Here's a headphone I got from Musical Fidelity direct. It's quite close to neutral, with a very slight mid-bass bump, color-free midrange, and smooth treble. It is on-ear however, it has low isolation, and a fairly strong headband clamp. If you're looking for really good sound in this price tier and are OK with these features, then I'd say highly recommended. As an aside, I've been told by a couple of users that some companies who are well-regarded for speakers and other components, who make headphones for the first time, often don't get involved in the design and end up putting their brand name on an inferior headphone. Not this time.
