The black AS210AP Sport In-Ear Headphones with Built-In Microphone from Sony feature adjustable loop hangers for a secure fit while playing sports, a 3.9′ cord for room to move, and 0.5″ drivers that deliver an optimized frequency range. The headphones are splash resistant for all-weather listening and can be used to take calls, issue voice commands, and enjoy your favorite music while you exercise.

They have a frequency response of 17 Hz to 22 kHz and deliver music that sounds clear and detailed. Their open acoustic design helps air flow in, out, and through the back for a more natural sound. These headphones are suitable for smartphones, MP3 players, recorders, tablets, and any other device with a 1/8″ mini-jack connector.
