Optical Fiber Bluetooth 5.0 Adapter with TX/RX Switch and Low Latency Audio

This Bluetooth adapter from our range solves a common problem with similar devices: switching between transmit (TX) and receive (RX) modes typically requires powering down and restarting. Our unit lets you flip between TX and RX, and between optical and AUX inputs, using the physical switch and M button while the device remains on. This saves time and avoids the hassle of re-pairing. With two audio interfaces – AUX and optical SPDIF – you get clearer stereo separation compared to single-interface adapters. The adapter is powered by a CSR8675 chipset and Bluetooth 5.0, supporting high-quality codecs including APT-X, APT-X Low Latency, AAC, and SBC. Whether you are upgrading a TV, CD player, or home theatre system, this adapter provides reliable wireless audio streaming with minimal delay.

Features and Construction

The adapter is built around the widely respected CSR8675 Bluetooth chip, offering robust performance and codec support. Its compact form factor houses a 400mAh lithium ion polymer battery for extended use. All connections are straightforward, and the included cables let you set up quickly with most audio equipment.

TX/RX Switching Without Power Down

A standout feature is the ability to switch between transmit and receive modes without turning the adapter off. In TX mode, the adapter sends audio from a TV or CD player to Bluetooth headphones or speakers. In RX mode, it receives audio from a phone or computer to play through a wired speaker system. This instant switching is simpler than competitors that require a full restart.

Dual Audio Interfaces

The adapter provides both a 3.5mm AUX input/output and an optical SPDIF input/output. Using separate interfaces for input and output improves stereo separation compared to single-interface designs. You can choose whichever connection matches your source device for best audio quality.

Codec and Range

Support for APT-X, APT-X Low Latency, AAC, and SBC ensures compatibility with most Bluetooth headphones and speakers. The Bluetooth 5.0 connection offers a range of over 20 metres in open conditions. With a delay of under 40 milliseconds, audio remains synchronised with video, making it suitable for TV and gaming use.

Uses and Placement

This adapter is designed for home audio setups where adding Bluetooth capability is needed. It works well with TVs, CD players, home theatre systems, computers, and mobile phones. The compact size (54 x 54 x 15 mm) and light weight (35g) mean it can sit neatly on a shelf or be tucked behind a media unit.

Home Theatre and TV

Connect the optical output from your TV to the adapter's optical input and pair with Bluetooth headphones for late-night viewing without disturbing others. The low latency ensures dialogue matches lip movements. Alternatively, use the AUX input if your TV lacks optical output.

Music Streaming from Phone

In RX mode, pair your phone to the adapter and connect it via AUX or optical to your stereo system. This lets you stream music wirelessly from your phone to your existing speakers, adding Bluetooth functionality to older equipment without upgrading the entire system.

Multi-Device Connection

The adapter supports a one-to-two function: in TX mode, you can connect two Bluetooth speakers or two Bluetooth headphones simultaneously, both playing the same audio. In RX mode, two phones can be connected, though only the first to play audio will output sound. This is useful for sharing music or audio with a partner.

Benefits and Buying Value

This adapter offers practical advantages over basic Bluetooth receivers. The ability to switch modes while powered on saves time and reduces frustration. The built-in 400mAh battery provides several hours of use, and the rechargeable lithium polymer cell can be topped up easily via micro USB. The included cables mean you have everything needed to start using it immediately.

Rechargeable Battery

The 400mAh lithium ion polymer battery charges via the supplied micro USB cable at 5V DC and 500mA. This gives you portable operation, so the adapter can be moved between rooms or taken on trips. The battery recharges fully in a couple of hours and provides extended listening time.

Included Accessories

In the box you get an optical fibre audio data cable, a 3.5mm AUX-to-AUX cable, a 3.5mm-to-RCA lotus head adapter, and a micro USB charging cable. Chinese and English instruction manuals are also included. This means no extra purchases are needed for standard setups.

Why Choose This Adapter

For anyone looking to add Bluetooth to a TV, stereo, or computer, this adapter provides a simple, feature-rich solution. The CSR8675 chipset, codec support, low latency, and TX/RX switching without power-down set it apart from basic adapters. It is a practical upgrade for existing audio systems, adding wireless convenience without sacrificing audio quality.
