Golvery Upgraded Bluetooth 5.4 Receiver for Speaker, Wireless Audio Adapter for Home Audio Car Stereo with 3.5mm RCA Jack, 20 Hours Playtime, Dual Connection to 2 Phones, Easy Control ON/Off Slider

Inexpensive but quality product. Works very well.

I was hesitant because every other option I've tried to integrate Bluetooth into my '08 Infiniti G35 has proven null. I tried the radio Bluetooth transponder but living in the cities, it gets squashed frequently and is frustrating trying to change while driving. The audio quality of those also sucks. I tried an adapter, didn't work. Finally tried this and...thank god it worked perfectly. I no longer have to worry about radio channels flipping going in and out of the city, just connects right to my aux. And the sound of this is super crisp!I really like the fact that I can leave this plugged into my cigarette port (with USB connecter) and never have to worry about charging it. I just start my car, my phone auto connects to the car for calling, connects to this for music, and boom, music is ready to go. It's fantastic and it's so small! Literally, there are 2 buttons on this thing, it's so easy to figure out. The instructions also say that after 5 min this will turn off if you've disconnected your phone so there's no worry about it sucking the battery from your car. I have yet to notice any problems.A fantastic little gadget for those who have a slightly older car!

Another super little device from Golvery and great Hi-Fi sound with multi-purpose applicationsEverything I have bought from Golvery has been of the highest quality and great value for money.This mini portable bluetooth V4.1 audio receiver is again high quality and great value. Really love this product! After recently buying an iPhone 7, I could no longer play music through an aux cord in my car, so bought this as an alternative.Meanwhile it is really useful for me to be able to play music on my hifi speakers without using a wire, thus avoided the tripping hazard!Sound quality is excellent, with an almost imperceptible drop compared to a wired connection. The controls are easy to use even whilst attached to the headphones.1)The goods arrived very quickly and Absolutely perfect package.2)Easy to use as the user manual and simple and very fast to pair and connect my iPhone and the audio output is very good.3)It has one slide switch and puss it for power on/off, compact design. When disconnect, the item can be auto power off within bit minutes to save power.4)It automatically reconnect the paired devices quickly.5)Support Multi-point connection.The bluetooth paired immediately and the second device pairing was no hassle at all.6)Quite good bluetooth range, I can walk around a fair bit of the house and the music will still play.7)The battery life is amazing – over 12 hours when always playing.In short, excellent service and great product, very nice to be pro-actively contacted by the seller to ensure everything was to my satisfaction.

This Bluetooth wireless adapter will work great for portable speakers or any mini-stereo input jack. It can be charged via USB-C for portable use.If you want to use it for your car stereo be aware that it may suffer from ground loop interference. You’ll hear a high-pitched whine synced with your car’s RPMs when the volume is high. So to use it in your car you should also buy this:https://a.co/d/dW2cZbtIt’s a ground loop eliminator and it works perfectly with this Bluetooth adapter. And it only costs $8.

Does exactly what it says. Easy to plug in and pair my phone to an old stereo that only has red/blue connections.

My 2014 truck does not have a bluetooth enabled stereo which I can stream music from my phone. I have previously been using an adapter that takes the bluetooth signal and transmits it through radio frequency to the stereo. That adapter works, but the sound quality is degraded and the radio picks up interference when not tuned to the specific frequency so that the adapter must be unplugged in order to listen to the radio. Since my radio has an RCA plug, I thought I would try this unit instead and I'm glad I did. It works wonderfully. Its TINY!! There is an on/off switch on the side and a play/pause button in the front. . . that's it. No degraded sound quality through the RCA plug. It can also be plugged in to a USB adapter while playing to keep it charged. Its small, it's cheap, it works, what's not to love about that.

Bought this for our houses built in speaker system. The box was older though so I bought this to play bluetooth via my phone. It works great. No issues so far. I keep it plugged in to charge it and it stays hooked into the speaker box. Easy to connect and disconnect. I can also use my phone in the kitchen and keep the receiver in the living room with no problems.

I bought one of these and thought that it was great so I bought two more. So far of the three that I purchase, two of them have died. They were connected to stereo systems inside the house. I swapped them out with the one that works and was able to verify that two of them were in fact dead. I tried with multiple phones and on multiple stereos and they would not work. When I would go to the one that did work, it worked fine on all stereos and with all phones.vI bought one of these and thought that it was great so I bought two more.

Not only did I lose money, but it also created a huge problem hours before a big party at our house.
