Travel-ready audio adapter

The LAICOMEIN B110 is a compact Bluetooth 5.4 transmitter and receiver designed for travellers who want wireless headphones on aircraft seat-back screens, hotel televisions or gym equipment. It includes a dual-prong airline adapter so it fits both modern 3.5 mm jacks and older twin-port armrest sockets. The pocket-sized unit weighs only 0.09 kg and operates on an internal battery.

Thermals noise and power draw

Because the device has no active cooling, it runs silently and generates no noticeable heat during typical use. Power consumption is limited to the Bluetooth 5.4 radio and the aptX Low Latency codec, drawing only the energy needed to maintain a stable link up to 33 feet. A full USB-C charge reaches 100 percent in 2 hours and delivers up to 20 hours of playback.

Sustained-load behaviour

On long-haul flights or extended TV sessions the battery supports the full 20-hour rating without performance drop-off. Bluetooth 5.4 improves connection stability by 72 percent and cuts latency by 66 percent compared with earlier versions, keeping aptX Low Latency under 40 ms throughout the session. The adapter is not suitable for live instruments, karaoke or Bluetooth hearing aids.

Questions about this item

How do I connect the B110 to an older airplane seat with a dual-prong jack?

Plug the included dual-prong adapter into the armrest ports, then insert the B110's 3.5 mm plug into the adapter; set the switch to TX mode and pair your headphones — the first pair connects, then the second pairs automatically after the first is linked.

What charging routine does the B110 need to keep the battery healthy on long trips?

Charge fully via USB-C for 2 hours before each flight; the 100 % charge delivers up to 20 hours of playback, and regular full cycles maintain capacity better than frequent partial top-ups.

At what latency does aptX Low Latency become noticeable during extended TV or gaming sessions?

aptX LL stays under 40 ms; beyond that threshold lip-sync drift becomes audible, so keep the B110 within 33 feet line-of-sight to maintain the low-latency link.
