These Sony EX Series MDREX110AP/L earbud headphones feature an integrated elecret condenser/omnidirectional microphone and multifunction control button that let you enjoy hands-free calling and regulate music and calls on your compatible cell phone.
I have another pair of Sony Earbuds and wanted them as my second pair. I paid half of what I paid for these for the ones that I previously owned. The quality wasn't as good. I was disappointed. Unfortunately the package was thrown away and I could not return them.
