What it does well.

Key features
LDAC, Hi-Res Audio. Higher-quality wireless audio with LDAC-capable phones, plus standard Bluetooth playback for everything else.
Bluetooth 6.0. A stable, low-latency connection between your phone and the receiver.
Hands-free calls. A built-in microphone lets you take calls through the car or speaker audio.
Two phones, 17 hours. Connect two phones at once and switch freely, with up to 17 hours of playback per charge.

Where it fits
Car stereos with AUX. Add Bluetooth music and calls to an older car stereo with a 3.5mm AUX input.
Speakers and hi-fi. Stream to powered speakers, amplifiers or a home system that only has a wired input.
Wired headphones and sharing. Make a pair of wired headphones wireless, or keep two phones connected in a shared car.
Will it work with your setup?
- Needs a 3.5mm AUX input on the car stereo, speaker or amplifier.
- LDAC quality needs a phone that supports LDAC, which many Android phones do. iPhones connect using standard Bluetooth codecs.
- Hands-free calling needs the audio system to stay on the AUX source during the call.
Setup and everyday use
- Charge the receiver fully before first use.
- Plug the receiver into the 3.5mm AUX input and switch the stereo or speaker to AUX.
- Put the receiver into pairing mode and select it in your phone Bluetooth settings.
- On an Android phone that supports LDAC, you can choose LDAC in the Bluetooth device or developer settings.
- Recharge when the battery runs low, using the supplied cable and a USB charger or the car USB port.

A closer look
Before you buy
- The receiver adds Bluetooth to a wired AUX input; it does not work with systems that have no AUX or line input.
- Engine or charging noise in some cars comes from a ground loop; a ground-loop isolator can reduce it if needed.
- Final sound quality also depends on the stereo, speakers and the original music file.
