Pdf Summary

AfterShokz Sportz M2 (Model AS321) are open-ear sport headphones that use patent-pending dual suspension bone conduction technology to transmit stereo sound through the cheekbones to the inner ear, leaving the ears uncovered. This design helps users stay aware of ambient sounds—such as traffic, horns, and emergency vehicles—making them potentially safer for outdoor activities like jogging, biking, skateboarding, hiking, and skiing. The headphones are designed for comfort and stability during extended wear, featuring a lightweight (45g/1.6 oz), ergonomic wraparound headband that stays securely in place.<br /><br />They include an in-line microphone for making and taking phone calls, plus an in-line control box that clips to clothing and provides power, volume adjustment, and music playback controls (play/pause/advance). A reflective silver safety strip on the back of the headband improves visibility. The unit is sweat and water resistant and comes with a deluxe hard storage case.<br /><br />Key specifications include 20Hz–20KHz frequency response, 100±3dB sensitivity, and a microphone rating of -41dB±3dB. It uses a rechargeable lithium battery offering up to 12 hours of playback at low volume (battery life decreases at higher volumes) and charges in about 2 hours via the included micro-USB to USB cable. An LED indicator shows operation, low battery, and charging status. Connectivity is via a 130cm (51.2 in) cable with a 3.5mm gold-plated connector compatible with most smartphones and media players.<br /><br />The Sportz M2 carries a 2-year warranty and an MSRP of $79.95. The UPC is 858510003048.
