Summary: To be perfectly honest, when I first heard of the Turbines, I thought that they were just another Monster consumer product like Beats. That is, heavy, muddy, bloated bass, recessed mids and highs. When I first heard them, I was pleasantly surprised and I don't own these.
Pros: Strikes a good balance between neutral and fun, Build quality seems pretty good, L and R markings
Cons: Very hard to find correct insertion depth, Lacks detail, "Monster" branded
Summary: The Monster Turbine in-ear headphones are very good bang-for-your-buck IEMs. The bass seems slightly more powerful than other aspects of the sound signature to me, but some people like this type of sound and to be fair the bass is not bad.
Pros: Good sound, relatively precise. Awesomely decent.
Summary: These are some great earphones! The bass and sound quality is great, and they are very durable, though the mids are very recessed and muffled. They stay in my ears very well, and are pretty comfortable and do not hurt my ears at all.
Pros: Amazing Bass, Great Highs, Do Not Fall Out Of My Ear, Very Durable
Summary: This is my first time using a pair of decent IEMs, I have to say, I am not disappointed.
Fit : This is the turbine's worst aspect. I have rather small ear canals and used the smallest round tips it came with, it was perfectly fine, but the smallest tri-flange tip refused to go inside my ear canal...
Pros: LOTS of accessories, metal housing, Monster Cable brand name.
Cons: Very hard to find the perfect fit, microphonic cable
Summary: I'll say right off the bat that this is my first pair of remotely high-end headphones, and one of my first major reviews. So try to forgive incorrect terminology or generally novice-sounding terms.
Pros: Decent isolation, powerful bass and low end, overall good sound quality (with right fit)
Cons: Just don't work in my ears, occasionally muffled mids and vocals
