For the price, the build quality is outstanding. The sound quality is the same. Bass levels are acceptable for this type of in-ear headphones. The sound clarity is by far the best. When the volume is cranked, these headphones won't break a sweat. Very durable, as well. For this price you can get the Bose in-ear headphones which I previously owned but had very poor audio quality compared to these. Very good for the price!
