## Before you buy

- Bluetooth version claims conflict: the title and details say Bluetooth 6.0, while feature text says Bluetooth 5.4. The title advertises 18 hours overall, but the mode-specific claim is 16 hours transmitting and 18 hours receiving. Compatibility wording lists AirPods Pro/Max broadly, while another note excludes AirPods Pro 2, AirPods 4 and AirPods 4 ANC2. Check the required version and headphone compatibility before buying. The listing also says the adapter is not compatible with musical instruments and is not recommended for guitar or piano use.

## A good fit for

- People who need a compact AUX-to-Bluetooth link for headphones or a Bluetooth-to-AUX link for a car stereo, TV or other audio equipment.
- Travellers who want a battery-powered adapter and can use the listed 3.5mm AUX connection.

## Less suited to

- Musicians seeking an adapter for guitar, piano or performance equipment.
- Buyers who require a confirmed Bluetooth version or guaranteed compatibility with AirPods Pro 2, AirPods 4 or AirPods 4 ANC2.
