I bought these headphones after reading all the positive reviews I read here and I must say that the reviews are pretty accurate - these headphones are great.  For portable headphones they produce bass very well, much better than the ones that came with the Ipod or $30 Sony ear buds.  The mids are clear and the highs are sufficient.  The case is a nice feature and looks cool but its a slight hassle to use.I also have Grado SR-60's which have better sound but aren't portable and not very comfortable for long periods of time.  These Sennheisers are very comfortable and stay on your head snugly which make them great for working out. 

Question: How is the ear?
Answer: these headphones are great
