Qualcomm Bluetooth 5.2 Audio Adapter

High-end ABS enclosure with patented form factor and internal antenna integration. Core processing powered by Qualcomm Bluetooth 5.2 chip — delivering stronger signal penetration, reduced interference and broader ecosystem compatibility. Functions as both Bluetooth receiver (RX) and transmitter (TX): as RX, streams wireless audio from smartphones or tablets to wired audio systems (speakers, PC soundcards, TVs, car head units) via 3.5mm output; as TX, converts analog audio from legacy devices (desktops, projectors, turntables with preamp) into Bluetooth signals for headphones or portable speakers. RX mode permits simultaneous connection of two mobile devices. Supports full suite of modern audio codecs — SBC, AAC, aptX, aptX-LL, aptX-HD and aptX-AD — ensuring rich, detailed sound reproduction. Integrated microphone enables crisp voice pickup for calls and voice commands. Powered by 3.7V/300mAh rechargeable lithium battery — provides 10–12 hours of usage per charge (in either mode), recharges fully in approximately 1.5 hours using standard Type-C cable, and sustains up to 30 days in standby. Operates in 2.4GHz band (2.402–2.480 GHz), Class II compliant, with -85dBm sensitivity, signal-to-noise ratio ≥90dB and total harmonic distortion ≤0.02%. Verified compatible with Android, iOS, Windows, macOS, active speakers, amplifiers and all A2DP/AVRC-compliant Bluetooth endpoints.
