I bought the Solo HD Headphones in Saturn. Unpack and try after me a cracking noise in the right ear immediately noticed. The cracking noise sounded like water in the ear or the like. The problem was even without music. "Claim"! In Saturn the problem was known. The test headphones had the problem and also the next 2 original packaged headphones had a problem. According to the seller, the quality has deteriorated since the headphones are no longer produced in Monster but at HTC (?). The sound should be a bit better, but the process worse. I have now opted for the slightly cheaper SOLO headphones, which are produced directly or by Monster / were. The sound is compared to the HD bit dull (more bass) but I think that even a little better. The HD version has more ups.
If that crackle / crack does not disturb has good headphones. But for the price you should have received a complaint free goods.
