Betrusami B101 Pro Bluetooth 5.4 Adapter

The Betrusami B101 Pro is a 2-in-1 Bluetooth 5.4 transmitter and receiver designed for wireless audio streaming. It connects TVs, PCs, airplane entertainment systems, or car stereos to Bluetooth headphones or speakers using a 3.5 mm cable. The device supports dual-link connections for two headphones simultaneously.

Setup checks before ordering

Verify that your source device has a 3.5 mm audio output or RCA ports for the included cables. Ensure your Bluetooth headphones or speakers support pairing mode and the SBC codec, as dual-link mode is limited to SBC only. Note that aptX Low Latency support on your headphones is required to minimise audio delay. The adapter is not recommended for live musical instruments due to latency.

Build quality and daily use

The unit meets FCC, CE, RoHS and BQB certifications for safety and quality standards. A Qualcomm chip provides stable Bluetooth 5.4 connectivity. The package includes a dual 3.5 mm airplane adapter for broad inflight compatibility. Reset is performed by holding the P/R button for eight seconds until all LEDs illuminate. Battery life supports extended listening sessions without frequent recharging.

Questions about this item

What cables and adapters are included with the B101 Pro, and what must I supply myself?

The box contains a 3.5 mm audio cable, an RCA audio cable and a dual 3.5 mm airplane headphone adapter. You only need to provide Bluetooth headphones or speakers to pair with the adapter.

Should I choose the transmitter or receiver mode for my TV and headphones?

Set the switch to TX mode to send audio from the TV to Bluetooth headphones. Use RX mode when you want to stream audio from a phone to a wired speaker or car stereo.

What does Bluetooth 5.4 with a Qualcomm chip mean for latency when I watch a film?

Bluetooth 5.4 and the Qualcomm chip give a stable link, but aptX Low Latency is not supported. With standard SBC headphones you may notice a slight delay, so it is not recommended for live music or instruments.
