These are considered entry level IEM's. So I had them for over a month now to let their sound signature burn in. From what I've noticed, these IEM's are geared more towards the high's. The bass is lacking and often times drowned out by the excess high's.

The biggest concern (is also the selling point) is the flat tangle-free cable. My biggest concern with them is the noise it generates. The surface area really has a toll on the amount of noise. Also when shuffling around, a simple contact with the cable will generate noise. It is extremely annoying (at least for me) to wear outside while walking.

I would not recommend these headphones as there are plenty of competitors that simply do much better.

I purchased these headphones way back when they were still expensive. It was my first pair of IEM's and I was quite happy with them.

After using them for a few years, the actual headphone jack connector came loose from the casing that holds it. So right now it is just dangling around. I have not done anything to harm them, they have just become loose from many tugs and pulls. The design of the straight headphone jack is just not as strong as the angled ones.

Also, the cable showed rips along the seams of the cable. I temporarily fixed it with a black rubber solvent.

Other than those flaws, the sound is pretty decent, with it focusing more on the low end. I listen to only rock and ideally it would be great for Hip-hop, dance and music more bass centered.
