Excellent quality headphones, equal to the original set of headphones you receive originally with your phone. Top quality sound. Much better than the OEM version. The sound is crisp & clear, no delays. Good headphones for those people who don't mind the wired variety- excellent back up for wireless headphones incase they run out of power - as these don't require power to work, they run off your phones internal power. Its always handy to have a wired set of headphones as a back up especially when travelling. We love PB Tech & how it has bought quality products to NZ at very fair prices. Thanks PB Tech
