Pros: I am not an audio specialist. As a total ignorant in that field I am really satisfied by this product. I use it with a MonoPrix DAC. I am sure this amplifier is not high end quality but the difference with my previous Kingston headset directly plugged to the motherboard sound chip is huge. Sounds are crystal clear, powerful and you can hear small sounds, details in the background. The headset is comfortable and isolates pretty well from external sound, typically cars outside, my computer fans and the fridge not that far from my PC.

Cons: The plastic which makes it feel a little bit cheap
