I purchased the Turbines on friday (from FS), and they've been burning in for about 30hrs now and i just wanna share my comparisons with these phones to my current everyday phone the Atrio m5 v2.
When i first unboxed the Turbines (great packaging) and plugged them in, i was surprised as to how clear they sounded but the bass was pretty booming. Having purchased the Atrio for the reason of having great bass in an IEM, i enjoy a good amount of bass in my music and rarely do i find a headphone to have too much bass....well at first i thought the Turbines had TOO much bass. I remember reading that the bass cools down after some burn-in and was happy to find out that it did maybe after 6-10hrs.
I find that achieving the proper seal is a bit tricky because i have to really shove these into my ear canals, as opposed to the m5 where they seem to sit more lateral to my ear canal. Trick is to keep pushing them in, until the bass is crazy...because the bass IS crazy. I think i might enjoy deeper bass with the Turbines than with the Atrio m5. With music like rap, or electronica, i find that the turbines go really really low, but when it comes to more "natural" bass (drums, guitars, etc...) the Atrio are more refined.
On the other end, i think the Atrio has better soundstage, instrument separation, and an overall smoother sound. They just sound clearer to me, voices are better rendered, and i feel more surrounded by the music. Everything is still nice with the Turbines but the music is much closer to my ears and less "around me".
As far as the cables go, eeeeech, i think my Turbines aren't gonna last very long. The buds are quite heavy and the cord is so thin and i dunno they just seem like they're gonna come apart at any moment. We'll see time will tell, especially since these are my gym pair now.
Final verdict. At 100USD, these are a steal, i dont think that bang for your buck that there is a better headphone out there, especially if you wanna feel the bass in your music, but at the usual price that's normally 180$ CAD here at least, i would spend the extra 50$ and get a pair of Atrio m5, because sound quality is comparable and just slightly better than Turbine (IMO), but the build quality of the cable is really really nice...i'm not the type to baby my earphones and my atrio still look brand spanking new. Just my 2cents
