Pros: These are really good compared to what my laptop has built in. The sound is much clearer, more detailed. More comfortable than my old ear buds. I'm a fan! They sound much louder than when using the built in pc speakers so I suggest lowering the volume before insertion.
Cons: Wish they had a built in mic and volume controls.
Summary: Not the worst headphones I have ever owned either and, to be honest, considering they retail for less than $30 and I got them for less than some I have seen next to gum in a checkout line I think they are a fairly good bargain.
Pros: Inexpensive, durable and comes with 3 sizes of earpads so you get a better than average chance of having them fit well. I purchased these as a low cost headphone to use at the gym because I keep tearing up every set I take there and figured I better just get something inexpensive yet acceptable. They were that and so I consider these a success, but if you are looking for high fidelity sound to enjoy in a non-gym setting then you may want to get something better.
Cons: Must be in your ear "just perfect" to get the optimal sound. If they are in too far, not far enough or they are loose and shake into a non-optimal position the sound degrades from above average to poor. That's all more of a factor of the type of headphone it is though as opposed to a quality issue with the hardware itself though so consider that before buying.
Summary: Since I live upstairs and the walls floors are thin, by using these plugs, I dont bother the people below, AND I hear the shows in my sleep, and i have wonderful dreams as a result. Cords are very strong and will hold up well.
Pros: I use this to extend to my bed room 26 inch hdtv to watch netflix. sound great and I have no trouble wearing these in my ears after I fall asleep, they actually help block out side noises getting into my room, and I sleep much better.
