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 wearer’s cheekbones to the inner ear, bypassing the eardrums. Because nothing sits in or covers the ears, users can still hear ambient sounds such as traffic, horns, and other warning noises—making them safer for outdoor activities like jogging, biking, skateboarding, hiking, and skiing. The design is intended to be more comfortable and stable than earbuds during extended use.<br /><br />Key features include an ergonomic, lightweight wraparound headband that stays securely in place, a smooth matte black exterior with orange transducer pads, and a reflective silver safety strip on the back for added visibility. The headset is sweat and water resistant and includes a deluxe hard storage case. An in-line control box clips to clothing and provides power, volume adjustment, music playback controls (play/pause/advance), and phone call handling via the in-line microphone.<br /><br />Specifications include 20Hz–20KHz frequency response, 100 dB sensitivity (±3 dB), and microphone sensitivity of -41 dB (±3 dB). It uses a rechargeable lithium battery with up to 12 hours of playback at low volume (higher volume reduces battery life) and takes about 2 hours to charge via the included micro-USB to USB cable. It has LED indicators for operation, low battery, and charging. The 130 cm (51.2 in) cable includes the in-line controller, and the 3.5 mm gold-plated connector is compatible with most smartphones and MP3 devices. Weight is 45 g (1.6 oz). The product carries a 2-year warranty and an MSRP of $79.95.
