Pros: Attractive, powerful, fun
This is my fist headphone amp, so I don't have anything to compare it to. I have the Sennheiser HD598 headphones and my first generation Microsoft Zune had a tough time giving them enough power. The CMoyBB makes a huge difference! I can now listen to music as loud, and louder, than I want to. The CMoyBB could easily blow my headphones if I wanted to, that's how powerful it is. There is no background noise, such as hissing or static, from the CMoyBB whatsoever. The bass boost adds the perfect amount of bass, which the HD598 is notorious for not having. JDSLabs customized the CMoyBB specifically to my HD598, however I'm sure the amp can still be used with any other headphones and still sound perfect. Highly recommend this amp!
