Pros: the bass, value, built like a tank, thick and strong cable
Cons: the mids
Its hard to find a headphone that can match this headphones performance at a mere $140. I really can't complain at this price, but if I am to find any fault in it, it is its mids. The mids are not bad by any means but are ever so slightly recessed and sound a bit thin to my ears. Wonderful build quality, you can abuse them, but I dont. Nice long, sturdy, and thick cable. These headphones will clamp very tight when you first get them, but that is very easily fixed. All you have to do is stretch them over a tissue box as you burn them in and viola! Can't beat it for the price. If you want an IEM that is on par with these for about the same price get the Vsonic GR07's, they are like the m50s but with better mids.
