Pdf Summary

The AfterShokz Sportz M2 (Model AS321) are open-ear sport headphones that use patent-pending dual suspension bone conduction technology to transmit stereophonic sound through the cheekbones to the inner ear, bypassing the eardrums. Because nothing goes in or over the ears, users can still hear ambient sounds—such as traffic, horns, and other warning noises—making them a safer option for outdoor activities like jogging, biking, skateboarding, hiking, and skiing. The design is lightweight and ergonomic with a wraparound headband that stays securely in place during most activities, offering improved comfort and stability compared to traditional earbuds, especially for extended wear.<br /><br />The headset includes an in-line microphone for making and taking phone calls, plus a clip-on in-line control box for power, volume, play/pause, track advance, and call handling. It features a reflective silver safety strip on the back of the headband for added visibility and is sweat and water resistant. Connectivity is via a standard 3.5mm gold-plated connector compatible with most smartphones and media players.<br /><br />Key specifications include 100±3 dB sensitivity, 20 Hz–20 kHz frequency response, and a -41±3 dB microphone. It runs on a rechargeable lithium battery with up to 12 hours of playback at low volume (higher volume reduces runtime) and charges in about 2 hours via the included micro-USB cable. The cable length (with in-line controller) is 130 cm, and total weight is 45 g. Color is black with orange transducer pads. It comes with a deluxe hard storage case and a 2-year warranty. MSRP is $79.95.
