Summary: It worked fine for a while then the right earpiece started being intermittent. I havent worked out whether its the audio cable where its clamped on, or the red connector that connects it to the earpiece. Either way its not good for a product of this price.
Summary: As a once professional music producer (still signed to a label and making music in my spare time today), sound wise I can't fault these headphones at all - they get 5 stars. After the classic Beyer Dynamic headphones, the HD25 range are perhaps the most famous headphones around - so why only 2 stars? Because of a serious and very obvious design floor that Sennheiser have failed to put right with this products and will end up costing you a fortune.
