Implementing Bluetooth 5.0 which is backward-compatible with Bluetooth 4.0, 4.1, and 4.2, the company ensures that the RHA Wireless Flight Adapter is able to support most if not all the Bluetooth headphones and earbuds on the market today. The adapter also supports Bluetooth Codecs aptX, aptX LL, and SBC amongst which aptX LL is the most important to allow low-latency when watching movies on flights.
With only a power button and an LED indicator to facilitate Bluetooth pairing, the pairing process on the RHA Wireless Flight Adapter is surprisingly straightforward. Designed to pair with the closest Bluetooth device, one must first ensure the adapter is switched off before setting the pair of Bluetooth headphones/earbuds to pairing mode. Next, bring the adapter close to the pair Bluetooth headphones/earbuds and press the power button for three seconds or until the LED indicator starts to flash in Blue. When successfully paired, one would hear a pairing tone on the matched pair of Bluetooth headphones or earbuds; the LED indicator will stop flashing and remain in a solidly blue state.
The RHA Wireless Flight Adapter also allows the simultaneous broadcast to two pairs of Bluetooth headphones/earbuds. To do so, one must activate the pairing of the first pair of Bluetooth headphones/earbuds, set the pair of the second pair of Bluetooth headphones/earbuds to pairing mode, then press and release the power button twice to connect the second device. Do note that while the adapter remembers the pairing of the first pair of Bluetooth headphones/earbuds, it does not recognise the second pair once the pair of Bluetooth headphones/earbuds or the adapter is switched off. However, when paired via the primary pairing mode, the adapter remembers up to eight paired devices. It will attempt to reconnect automatically to the pair of Bluetooth headphones/earbuds previously paired.
During the review process, I have brought the adapter with me onboard eight flights, which are a mixture of short-haul and long-haul flights. I am pleased to share that there were no audio distortions or dropped connections experienced. Many a time, the pair of Bluetooth headphones/earbuds ran out of battery before the adapter did. The RHA Wireless Flight Adapter has also reconnected me to the IFE systems. Maybe except for the two flights on Cathay Pacific, where the single 3.5 mm stereo plug could not be securely attached to the aircraft’s single-pronged 3.5 mm stereo jack interface found on the armrest due to the design of the adapter.
