Summary: I use these speakers at work, day in and day out. Using the supplied cables straight out of an iMac, they sound awful. Instead, I'm using a iBasso D7 and a Belkin PureAV cable and it really cleans up the sound a lot.
They are relatively well balanced speakers. A bit muddy prior to burn-in, but they're much better now. The bass is certainly lacking, but that's to be expected with such a small cabinet.
Pros: Decent Balance, Clear sound, Better than most "computer speakers"
Cons: Lacking bass (to be expected), questionable workmanship, horrible customer support
Summary: I bought these looking for high quality sound for music from my PC. In hindsight I should have bought a some bookshelf speakers and a small amp. It's not that this product sounds bad, it sounds reasonable for the price. And the integrated amplifier is convenient and a space saver. The speakers need to be placed very carefully in order to hear their full potential.
Pros: Mostly good sound. Aux in. Can go very loud.
Cons: Fiddly set up. Boomy middy-bass, low quality headphone circuit.
