Three-in-One Bluetooth Adapter

The Ruth's sister model 0730 is a compact Bluetooth 5.0 audio adapter that works as a receiver, a transmitter and a hands-free microphone. It plugs into any USB port for 5 V power and pairs with phones, headphones or speakers using the M11 device name. A dual 3.5 mm audio cable and an RCA-to-3.5 mm cable are included for wired connections.

Bluetooth 5.0 Range and Codec Limits

Bluetooth 5.0 gives a reliable link up to 10 metres in open space, but walls and interference will reduce that distance. The adapter does not support aptX or AAC, so audio streams over the standard SBC codec only. High-definition audio profiles are not available and there is no Wi-Fi or memory-card functionality.

Desktop and Living-Room Use Cases

The USB-powered design suits desktop PCs, TVs or car kits where a free port is within reach of the 3.5 mm or RCA inputs. It handles stereo music streaming and basic call audio for a single paired device. Multi-room setups, lossless codecs or battery-powered portable use are outside its capabilities.

Questions about this item

Which 0730 version should I choose for a TV with only a 3.5 mm audio output?

The 0730 kit includes a dual 3.5 mm cable and an RCA-to-3.5 mm cable, so it connects directly to a 3.5 mm headphone jack or RCA sockets on the TV.

What does Bluetooth 5.0 actually give me when the 0730 is paired with headphones?

Bluetooth 5.0 provides a stable wireless link up to 10 metres for stereo audio streaming and hands-free calls.

How does the USB interface limit the way I can power the 0730?

The 0730 draws 5 V from any USB port or charger, so it must stay plugged into a USB socket while in use.
