complete junk. DO NOT waste your money on these headphones. the build quality is cheap-feeling even by chi-fi standards, the cable is too short, and the sound is completely off; distorted bass, recessed mids and shrilly treble. there are way better in-ears than this that cost less than 15 dollars. avoid this product unless you like throwing money away
i purchased this item out of curiosity and its relatively low price as I already own other okcsc headphones. The cans have well balanced sound but lacks punch. Bass extends well but limited, midbass is nonexistent, mids are average and higs are very thin. Listening experience is lame. If you want quality and satisfying audio experience, go for this brand XZ1 model, more expensive, though, worth the cost.
