Golvery Bluetooth 5.4 Receiver, Hifi Wireless Audio Adapter for Car/Speaker

Paired it with iPhone 12. Connected old pair of wired 3.5mm Apple headphones. Was amazed at the quality of sound. Unit is surprisingly small and light. Given my headphones a whole new life. Manufacturers claim 20 hour battery life between charges. Great product so far.

Graleat product, turned my old car radio into a top of the range bluetooth. Saved me a fortune and sound quality is excellent

Very impressed with this. We were able to stream Spotify to an older internet radio as it had audio in which works well with this unit. You can also turn the volume up and down and change the track. It is very small so doesn’t take up a lot of space.

Quick to connect and just works whether with car, powered speakers or hi-fi system. Small and compact and no loss in sound quality. No phono plugs. Just comes with 3.5mm male-male jacks and a USB-C cable for charging

The sound quality seemed decent, but due to the battery it does not turn itself on/off with the car. It would keep playing upon shutting the car off, then would bizarrely pause when i restarted it. Even keeping the battery, this could be fixed with software in a future version, but as it stands the way it works was a dealbreker for me so returned it.

This has dramatically changed bluetooth phone calls from my car; I cannot recommend it enough for that attribute alone and can't complain about its audio performance either. My previous bluetooth FM transmitter was equally good for audio performance but was terrible for phone calls.

The sound quality was mono and dreadful. I returned it.

Simple little package, very lightweight so adds practically nothing weight wise. Small issue to start but excellent proactive communication from the seller

Few if any other bluetooth receivers in this price range can drive a pillow speaker or low power headphones. This one can. My C. Crane unpowered pillow speaker has great sound. I've been using them for decades. The J207 drives it with plenty of volume and good fidelity. The receiver lives on my headboard, so I leave it plugged in to a charger. The instructions warn that a ground loop blocker might be needed in that configuration, but my setup works fine without it. And it's tiny!

I'm absolutely thrilled with this Bluetooth adapter! It has everything I wanted and more. The sound quality is top-notch, whether I use it with my vintage home stereo or in the car. The upgrade to Bluetooth 5.3 technology is a game-changer. It's been super reliable, haven’t had any issues connecting to my devices. The battery charges fast and lasts about 20 hours, so I don't have to worry about recharging it all the time, but in the car I just keep it plugged in with the usb adapter. And let me tell you, it's so easy to use! I paired it in a snap and it automatically connects every time. The best part? It's a great value for the price. It does everything I need it to do without a hitch and delivers fantastic sound. I highly recommend it!

Receiver was easy to connect to my phone's bluetooth and I added a little piece of velcro to stick it to my dash. I also keep it connected to a car charging cable. Keeping it connected to a power source not only ensures it will always be charged, it also connects to my phone automatically once I start the car! I had a different receive that broke and bought this one to replace it and this one works way better! No lag and the button interface is super easy to control without having to look where you're placing your finger so you can keep your eyes on the road!

I specifically bought this model for increased range, and it really delivered. I rarely write a review, but one day this really surprised me. I had left my phone charging at work one time, and had to visit another one of our buildings about 200 feet away. When i entered the other building I went to reach for my phone and realized I did not have it with me, but since my headphones were still receiving the should without any distortion, I did not realize I did not have my phone with me. Normally distorted sound in my headphones is a key indicator when I leave my phone behind, so this can almost be a bad thing lol. That type of range is not always consistent, I'm not sure what conditions caused that fluke, but within 50 feet I have rarely experienced any signal loss regardless of line of site conditions.

Truly a plug and play device. It is about as simple as turning on a light. Highly recommended.
