The short version

Buy it if

Older cars with an aux jack but no Bluetooth
Home stereos or powered speakers you want to stream to from a phone
Households where two phones share one car

Skip it if

Your car has no aux input; an FM transmitter is the usual route then
You dislike voice prompts and want a receiver that stays quiet
Call quality matters more to you than music

What owners like

Pairs fast and reconnects reliably
Clear sound with little noticeable lag for music
Battery life close to the 12 hour claim
Small enough to tuck out of sight

Common complaints

A loud disconnect voice prompt plays whenever the car or phone turns off
No battery level indicator or low battery warning
Faint hiss through the speakers when nothing is playing
The aux plug can work loose in tight spaces, and the bundled aux cord feels cheap
Microphone quality for calls is only fair

Based on The Amazon listing, the Anker user manual specifications, a retro car audio review from Retro Tech Drives and a roundup from The Gadget Buyer..

Research scores

Performance 7.0 quick pairing and clean music, but idle hiss and fair call audio

What it does

A small battery powered Bluetooth 5.0 receiver that plugs into a 3.5 mm aux jack so a car stereo, home stereo or wired speaker can play audio from a phone. This page covers it in place of the TaoTronics receiver, which is no longer sold in the US.

Adds Bluetooth audio to any car or home stereo with an aux jack
Pairs with two phones or devices at once
Built in microphone for hands free calls
Three buttons for power and volume
Rechargeable battery, so it can run without a constant power cable

A sensible pick if your car or stereo has an aux input but no Bluetooth and you want hands free calls as well. Reviewers report quick pairing and clean sound, but also a voice prompt every time the car powers off, no low battery warning, and some background hiss when nothing is playing.
