UGREEN Bluetooth Transmitter Receiver for 2 AirPods or BT Devices, Bluetooth Wireless Transmitter for Headphones, 3.5mm Aux Audio Jack Adapter for in-Flight TV Car Home Stereo System

I use this with a portable police scanner and BT headphones. Works flawlessly! Battery life is great, easy to use and setup. I have also used this in my car to listen to my scanner through the stereo speakers, worked great in that instance too.

I purchased the UGreen Bluetooth Audio Receiver & Transmitter for my Zune HD. I used this Zune just about everyday from the day I purchased it 2010 and I have faithfully found a way to violently tug the headphone cord causing it to be jerked out of the Zune or the Zune hitting the floor. When I want to use it with my JBL speaker, I would have to connect it with the audio cord and struggle to find a safe place to set them both up. I have gotten tired of the Zune HD hitting the floor more times than the JBL speaker. My Zune HD still works perfectly, so I felt it was time to treat it right and make it a Bluetooth device to help keep it safe. The hardest part was figuring out what setting to use TX or RX and then pairing it with the JBL speaker without reading the included instruction manual I misplaced. THE ANSWER: TX , press the power button for 3 seconds then turn on the Bluetooth speaker or headphones. The sound to my speaker sounds as if it's connected via the audio cord. The transmitter doesn't feel like it added any extra weight to my Zune HD. When I got tugged and hit the transmitter the black rubber part before the audio plug moves. It does not feel like there is any extra trauma being caused to the Zune's audio jack like when I get the headphone cords tugged. While it was connected to my JBL Charge 3 speaker, I pressed the pause button and it did not pause the music on the Zune, so I guess the controls don't work. I have a pair of XO Beach 3D headphones that I love and this would not connect to them. I only received this 1 hour before this review so I will have to test out other headphones they can and cannot connect to.

Works great with AirPods, had them working within literal seconds. However I purchased these as an attempt to wirelessly transmit my instruments into my AirPods. And when I attempted to play the delay in audio simply made playing impossible. I would gladly pay three or four times for a device that dealt with that issue (and in fairness most devices that do that are 12X the price). Other than that outstanding.

Bluetooth has lag and is inherently less high quality than a wired connection. Them's the brakes with Bluetooth. However, that being said, this one is a particularly bad example. The audio sounds like it is being played through the telephone. The lag is ALWAYS at least over one second so if you were planning on using this for anything more than just beaming over music, you will not have a good experience. For me, this lag is incredibly poor. Video watching was going to be my main use for this thing, but having lag just makes it nigh-unwatchable. Not all devices support shifting the audio to fix my issue, either. But I should not have to do that at all. When it comes to battery life, the manual says it lasts 5.5 hours. Wish it lasted longer, especially for a device being sold in 2023. But whatever, It's a small device. That can't really be helped. But one of the worst things is the awful voice used. I get that they have to give you SOME kind of indication that devices are paired (even though the light on the device can and WILL do the same thing). It's not so much that the voice is unpleasant, it's just that it is SO. DANG. LOUD. It will blast "POWER ON", and "BLUETOOTH CONNECTED" into your ears at full volume. Make sure to put on your headphones AFTER you have turned the device on. AWFUL, AWFUL idea. They do give you the option to change the voice. Only issue is the only other option is Chinese. An option to completely remove the voice would improve this product. What a disappointment this product ended up being, especially with the other reviews praising it. Considering how amazingly good those other reviews are, I almost wonder if I just got a borked unit.

I use these to listen to music while flying a jet through a Bose headset. Also into a old stereo using an adapter. Great product.

I was trying to use this unit as a transmitter for my guitar amplifier. In this application there cannot be any delay. However, once I got it working I found about a half second delay which just doesn’t work. I don’t know if that would apply to a TV watching situation because I didn’t try it but I would assume that would be the same issue. To start, it was extremely difficult to pair this unit. I was trying to pair with Apple AirPods Pro. I almost gave up. The directions are clear but didn’t work and need more troubleshooting details. I’ll provide a few. First, MAKE SURE ALL BLUETOOTH DEVICES NEARBY ARE OFF. I had turned off my iPad and iPhone but forgot about my Bluetooth keyboard. As a result, unknown to me, the device paired with my keyboard before it had a chance to pair with my AirPods. Once I realized that I followed the directions to reset the unit. They didn’t work. The unit would not reset. After an hour of trying I was about to give up when I had a brainstorm and decided to plug the unit into the power cable. Voila! The unit reset. Once I reset it I was able to easily pair it. UGreen should provide this information. Instead their support is still emailing me questions about where I bought it and then after I provided that information they asked me a question 48 hours later which model I had. You’d think they would ask all their questions at once! Once they were paired they worked well and sounded good. But the delay made it impossible to use. Imagine strumming a guitar and getting the sound a half second later. Can’t use them. I’m back to my wired headphones which have no delay. If the same thing happens with a movie that would drive me crazy. I’m returning the unit.

Serviu perfeitamente. Funcionou em qualquer aparelho, tanto antigos como novos. Testei com um fone de ouvido bluetooth da xiaomi (Redmi Buds 6 Play) e deu certo. Não pareia de primeira mas nos testes que fiz funcionou sempre.

Seamless and easy to connect with any audio device which doesn't have a Bluetooth connection. There is no lag and output seems to be good enough. Its small and compact and the battery life is also fair enough.

Fonctionne super bien et facile à connecter !

Pairing tip: (was required for pairing my Airpods Pro 1): after turning on the device (blue light), do a short double press to get device into pairing mode (blue-red flashing light). Overall; some trouble with pairing at first and manual was not very clear. good quality and price. I was very happy with the item when I used it for the in-flight entertainment system on an airplane.
