Bluetooth 5.0 audio adapter

The Ruth's sister adapter adds Bluetooth 5.0 audio streaming to any device with a 3.5 mm auxiliary port. It works as both a transmitter and a receiver so you can send sound from a TV or PC to wireless headphones or pull music from a phone to wired speakers. A 300 mAh battery provides portable use away from a USB power source.

Built for 3.5 mm jack devices only

This unit suits users who want wireless audio on equipment that lacks built-in Bluetooth but offers a standard 3.5 mm jack. It does not help buyers who need digital optical, HDMI or USB audio connections because those interfaces are absent.

10 metre open-space range

Bluetooth 5.0 delivers a 10 metre line-of-sight range at 4 Mbps with -90 dBm sensitivity. Walls or interference will reduce the usable distance so verify the environment before relying on the link.

Questions about this item

Should I choose the transmitter or receiver mode for my setup?

The adapter operates in both modes; use transmitter mode to send audio from a PC or TV to headphones, and receiver mode to stream audio from a phone to speakers via the 3.5mm jack.

What does the 4Mbps transmission rate mean for audio quality?

The 4Mbps rate supports Bluetooth 5.0 + EDR with A2DP for stereo streaming, giving stable playback within the 10m open‑space range.

How does the 3.5mm jack limit what I can connect?

The 3.5mm aux port carries analogue stereo only, so it works with headphones, speakers or car aux inputs but cannot pass digital surround formats.
