These are amazing, no complaints from me. I bought them for 12.99 and their worth every penny.
The bass is very good, I'v been using them a few months their still going strong. The material their made from is good, nice build, very comfy to wear, very long cord which is good for indoor use.
They fit my iPod and most other jacks (though I'v only tried a few) I'm sure its fine for most.
