Yamaha HS 5 MP

I use these for quick and easy audio playback next to my PC monitor, from the Focusrite 2i2 into a small mixer and split out to these and my Adam T8Vs.
Pros - really nice top end, great clarity, and a better soundstage than I was expecting from how they sit in the environment (quite close to back wall). Excellent build quality and enough adjustability with bass and treble switches for room control. Looks are also a plus point.
Cons - not really a big negative as it's built into their design, but the 5" driver low end does ramp off quite quickly - so for bass I'm checking the Adams and my headphones. But that is not a fault or flaw of the Yamahas, as they do their job exactly as intended.
Would recommend.

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.
