Conclusion: Overall, these headphones have been outstanding and I am very happy with them. They have gotten many hours of use over the last 2 years, and they have been completely reliable with no degradation in sound quality or comfort. They are a bit pricier than other headphones, but are worth the investment if you plan to do a lot of listening at home and enjoy the higher level of sound quality that a good pair of headphones can provide.
Excerpt: Sennheiser knows how to make great products and these are the best around for their class and price point. They are very comfortable to wear and have great sound. Also, they fold up nicely to tuck away in a bag or case. Excellent for home studio use, AV production, or listening to your favorite music on your home stereo system. Also very handy and recommended to have a few for your pro studio. Sennheiser also has user replaceable spare parts available.
