Bluetooth music receiver Nedis BTTC2500BK — 3.5mm + USB interface, 8 m range, Li‑Ion 150 mAh battery

Nedis BTTC2500BK is a compact Bluetooth music receiver designed to add wireless audio streaming to wired speakers, car stereos or headphones. It supports Bluetooth 5.4 and common audio profiles including SBC, A2DP, AVRCP and HFP. The receiver offers two connection options — a 3.5 mm analogue output and a USB host interface — and can operate wirelessly up to approximately 8 m. Power is supplied by a built-in 150 mAh Li‑Ion battery providing around 8.5 hours of playtime or continuously via USB power. The unit measures 28×61×14 mm and ships with USB‑C and 3.5 mm audio cables for immediate setup.

Advantages

The device combines a small form factor with Bluetooth 5.4 for stable connections and low latency in typical listening scenarios. Dual interfaces (3.5 mm and USB) give flexible compatibility with many audio systems without requiring additional adapters. A rechargeable Li‑Ion battery enables portable use when USB power is not available, and the included cables simplify installation. Support for A2DP and AVRCP allows wireless music control, while HFP adds hands‑free call handling when connected to a phone.
