This review is for the irritatingly named "Monoprice Hi Fi Lightweight Solid Bass Clear and Articulate Acoustic On Ear Headphones with In Line Controls and Built In Microphone", since I can't tell by the product page if ZeeBooth differentiates between reviews of this and the over-ear model. I somehow managed to get them for $18 here, which is only $3 more than what Monoprice charges on their site. Similar to others here, I liked what CNET had to say about them and the price was definitely right. Also my old Klipsch Image S4 earbuds were literally electrocuting my ears any time I moved, so yeah. Those earbuds, side note, are what I had to compare these against, but they were also CNET-recommended years ago for whatever that's worth. First of all, and because people have complained about build quality, they're only $15. At that price point, most people would be okay with (nay, *expect*) a cheaply made product, and would probably enjoy terrible sound quality as well. But these actually sound *good*. So I think we can, at the very least, marginalize that aspect of these headphones. Better construction would mean a higher price, and that would take away the key advantage of these headphones: the value. In terms of sound-reproduction they definitely impressed me. I have a decent HiFi setup at home, the components of which I've also reviewed on ZeeBooth (if anyone's interested); these 'phones obviously weren't able to create as satisfying of a performance as my stereo, but they actually didn't do anything wrong by comparison. Going from top to bottom, the highs are nicely detailed without being harsh or fatiguing. Nothing "crunchy" or brash like most cheap (and even some mid-tier) earbuds have. Mids are decent and don't draw attention to themselves. I would have preferred a little more warmth/richness, but that's technically a coloration and I wouldn't consider its absence an objectively bad thing. Lows are surprisingly well done compared to what I was used to with the Klipsch earbuds. The bass on those was understandably weak, given that they're so small and inexpensive. Which is why the Monoprice headphones pleasantly surprised me by being plenty noticeable and low. It's not sloppy and it's not excessive; it feels well weighted in terms of its place in the sound profile. Overall, the sound quality was satisfying, non-fatiguing, and definitely good for the price. I would give it 5 stars for value any day, and probably 4 for sound quality altogether. The only issue I had was a left-right imbalance where vocals would seem to be centered closer to one ear than the other. Maybe it's because I wear glasses (which also makes listening for more than 30 minutes painful - how do people do it??) or maybe it's the nature of "on-ear" 'phones and the lack of a legitimate seal. Regardless, it was noticeable enough be a little annoying at times. I feel that the discomfort related to my glasses (however irritating) is a personal problem, so it didn't factor into my rating. All things considered, these are an insanely good deal and I would absolutely recommend them to anyone who has reasonable expectations for build quality, a desire for better-than-average sound, and a tight budget.
