Summary: I got these for about £50 ($76) last month and my experience so far has been very good.
The headphones are comfortable and the sound quality is very good for the price. The bass is very punchy, but isn't without detail. The mids and highs are very clear and sharp.
Pros: Very comfortable, detailed bass, clear highs, a durable design and low impedance.
Cons: Not very attractive, ear pads can become irritating after prolonged use.
Excerpt: Sennheiser has sent another of its numerous creations to us, and this time it's a little more high-end than the earlier headphones. It's the HD 465; which I gladly took up for review, though it's not exactly a new piece. Not too many reviews of the device are up, so it deserves mention.
