The IshGreen AF33 In-Ear Headphones with Clear-Talk Mic from Audiofly are designed for playing back audio and taking calls from your mobile device. The in-line Clear-Talk microphone's answer call button is split from the mic to provide more accurate voice transmission. The headphones themselves feature 9mm neodymium drivers that are housed in an elongated one-piece thermoplastic housing that has a vented design for sound calibration. The right-side in-ear has a Braille marker on its strain relief for quick side identification. 4 pairs of silicone ear tips are included to provide a comfortable fit, while the included microfiber storage pouch allows you to safely store and transport your AF33s.
