I love flying, but I really hate airline headphones: the sound is usually awful, they’re uncomfortable, you never know how clean they are, and the cables feel like a bad joke in 2026. In this video I unbox and test the Syntech Bluetooth Transmitter, a tiny gadget that lets me use my own Bluetooth headphones with any in-flight entertainment system (or any device with a 3.5mm jack). I show what’s in the box (including the airline adapter and travel pouch), explain RX vs TX mode, and why the included two‑prong adapter matters on planes so you don’t end up with audio in only one ear. Then I walk through pairing step-by-step with different headphones (Sony Hear On 3, AirPods Pro 2, AirPods Max, and even AirPods 4-style pairing). My biggest practical tip: if you’re pairing AirPods, turn off Bluetooth on nearby Apple devices first—Apple’s ecosystem loves stealing the connection. Finally, I test it on an Emirates Business Class flight and it worked perfectly, which is exactly why I prefer a transmitter over “built-in IFE Bluetooth” that often forces you to pair from scratch and isn’t reliable. I also compare it to my AirFly Pro: the Syntech wins for me thanks to the screen, volume knob, and multi-device memory—at about half the price, even if latency is slightly higher.
