Summary: I purchased these headphones because these things have 50mm magnets and I really like my electronic music with plenty of bass. They do have a decent sound but unfortunately the consequence of the design is that too much heat is generated for comfortable listening.
Summary: I first bought a pair of these 16 months ago and have since got through two pairs. I'd only heard positive things about shure earphones so didn't believe it to be a particularly risky investment.
Summary: These headphones are absolutely gigantic and recommended for indoor use ONLY due to design. I'm pretty familiar with the "Shure" brand as I own another two pairs of their in-ear headphones, however, I wanted more comfort with quality of sound and boy was I disappointed.
