So, first off, I saw these on sale in Target for around $40 so they were an impulse buy. I think they originally retailed for a lot more, but I'm guessing you can get as good (if not better) quality on-ear headphones for the $150 asking price. But, heck, for $40 they were worth a shot.
Now, the sound quality of these is pretty good. They seem quite bass-heavy like Beats, but definitely not as bad or overpowering as those. They're actually quite balanced and after a bit of burn-in they've improved, but I'd still prefer a bit more sparkle at the top end (sorry - I'm not audiophile/expert so forgive my terminology). I've used Sennheiser headphones before which offer a more balanced sound, but without the thudding bass. The Monster NTune are also very comfortable with a memory foam headband and they don't pinch, resting nicely on the ears with no pain. They have an in-line mic for mobile use (it's just a single button affair) and the cord is thick and rubbery and can be detached. It only attaches to one side, so that's convenient.
But here's the thing: they're just not that pretty. The shiny, blingy "spinny rim" look made me feel very self-conscious when walking the streets and they also stick out a long, long way, so I resembled the Katamari guy in that old video game. I really wish they were a little more subtle, because for mobile use these are comfortable and sound good. As vain/stupid as it sounds, I just can't deal with the shiny plastic and red/silver accents, which is a shame. They're clearly youth-oriented, and that's cool, but just beware of that if you buy 'em.
So, instead, they've become my at-work headphones and the convenient mic means I can use them for Skyping. They work well for just general music use listening to tunes off my Mac and are comfortable to wear for long periods.
