Bidirectional Bluetooth 5.0 Audio Adapter

A precisely sized (59.5 x 22 x 12 mm), lightweight (approx. 25 g) audio adapter crafted from matte-finish ABS plastic for durability and grip. Features identically specified 3.5mm TRS input and output jacks — supporting full bidirectional audio flow without signal degradation. Powered by an internal 140mAh rechargeable lithium battery, offering up to 4 hours of continuous TX or RX operation per charge via USB 5V/0.5A. Bluetooth 5.0 ensures rapid pairing, strong resistance to interference, and stable audio delivery up to 10 meters in open space. Works natively with Android and iOS smartphones and tablets, Bluetooth headphones and speakers, TVs, laptops, gaming consoles, and any audio device with a 3.5mm port — no drivers or firmware updates required. In TX mode: connects to your TV, projector, or desktop audio output to broadcast sound wirelessly to Bluetooth headphones — perfect for shared accommodation or nighttime use. In RX mode: accepts audio from your phone or tablet and feeds it to wired speakers, studio monitors, or car stereos — breathing new life into older or non-smart audio gear. Package includes the adapter, a micro-USB charging cable, and a 3.5mm stereo audio cable — ready for immediate deployment in UK homes, student housing, offices, or rental properties where permanent installation isn’t permitted.
