Sennheiser HD 457

good sound – Excellent sound but lasted only 2 years :right ear headphone stopped working.Not very comfortable as they press on ears and it hurts.

Excellent – The Sennheiser HD457s are brilliant, giving an amazing depth and quality of sound which far suprpasses anything else that I have tried. They are comfortable to wear and easy to adjust. While this is often overlooked as being insignificant, these have replaceable parts. I have never managed to get a set of headphones to last for, what I would consider to be, their full life. This isn't because of wanton carelessness, but because a single part, usually the wires, stops working and renders it useless.

These are well worth their price and I recommend them to anyone wanting great quality audio entertainment. Amazing sound quality.

Replaceable parts.

Comfort. Nothing that I've found.
