Yamaha HS 5 MP

Inside a plywood + acoustic foam booth, they sound fairly balanced across the frequency spectre and have more clarity (especially in the mids and highs) than many studio headphones, which is no small feat for speakers. However, you can go slightly 'blind' when mixing when it comes to the low end. It's there, but its representation against the rest of the spectrum can be misleadingly low. If you want a great listening experience with a natural and crystalline frequency response, they're fantastic, but if you want to make sure everyday customer speakers don't get your mid-lows messy, this may not help you. I can imagine the combination of this pair with a subwoofer solves the problem and renders you possibly the best value professional set-up. Final note: they have a quiet hiss, but it may not be in the way unless you're in an incredibly dry and quiet environment.
