I've owned these for approximately 2 years. I've ran the gamut.

1. The first problem you'll notice is there is NO power switch. These are on all the time, sucking your power and have a bright green LED that will never go off now, unless you plug it in and out each and every single time [on a surge strip buried under my desk? No thank you.]

2. Around ~8 months into use, a VERY annoying high pitched low screeching sound was heard, constantly, during playback and even if I unplugged the minijack cable. The only solution was to BANG it, and then it would stop. Or unplug it altogether. Overall, it happens sometimes, waking me up in the middle of the night.

3. The sound is muddy, and dark. I was basically like a boiling frog. I had no idea how bad the sound quality on these was, until I put them side by side my brand new Logitech Z623's. Those BLOW THESE OUT OF THE WATER! I COULD NOT believe the crystal clarity of the Z623's, I was hearing sounds I've never even heard before in my music come forth from these beasts. The bass was punchier, the highs cleaner, I actually felt like the symbal was being crashed right next to me, the snare sizzled.

I plugged the audio jack back into the Klipsch's, and it felt like day and night. Everything just sounds hollowed out, and muddier. Like I was suddenly slightly deaf.

Do yourself a favor: Get the Z623's.

You won't be sorry.

Music I listen to: Heavy rock, metal, electronica, trance. But anything sounds great on the Logitechs. I mean anything.
