Dual-Ear AI Translator Bluetooth 5.4

A pair of intelligent earbuds engineered for accurate, responsive language translation in real time. Built on Bluetooth 5.4 architecture for rapid device discovery and robust signal retention within 10 metres. Carrier frequency conforms to standard 2.402–2.480 GHz. Audio fidelity covers full human hearing range (20 Hz–20 kHz) with 3 mW driver output. Individual earbud battery: 3.7 V / 50 mAh; charging case: 3.7 V / 400 mAh. Runtime: 6 hours per charge; recharge time: 1.5 hours via Type-C port. Physical dimensions: 13.8 × 5.5 × 1.4 cm (unit), 13.3 × 8.2 × 3.3 cm (box). Unit weight: 80 g; boxed weight: 145 g. Accessories include earbuds, Type-C cable, printed manual, and branded retail packaging. Core functionality centres on cloud-connected AI translation supporting 138 languages. Speech is converted to target-language audio and on-screen text simultaneously. Translation engine leverages multi-domain vocabulary databases and dynamically selects the lowest-latency server node based on geographic proximity — achieving ≤0.5 second response times and up to 98% accuracy. Interaction methods include direct earbud touch (for immediate speaker activation), smartphone screen taps (top/bottom half for speaker/listener roles), and mutual headset pairing for spontaneous bilingual exchange. Ergonomics prioritise secure fit and minimal pressure: the hanging-ear profile rests comfortably behind the earlobe. HD noise reduction improves speech capture in wind, traffic, or crowd noise while preserving vocal nuance. Sound quality benefits from 16 mm dynamic drivers tuned for vocal clarity and spatial presence. The companion app enables supplementary functions — voice logging, transcript export, AI chat, and visual prompt tools — all integrated natively without third-party dependencies.
