Bluetooth 5.3 Adapter 3.5mm Jack Aux Dongle, 2-in-1 Bluetooth Transmitter Receiver for Car Audio/Home Stereo/Headphones/Speaker/Projector...

This is great for my car which doesnt have bluetooth for music. Charged it, paired it with my phon (device c28), plugged into my audio jack in the console and now I play my ZeeBooth Music through the car sound system.

I use this to play audio from my phone to an old stereo in my garage with a 3.5mm "audio in" port. It works great. Battery lasts at least a few hours, which is enough. I also used it in TX mode to send audio from a laptop to a bluetooth speaker. Simply plugged it in to the laptop headphone jack. To my surprise It connected to the bluetooth speaker automatically and with no issues.

I ordered this so I could use my elderly MP3 player (don't laugh, I love that thing) with Bluetooth devices, especially my motorcycle helmet. I received it, charged it, and brought it with me to work in my car to test out. I powered it on and tried to get it to sync with my car's entertainment system. The entertainment system recognized it but wouldn't sync no matter what. I tried it a few more times in both transmit (TX) and receive (RX) mode, all to no avail. Thinking that my car's entertainment system might be a bit finicky (it has been in the past), I also tried to pair it with my laptop. This laptop recognizes EVERYTHING that's Bluetooth-equipped in a 50 foot radius-- my mouse, my wireless headset, everyone else's wireless headsets, you name it. Everything, that is, except this transmitter. Like two awkward adolescents at a middle-school dance, my computer and the transmitter refused to acknowledge one another's existence. I tried again with my phone, an older Samsung that will pair with just about anything including a set of convenience-store earbuds that are notoriously finicky. Nothing. My phone didn't even see this thing. It also acts flaky. Sometimes it refuses to turn off even if I hold the power button down for 10 seconds or more. Yesterday I spent the entire day charging it so that I could try syncing it one last time on my ride home. When I unplugged it from the charger it turned itself on and would not shut back off despite me holding down the power button for 20 seconds at a time. I guess the battery ran down overnight because it was off this morning. I have another Bluetooth transmitter that I bought a couple of years back and ended up not using. Truth be told, I completely forgot I had it when I ordered this one. The older transmitter, a Taotronics unit that no longer has a listing on ZeeBooth, paired immediately with my car and worked perfectly. At this point I knew that this transmitter was a dud. If you buy this, be aware that the build quality looks mediocre at best. This wouldn't be a problem if the thing actually worked, but mine at least was a complete waste of time. I spent three days trying to get this thing to work on several different devices and had zero success. It didn't transmit a single note of music. I strongly recommend you buy something better even if it costs a little more. This one is going back to ZeeBooth.

when I purchased this (May 2024), there were two options to chose from and I personally have no idea what the difference is between the two. I selected the one with physical buttons on it for literally no other reason that it had buttons lol. As for the item itself, I purchased this so I could use my Bluetooth headphones on my work computer. I could only use my wired headphones but we all know how annoyingly in the way wires can be. So I opted for this and it was surprisingly simple to use. I turned the device on to TX mode, set my headphones to pairing mode and waited a few seconds and it paired no problem. Sound quality is good, no static unless I touch the transmitter which is perfect because once it's plugged in there is really no reason to touch it again. I also like that it is small and easy to move around. My only complaint is that it doesnt have some sort of carrying pouch or something to keep it all together, I wont dock a star for this, it just would have been a nice addition to help keep everything together. Plus, it was only $10 so I cant be too picky. I plan on using this while traveling as well since I can never use my BT headphones on the planes but now with the transmitter, that problem should be solved!

This was crazy easy to set up, connects automatically when turned on, you can pair multiple devices and it'll automatically connect to whichever devices Bluetooth settings is on when you hop in. When it dies I just plug it right into my car charger and it works immediately while plugged in! I have an older car without the Bluetooth function and this little thing works super easy and sounds amazing! I was conflicted after reading many reviews but it sounds clear, definitely gives an old car that Bluetooth features, it's easy to set up and connect afterwards, works while charging, you can pair multiple devices which makes it just as convenient when my significant other needs to use it.. there's really no downside, I absolutely love this thing and I fully expected to deal with some inconveniences but no it is perfect and works very well!
