Pdf Summary

AfterShokz Bluez (Model AS330) are open-ear, bone-conduction Bluetooth headphones designed to deliver stereo sound while keeping the ears unobstructed for better situational awareness. Instead of sending audio through the eardrums like traditional earbuds or headsets, they use patent-pending bone conduction technology to transmit sound through the cheekbones to the inner ears. Transducer pads rest in front of both ears, improving comfort compared with in-ear Bluetooth devices and enabling a stereophonic listening experience.<br /><br />The headphones feature a lightweight (43 g / 1.5 oz), stable, one-piece wraparound headband intended for secure, ergonomic wear over long periods. On-device controls include a make/take call button on the right transducer and pause/advance controls on the left, supporting music, podcasts, and phone calls.<br /><br />Key specifications include a 20 Hz–20 kHz frequency response, 100 dB ±3 dB sensitivity, and a microphone rated at -41 dB ±3 dB. Connectivity uses Bluetooth 2.1 + EDR with A2DP, AVRCP, HSP, and HFP profiles and an advertised wireless range of up to 10 m (33 ft). Power comes from a rechargeable 250 mAh lithium-ion battery, with about 3 hours charging time via the included micro-USB cable and up to 6 hours playback depending on volume (louder playback reduces battery life). LED indicators show operation, low battery, and charging status.<br /><br />The unit comes in black with black transducer pads, includes a deluxe hard storage case, carries a 2-year warranty, and has an MSRP of $119.95.
