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, bypassing the eardrums. Because nothing sits in or covers the ears, users can still hear ambient sounds (traffic, horns, sirens, warnings), making them a safer option for outdoor activities such as jogging, cycling, skateboarding, hiking, and skiing. The design is intended to be more comfortable and stable than earbuds for long wear.<br /><br />Key features include a lightweight (45g/1.6 oz) ergonomic wraparound headband that stays secure during activity, a reflective silver safety strip for added visibility, and sweat/water resistance. An in-line microphone enables making and taking phone calls, while a small in-line control box clips to clothing and provides power, volume, music playback (play/pause/skip), and call controls. Connectivity is via a 3.5mm gold-plated connector compatible with most smartphones, iPhones, iPods, iPads, and MP3 players. The cable length is 130 cm (51.2 in).<br /><br />Audio specifications list 100 dB ±3 dB sensitivity and a 20 Hz–20 kHz frequency response; microphone sensitivity is -41 dB ±3 dB. Power comes from a rechargeable lithium battery with up to 12 hours of playback at low volume (higher volume reduces runtime due to the technology’s power requirements). Charging takes about 2 hours via the included micro-USB to USB cable, with an LED indicator for operation, low battery, and charging. The product comes in black with orange transducer pads, includes a deluxe hard storage case, carries a 2-year warranty, and has an MSRP of $79.95.
