What it is and who it's for

This ALSEYE 2 in 1 accessory is a Bluetooth 5.3 transmitter and receiver that adds wireless audio to any device with a 3.5 mm aux jack. It suits travellers who want to use their own headphones on aircraft seat-back systems or gym equipment, and home users who wish to stream TV sound to Bluetooth headsets without replacing the source device.

Practical limits of the Bluetooth 5.3 link

The adapter pairs automatically with compatible headphones within an eight metre range and supports aptX Low Latency, aptX and SBC codecs for stable transmission. Audio quality and latency depend on the source device also supporting Bluetooth 5.3 and the chosen codec; older Bluetooth versions will fall back to SBC and may introduce noticeable delay or reduced fidelity.

Deciding specification: 15 hour battery life

A single charge delivers more than 15 hours of continuous use, enough for most long-haul flights or extended viewing sessions. If the battery runs flat the included USB-C cable allows charging while the adapter remains in operation, so playback does not need to stop. Buyers who need multi-day operation without access to a USB power source should look for a larger-capacity alternative.
