These Sony MDRXB450AP/B headband headphones feature an in-line microphone for hands-free phone calls. Coupled with neodymium magnets and 30mm drivers, the Acoustic Bass Booster technology generates enhanced bass response.
My daughter wanted something to replace her ear buds, but was on a limited budget. She did the research on these headphones and has been totally happy with the purchase. Great sound quality and good value.
