The sony zx series delivers crisp and clear audio, allowing my kids to enjoy their favorite music, movies, and games without any distortion or interference. Don't think they are poor quality - they are satisfactory.

The sleek black design looks stylish and modern. They are comfortable sitting on my ears and sweating doesn't seem to bother them.

First pair of sony headphones lasted less than two months. Left side of the headphone was broken only 2 months later. It's disappointing that they don't even last two weeks. The earpiece is not 100% comfortable and the head band cuts into the head.

Product is very flaky, and now the metal connector is broken. Cord was mangled and stopped working after 3 months. Contact the customer service for warranty, but physical damage is not covered.
