Nedis BTTR050BK is a compact wireless audio transmitter that sends stereo sound from a non‑Bluetooth source to Bluetooth® speakers or headphones. The transmitter supports the A2DP profile and the SBC codec for standard stereo streaming. It connects to source devices using the supplied 3.5 mm audio cable (AUX) or via USB power and features an internal 500 mAh battery for portable operation. The small black enclosure (30 × 59.2 × 13.5 mm) and simple LED indicator make the unit easy to place and monitor during use.

Advantages

Compact size and included 3.5 mm cable reduce installation complexity and enable discreet placement near the audio source.

How to use

Connect the supplied 3.5 mm cable between the Nedis BTTR050BK and the audio output of your TV, media player or other source. Power the transmitter from a USB port or USB power adapter; the internal battery will allow temporary operation if USB power is not continuously available. Put the transmitter into pairing mode following the indicator LED instructions, then pair it with your Bluetooth headphones or speaker using standard Bluetooth pairing on the receiving device. After pairing, play audio from the source device; the transmitter will forward the stereo signal over Bluetooth using A2DP/SBC.

Usage recommendations

For best performance, keep the transmitter within approximately 10 m of the paired Bluetooth receiver and avoid obstacles or interference sources such as large metal objects or crowded Wi‑Fi environments. Use a stable USB power source for extended sessions to prevent battery depletion. Ensure the source device output level is set to a moderate level to avoid distortion and verify the receiving device supports A2DP for stereo playback.
