1 out of 5 eggsPoor Quality

Pros: Pros are the single cord running to it and the adjustable volume.

Cons: Break way too easily. Already had one patron acidently rip the cord from the volume control box. Also had two pairs already start only having sound in the left side of the headset.

Other Thoughts: This is not a good quality headphone for any type of use. I've bought cheap $3.00 ones that lasted longer then these. Don't waste your money.

2 out of 5 eggsCheap but fragile.

Pros: Cheap, comfortable, good sound reproduction.

Cons: I bought 36 of these for my computer lab and within two months two of them have already stopped working. I expect more to fail before the school year is out.

1 out of 5 eggsVery Poor

Pros: * Good length wire
* In line control
* Wire only goes to one side of headphones, helps prevent tangles (see cons)
* Feel decently solid, don't useless fold in half etc.
* Comfy for supra-aural

Cons: * NOT CIRCUM-AURAL, there's no way anyone older than three months has ears that fit inside these cups, they are very much supra-aural, I bought them to be circum-aural as the title says they are, very displeased
* The right speaker (the one the cable doesn't go to) gave out after about a week and a half, I realize that they aren't high quality headphones, but I bought them to replace a 6 year old pair of Koss UR-18's (that were only about $20 6 years ago) which JUST gave out in one ear

Other Thoughts: * At least they were cheap
* I'll be going back to the Koss set for a bit since they both have 1 bad ear, and that pair is much comfier

1 out of 5 eggsBroke After 6 Months

Pros: Good sound quality
Fit very well with little to no discomfort
Good cable length
Nice volume adjustment on cable
Nice looking, don't appear inexpensive

Cons: These things broke after six months. The sound quality suddenly diminished and there was a static-like crunching/clicking noise whenever sound was played. Needless to say, this is a dealbreaker for headphones.

I contacted the company about the matter with no response after nearly two weeks. It's safe to say that I won't be hearing from Coby any time soon.

Other Thoughts: I guess there's a reason there aren't many reviews of these headphones: They're poor quality headphones that only the cheap/foolish end up buying. I've had a lot of experience with different headphones, and I've learned that it's better to buy a good set of headphones than cheap out on a "bargain" pair. If you just invest a little more money in nice headphones that last much longer, than you won't end up buying set after set of cheapies.

I've learned my lesson, so I'm off to get a nice pair from a company that actually responds to its customers when they have a problem with its product.

Verdict: Don't buy these cheap things.
