HD-661 Orange : Good monitoring headphones.

First of all, don't expect the same build quality that you might expect from Sennheiser, AKG or Audio Technica, however, the sound quality is exceptional for the cost. It's a fairly neutral, uncoloured sound but with plenty of volume. Comfort levels are good too on account of their light weight, so listening for extended periods of time shouldn't be too fatiguing. Of course the bright orange colour might not be to everyone's liking, but it's unlikely you'll lose them! If you need to kit out a small studio with with inexpensive headphones, these are certainly worthy of consideration. Nice silk bag to keep them safe and clean. Would I replace them? Yes probably. Recommended.
