I bought these headphones about a month and a half ago and I must say that I am impressed with them. I went into various shops and stores to first-hand listen to the quality of the music and test out how my music sounded on the headphones. I bought them from HMV eventually for alot more than the price shown here, but I did wish to try them out in a shop before deciding to buy them without even testing a pair.
After a couple of hours listening to music the headphones start to 'get used to' the type of music you listen to and the quality in the headphones start to increase dramatically. The bass starts getting stronger and each song sounds completely different to the next, in terms of the sounds heard.
In conlcusion, if you have the spare money then buy these headphones! But if you want stronger bass and even louder, intricately developed music I suggest you buy the Studio ones!!!
