2024 Bluetooth 5.4 Transmitter

This 2024 upgraded transmitter adds Bluetooth 5.4 wireless audio to any device with a 3.5 mm jack. It pairs with two headphones or AirPods at once, making it useful for airplane seats, televisions, gym equipment and tablets. A bundled dual 3.5 mm adapter ensures a secure fit on twin-port airline sockets. The Qualcomm chipset handles the wireless link.

Battery Life and Range

A full charge delivers up to 26 hours of continuous playback and the link remains stable beyond ten metres. Recharging via the supplied USB-C cable takes roughly two hours, so the unit can be topped up between flights or workout sessions. The Bluetooth 5.4 connection keeps latency low enough for video sync without audible lag.

Metal Frame and Accessories

The chassis uses a metal frame that resists knocks in a carry-on bag and feels solid in daily use. In the box you receive the transmitter, a Lotus Line cable, the dual 3.5 mm adapter, a USB-C charging cable and a user manual. No additional drivers or software are required — just pair and listen.

Questions about this item

How do I connect the transmitter to the airplane seat and what step is often missed?

Plug the included dual 3.5mm adapter into the seat's two‑pin audio jack, then pair your headphones; the step often missed is holding the transmitter's button long enough to enter pairing mode for each headset.

What upkeep will the transmitter need over time?

Recharge the built‑in battery via the supplied USB‑C cable whenever the 26‑hour runtime runs low; no user‑replaceable parts are involved.

What limit appears first during a long flight?

The battery reaches its 26‑hour maximum playtime before the Bluetooth 5.4 link drops out.
