I really like these monitors and have used them extensively! And its true that you will hear things in your mix that you may have never noticed before. I will say that you wont hear lots of low end. Frequency response is 55hz - 20khz. And its a small 5" driver which isn't going to have that low down and dirty club bass. Word? But they are excellent and like they say.. if your mix sound good on these it will sound good anywhere. I really like them! Try them out if you get a chance!
Bought these after replacing my old BX5a's, at the time I was convinced I needed some Yamaha NS10s to accredit myself as a "real" producer, yet ofcourse didnt have the budget.
Ultimately, too much time spent searching on gearslutz.com boards led me to believe these HS50's had a "setting" that mimicked the frequency response of the NS10 (nevermind that they are ported speakers and inherently entirely different). Long story short, through multiple studio moves and being in a smaller home studio, these have continued to be my mains, mainly due being worried about low frequency sound bleed bugging my neighbors.
These speakers are bland for better or worse. I know that I have to scoop some of my high mid before bounce because i have to drive it really hard to feel the same sparkle you would get in headphones.
