OQIMAX Bluetooth 5.3 audio adapter — 2‑in‑1 for TV

This compact Bluetooth 5.3 transmitter and receiver converts wired audio jacks into wireless sources or sinks, making it easier to connect TVs, PCs, car stereos, headphones and speakers without changing your existing equipment. It combines two-way functionality with noise reduction and battery operation, helping to add Bluetooth to older systems or to send audio from non-Bluetooth devices to wireless headphones for watching films or listening to music.

Key Points

The unit works as both a transmitter (TX) and a receiver (RX), allowing flexible set-ups for home entertainment or in-car audio. It supports plug-and-play operation and basic call control, so you can answer or end calls and control playback from the device. The integrated noise reduction and CVC features aim to keep voices clearer during calls and reduce background interference when streaming music. 🎧

Battery life varies by mode, with up to 8 hours of operation as a receiver and up to 6 hours as a transmitter according to the manufacturer. Charging takes roughly 2 hours, which makes the adapter suitable for extended listening sessions or for use on the move. Consider that continuous high-volume use may reduce these runtimes.

Signal range is approximately 10 m, which should cover most living rooms and typical car interiors, but walls and other obstacles can affect performance. The unit is small and portable, so it is easy to move between devices or to store when not in use. 🔊

Usage Recommendations

For sending TV audio to wireless headphones, set the adapter to transmitter mode and plug it into the TV headphone output or optical-to-3.5 mm converter where applicable. Pairing is straightforward and usually requires holding the power button until the LED indicates pairing mode. For using with a car or portable speaker that lacks Bluetooth, switch to receiver mode and plug into the AUX input, then connect your phone or tablet for hands-free audio.

Low latency performance is helpful for keeping audio and video in sync during viewing, however, exact latency depends on both the transmitter and the receiving headphones or speakers. If you plan to use the device primarily for gaming or real-time audio, test compatibility with your headphones as some codecs on wireless headsets may introduce delay.
