Summary: These headphones are a terrible investment. I got them for my home recording studio and just playing my acoustic guitar through them just sounds muffled and scratchy. The bass is terrible it sounds like a blown car stereo. I don't recommend these at all.
Summary: Thought this would be a 'good upgrade' from the HD 201. Unfortunately, the head band is much tigher, and the ear cup is a different shape, resulting in it not fitting my ears perfectly like the HD 201 did.
Summary: The sound quality is fantastic but this is the second pair of Sennheiser headphones that have broken within 12 months for me. Both pairs have had the same fault, a lose connection in the cable at the point where the wire enters the earphone.
Summary: Its Very Uncomfortable to wear head start paining after 1 hour use ,Sound Quality is also not that good.Have been using Sennheiser products from past 7-8 years (PX-80,PX-100,PX-100II) all have Great sound and comfortable to use for hours.But with this had worst experience.
