Ive been using these in my studio and for dj'ing for aslong as i care to remember and there is no other headphone on the market that compares

Im looking for £100 ono

These are an excellent quality make, i bought a set of Senheiser in ear headphones for my iphone 4, expensive for their size but i have yet to hear anything that can beat them for their quality values.
