional ear bud that sat on the outside of your ear. A lot of my friends have products from Bose, Klipsh and even Dr Dre that were all in-ear buds, and after them constantly telling me that i "didn't know what i was missing" i decided to get myself a pair, after researching a lot on the Sennheiser website (must declare i have a bias for Sennheiser products), these looked like the real deal.
I wanted an ear phone that was going to give me a balanced sound, i didnt want it too heavy on the bass, but at the same time i didnt want it to be treble heavy with no real warmth of power to the music, and these phones deliver just that. Upon first opening the box, you get a great variety of different ear pieces you can fit onto the ear bud, and once you find the right one (when i say right i mean most comfortable) you put them in your ears and a lot of sound is blocked out straight away, allowing you to hear pure music. These ear buds sound great, a real sense of clarity is heard (although not at first, but once they've burned in a few hours) throughout all genres of music, but there is also a serious level of bass presence too, with even demanding frequency bass found in R&B/Hip Hop songs sounding superb and full of richness.
If you are looking for an headphone that is non-intrusive, great in sound and build quality and simply looks neat in appearance then look no further, the integrated sound control is a great extra too!
