I paid 15 bucks for these in a sale, regular price is somewhere around 30 - 40 dollars. I needed a simple pair of speakers for a computer, so I had really no expectations. I figured these would outperform s simple 2.0 that was priced the same even worse.
 
Now i seriously underestimated the sound coming out as it turns out this is quite a capable system. Sound is pretty detailed, bass has some punch, given the small size of the sub so there is a lot of value.
 
Design is nothing fancy, but they look much better than those cheap 2.0 systems. 
 
The wired remote is a bit light weight but still a nice feature. Mids and highs are pretty good from the sattelites only the bass starts to suffer when you turn the volume up. So if you are thinking you can host a party with these, forget about it. But if you have a small room, a budget of up to 30 dollars (I would gladly pay 30 for them if I had to buy them again) and want some decent audio - music, movies and games, this is the best choice ... by far.

I bought these headphones for running and sports in general. 
 
Overall I am pretty happy with my purchase, as they do their job well. Sound is nice and clear, adequately detailed for the money, but they lack in bass. They are still ahead of a standard ipod buds. They only do a moderate job in isolation as they are not in-ear, so if your work-our environment is rather noisy, then you should look further. (I personally avoid in-ear buds because although sound is better and they isolate nicely, I think they damage hearing the most out of all headphones)
 
Construction seems adequately solid, and the extension cable is a very nice feature as when i run I have a armband and when I work out i keep my ipod nano in my pocket. Length of the cable is just right for both situations. They fit nicely too, as the clips are easily adjusted. I can confirm that they are resistant to sweat or water. I also like the yellow and black color scheme.
 
Comfort is ok, as long as you don't wear them for long. I have small ears so all ear buds hurt me after a while so I might not be the best example, but they seem pretty large in size.  
 
My only major minus is the unsatisfying bass, which is partly due to this type of headphone usually not having much of and partly due to my small ears so I have a hard time inserting them as they are probably intended. 
 
But for sports or commuting is a good pick. 

I will keep this review short, as I can pretty much confirm what other reviewers have said.
 
They are highly recommended for those seeking a sub 200 $ closed headphone with good isolation (very very little sound leak, and blocks off a lot of ambient noise), good build quality and nice carrying case. I have owned them for over one year and they show no visible sign of wear, every time i put them on it's like I've just bought them.
 
The coiled cable is sometimes not the most practical. 
 
Can work well even without amplification, but they benefit a lot from a good audio source. Purchasers will not be dissappointed.
 
I am curious how they compare to the Audio Technica ATH - M50. (difficult to find a pair in Romania for some reason)
