I had a set a while back, talking original chunky ipod days so more than 7 years ago, they used the be 'the' headphones to have but there wasn't much high end competition back then like there is today..
Anyhow they were good, but did protude the ears quite a bit, though Im sure they are much sleeker nowadays. Another thing I remember was the ear buds hurting my ears if wearing for prolonged periods, they do however do custom ear buds if your willing to pay extra. So worth trying a set on first.
I just wear some cheapy ones myself now though, after losing or stepping on the expenisve ones and spending far too many nights in techno/house clubs during my yoof to notice the difference anymore..
Decent brand though with alot more crudentials than the likes of Beats etc
