It work well as handsfree for my lumia, my razr and my wife's iphone. But the controls only work fully on lumia, on iphone only action middle button work while on razr any button i pressed brinv me to voicecommannd, LoL. Yet it is clearly written on the box, so you got what you expect ;)
SQ wise, i always thought monster's ranges from the turbine, dre,etc as overpriced boombox. Surprisingly, this one is entirely different animal. Yes the bass are more pronounced but it's nicely controlled and accurate without exaggeration. The mids are nice, the highs bit rolled off but still there. Overall, the most balanced and neutral amongst monster creations.
It also sounds great out of the box, quite rare since usually headphones/speakers need burn-in time forthe sound signature to settle. I dontknow how it will sound after used several hours but i'm on my second day now and it grow on me. I like it more now than my UE Superfi i've been using for 2 years.
Recommended to try!
