Forget Bose, Buy These!!!


These are the best headphones I have ever had of all time. I have had just about every kind of headphone out there, and there is no way to beat these and spend as much or less.

Immense bass, comfortable fit, long cord, very durable

Absolutely none

Comfortable, Durable, Highly Compatible, Lightweight, Rich Sound

Flimsy Construction

Great bang for the buck!


These replaced the ones that came with my MP3 player. I love how strong the bass is and how good they sound when compared to more expensive headphones. I have some much more expensive regular headphones and these sound comparable, and have better...

Accurate sound reproduction, BASS!!! Fit snugly in my ears and don't pop out

Expensive replacement rubber ear bud covers if you lose them
