Great value for the money
For the price I don't think there is much out there that can beat these. I used them for silent practice on guitar and they work great. The have a surprisingly good bass response.
One downside is that they feel a bit "cheap". The weakest point is the cord. I've had several of these and they never last more than a year before the cord breaks internally.
These have a great price/sound ratio and I would definitely recommend these but be aware of the poor quality of the cord.
