Pdf Summary

AfterShokz Bluez (Model AS330) are open-ear, bone-conduction Bluetooth headphones designed to deliver stereo sound while keeping the ears unblocked 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. This makes them suitable for users who want to stay aware of surrounding sounds—such as traffic warnings outdoors or conversations in an office—while listening to music, podcasts, or taking calls.<br /><br />The headset features a lightweight (43 g / 1.5 oz), ergonomically designed, stable one-piece wraparound headband with transducer pads that rest on the cheekbones in front of the ears for improved comfort during long wear. On-device controls include a make/take call button on the right transducer and pause/advance controls on the left.<br /><br />Key specs include 20 Hz–20 kHz frequency response, 100 ±3 dB sensitivity, and a microphone rated at -41 ±3 dB. Connectivity is Bluetooth 2.1 + EDR with A2DP, AVRCP, HSP, and HFP profiles and an estimated wireless range of 10 m (33 ft). Power comes from a rechargeable 250 mAh lithium-ion battery, charging in about 3 hours via the included micro-USB cable and offering up to 6 hours of playback (dependent on volume). LED indicators show operation, charging, and low-battery status. The product 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. UPC: 858510003055.
