Pros: Cost effective
Cons: Sound quality, poor bass, uncomfortable, no seal/poor fit
The main issue I really have with these headphones is the way that they fit. I struggle to find a way to wear them comfortably or get any sort of a seal.
Sound quality is sub-par, even for the value. I haven't had many over the ear headsets that I prefer these over for music, including mic/gaming headsets that aren't made for it. They do sound much better with an amplifier, but at the point of buying $20 headphones and a $50+ amp, you're better off dumping the extra money into better headphones.
