What this receiver does

The Ruth's sister C11 is a Bluetooth 5.0 audio receiver with a 3.5 mm jack and a 45 cm retractable cable. It adds wireless streaming to any speaker, car stereo or desktop system that accepts an aux input. The device measures 4.3 cm by 2.1 cm by 1.1 cm and draws power from a 5 V DC source.

Thermals noise and power

The unit runs from a 5 V DC supply and stays cool during typical playback because it has no amplifier stage. Bluetooth 5.0 keeps the link stable up to 10 m with no audible hiss or digital artefacts. The red indicator shows transmitter mode; the blue indicator shows receiver mode.

Build integration

The 3.5 mm plug fits any standard aux port and the retractable cable extends to 1 m when extra reach is needed. No driver installation is required on computers or phones. The compact ABS and metal body sits on a dashboard or desk without blocking adjacent ports. Not for users who need aptX, AAC or memory-card playback.

Questions about this item

How do I connect the 3.5 mm plug and the 45 cm cable to my car aux input?

Insert the 3.5 mm jack fully into the aux port, then plug the USB end into a 5 V port; the retractable cable extends to 1 m if extra reach is needed.

Which part of the receiver will wear out first with daily use?

The retractable cable mechanism and the 3.5 mm connector are the only moving parts; the ABS and metal body has no user-serviceable components.

At what range does the Bluetooth 5.0 link start to drop out during a long drive?

The rated transmission distance is 10 m; obstacles or interference will reduce reliable range before the receiver itself overheats.
