The 35 bucks really lured me for these. As well as how they wrote that because they just took the plastic molds from sennheiser they could spend more money/time on the drivers and iPhone capability functions.
I have a pair of the UB3 headphones. I like them a lot a well. only thing i noticed like Bilal mentioned was they do lean toward the bass side when playing music. don't get me wrong i love bass in rock and hip/hop, rap music but i felt it was a little overpowering to a point where it damped the music. I set my equalizer to rock and now its perfect for my taste. Excellent headphones, especially for $35.
