Bluetooth Adaptor AUX Car Bluetooth Receiver 4.1

Used in the car aux system, connected to iPhone by bluetooth, gives clear sound in the car audio system, there is no sound interference at all, as this is not FM transmitter. If on a call, the other party voice can be heard in the car audio system, volume can be controlled with the car audio tuner, our voice is caught by the mic in this device, works well. Hope this device lasts longer. Good battery life. Happy with the product..

This is best I have used so far in the same form factor. Easy to use and set up and no distortion or disconnection when in use. Button placement and charging port at the bottom makes it very convenient for use. I am using it for my old car that has AUX in and previously using FM transmitter. This is so much better with better quality. Though I wish they will come up with bluetooth 5.0 version in the future. This product is affordable and nicely built. Only issue I have is that if this product turned off when disconnecting from the AUX cable automatically then it would be perfect but at this point I am just being fussy. As for calls the microphone is decent but not amazing, placement of the device makes a difference therefore if it is bit far from you and the car is noisy, person on the other side of the call will hear a lot of noise. Overall excellent product, especially considering the price and I just leave it connected in my car. Definitely recommend it over FM transmitter and other overpriced product.

If your car doesn’t have inbuilt Bluetooth then you can use it by connecting your phone to it. And it can be connected to aux port in f your car Pros 1. Good sound while playing music 2. Battery life is also good. (You can still plug in to charger also) Cons: 1. While calling sound is little less 2. Also we need to speak little louder for other person to hear your voice( in my car aux port is between the seats inside the storage, may be that’s why)

Just you have to charge it every couple of days

Pros: Very simple to connect, battery lasts a while, and the connection is quite strong whenever paired with, I would still buy this again nearly 4 years later. Cons: Built in microphone is not that great, it does not let people hear me clearly 90% of the time and I often had to change to speakerphone and using the phones microphone to bypass it, however to be frank that did not feel like too much effort. TL;DR Still worth in 2025 overall

If your car doesn't have Bluetooth capability, this item is a must have for wireless music streaming in your car or home. The sound quality compared to other similar products is so much better. Amazing clarity. The microphone for the call quality sometimes doesn't pick up my voice that well as the party on the other end finds it difficult hearing me (sometimes only). But otherwise, music quality-wise, I would give it a 100/100. Happy with the product.

Using since 3 years still working good

Clear sound and compact design, only problem is battery life
