UGREEN Bluetooth 5.2 Transmitter For TV, Dual Pair Wireless Bluetooth Transmitter Receiver compatible with Airpods Earbuds Speaker, Bluetooth Headphone Adapter For Airplane, TV Audio, PC, MP3, and Gym

I’ve tested this in both transmit and receive modes and both work with minimal lag (Bluetooth is inherently laggy). Using VLC, Voicemeeter, and outputting to a set of Edifier speakers using Bluetooth and another directly hooked up to the audio source I found the lag to be around 20ms. That’s pretty good.One of the most useful features for me is being able to connect and transmit to two different devices at the same time. I imagine most people would use it so two people can listen to the same audio at the same time in Bluetooth headsets but I’m using it to transmit to two distinct sets of Edifier speakers in two different rooms so I can walk from my office to my house without having to mess with changing audio sources (I can hear my office from my house and vice versa, just not loud enough).To my delight it took all of about a five minute to set up both sets of speakers and have them outputting synchronized audio, the majority of the time being walking back and forth to test.The range of the transmitter is beyond impressive; I’m able to walk about 100 feet from my office to my house with my phone (where I play all my music and podcasts from) and it never loses connectivity. That’s pretty impressive for something so small.In that receive mode I tested outputting from my Android phone and one of my iPads and both worked perfectly. When paired with one device in receive mode the UGreen device would refuse to go into pairing mode so it smartly keeps me from having multiple receive devices paired at once. To get the UGreen receiver to pair with a new device I had to have that device either forget the receiver or turn off Bluetooth so keep that in mind if you’re switching back and forth between Bluetooth devices.But wait! There’s more! It’s also got a battery in it so after charging it up you can walk around with it receiving or transmitting! This thing is amazing, if I could give it ten stars I would.

Sound quality is very good on this device, both transmitting and receiving. I generally use this to send music out from an older style mp3 player/voice recorder and from a radio over bluetooth to speakers and headphones. In all cases, this one sounds very good no matter the input volume level, which up until very recently was very hard to find. I also tested this paired to a phone, and the music going into my wired speakers and headphones also sounds very good and clear. In this receiving mode, it also includes a built-in mic for making phone calls. In my tests, I found the quality of phone calls to be very good, and calling other mobile phones gives me a very clear voice in both directions. I do have a transmitter and receiver that is smaller than this, but it will not receive phone call audio and allow me to talk through it. This one does this, making it the best one I have used so far. I also like the battery life, which is good enough to run all day and more without needing to be recharged. Add to this the RCA plugs, the 3.5mm audio cable and the very small 3.5mm plug with no cable and you get an all-around 5-star product that is well worth its price.

When I received the package I was surprised by the size. I knew it would be smaller but this is very small. Maybe an inch and a half square so it’s easy to hide behind TV. Or even if it’s in the front of a stereo, it doesn’t stick out very far. I originally bought this to listen to an old TV with headphones so I wouldn’t bother people while sleeping. I since found myself using it more as a receiver and streaming music from my phone to my old stereo with larger speakers that sound much better than any Bluetooth speaker I own. It’s very easy to use and comes with multiple cords for easy connection in many different scenarios. It paired up quickly and seems to stream very well for me. Farthest range I have go is about 20 ft and never had a dropout. This is turned out to be a much more useful product and I originally thought it would be. I would almost think of buying another, but it is so small and portable and easy to set up that it is just easy to move it from place to place. Being battery powered, there’s nothing to plug in for power cord so this is a good product to use on multiple devices.

The bluetooth transmitter work great. It allows me to use my air pods while working on my computer when im not driving. Connection is flawless and no lagging at all. I like that I have this device to take with me next time I have to fly out. The device is small and easy to carry with you. Several adapters are included, giving you options on connecting in various ways. Great product to own overall.

This bluetooth receiver is simple to operate and quite reliable. While testing it out, I never had any issues connecting to it or with the signal dropping. I really liked how many connection options it comes with; RCA cable, aux cable, and headphone jack. I haven’t tested out it’s overall battery duration but without a screen or many indicator lights, I’m hoping a single charge will last quite a while. Also, I like how small and portable it is; it’s about an inch and a half square.The most important aspect is the sound that is produced and I must say that it was great; it sounded like I was listening to the music through high-quality earphones. Now, the sound definitely depends on the device you’re using but it will not be negatively impacted by this receiver, I assure you. I would definitely recommend this bluetooth audio receiver.
