UGREEN Bluetooth 5.3 Transmitter Receiver, 28H Long Playtime, Dual Connection, 10m Range, Mic for Calls, 2-in-1 Wireless Aux Bluetooth Adapter for TV, Airplane, Headphone, Airpods, Speaker, Car

I must admit, I had my reservations about this device as I always do my research before purchasing hardware and the reviews on Amazon were mixed. However, uGreen has been gaining traction in the tech market over recent years so thought I'd give it a try. For reference, I've had numerous uGreen devices in the past and they are all pretty well made and tend to perform well - this device included. It has a plastic casing with, what feels like, a (1 inch) braided cable to the 3.5mm jack. With the jack cable laid straight, it's around 115mm x 29mm x 11mm. The cable is bendable though, due to how short it is, there's not much play, so I suspect trying to bend it 180 degrees back on itself might eventually cause a break in the cable. It's got a USB-C charging port on the end of the device which, according to the manual, allows you to fully charge the device from zero in 2 hrs. There is a slider switch on the side to change between receive and transmit modes, and a main button on the top which you can use to turn the device on and off (by holding it for three seconds) and also for pairing it to your bluetooth device of choice. Once paired, the light around the main button will intermittently illuminate blue to inform you that it's connected. It's not that distracting though might be a problem for some people who are, for example, listening to music in the dark! It's on for about three seconds then off for about nine. The reason I needed a device like this was for a DAB radio (which was bought for me by my other half, though she didn't realise it only had BT receive capabilities), so that I could listen to it using some BT v5.0 EarFun Air Pro buds. To be fair, this device does a pretty good job considering the price. The sound quality is fairly good, it's easy to setup and use and seems to hold charge fairly well. I haven't used it extensively but I assume the "about 28hr" transmit usage that it states is going to be under peak conditions - i.e. after it's been fully charged straight out of the box and only on a low output volume. As I haven't had this device long, I unfortunately can't confirm this either way though I think it will do what I need it to do. I also can't test all connectivity permutations though it apparently uses SBC codecs for transmit and SBC and AAC for receiving. I've not had any drops as yet, though I have mainly only used it to listen to the football coverage and for around an hour before bed so not really had chance to test how the connectivity is affected when the battery charge depletes. So far so good though! One final point is that I have tried it with my XBox Series X controller while playing Battlefield. I'll put it out there now, it's not perfect. There is a slight latency which I think some hardcore gamers would find challenging. However, I've played it for over an hour and I think it's acceptable. It's all personal preference though - if you're critical about issues like that, it isn't for you, but I personally think it's an acceptable tolerance. All in all, a nice little device. It was around £18 when I bought it so, for me, this is a relatively inexpensive option that gives you BT transmitting and receiving capabilities for your 3.5mm jack devices. : )

As usual, UGREEN has knocked it out of the park with this one. The device is very easy to connect to. I use it to pair my Bluetooth headphones with my PlayStation Portal, and there's no noticeable input lag, which is very important for gaming, so this product is ideal if that's what you're looking for. The sound quality is also excellent, I didn't notice any degredation in the sound of my headphones when compared to a standard connection to my phone. There is a very slight hissing noise, but this is only noticeable when there's no other sound being played, so it doesn't bother me. Overall, this is a great product. I've tried a few Bluetooth transmitters that were cheaper than this, and none of them worked properly. I'd say go ahead and buy this UGREEN one if you want something reliable and well made.

This Bluetooth Transmitter and Receiver has become a highly valuable piece of tech in my setup. The core performance is excellent - the audio is consistently clear, whether I'm using it to stream music to my speakers or utilizing the integrated microphone for calls. I've easily connected it to both my high-quality wireless headphones and a larger stereo system, and the pairing process was simple and reliable every time. ​The integrated microphone is a great feature, producing clear voice capture when needed. ​The only real downside I've encountered is the battery life when using it in transmit mode (TX). It seems to drain much faster than in receiver mode (RX), meaning I often need to keep it plugged in or near a charging source for longer sessions. If you plan to use it mostly as a transmitter for long periods, be aware of this limitation. Overall, the audio quality and versatility make it a worthwhile purchase!

This is a great little item that was easy to use and connect to my phone via Bluetooth. It brought back life to my old stereo and with it being small in size it hides itself well. Playing music through it i haven't experienced al any lag or delays and its battery life lasts quite a while too but works better if you can have it permanently charging via its usb. Only down side and it is a small thing if you forget to turn it off after using your phone it will stay connected to it until you remember to disconnect or stitch off.

One button on a device like this doesn't work if you want to use it with multipe devices. I want to use it with my Anker sleep buds at night, my Shokz when running and my over ear headphones during the day. One button to turn it on/off and do pairing is just a poor ux. Also... the CONSTANT flashing of the light. There is no need! I want to use this at night, but the light is always flashing, either blue when paired, red and blue when in pairing mode or red/green when charging. The whole device is just poorly executed. I'm going to get an AirFly which has no flashing light, and dedicated buttons for the desired functionality.

Having bought various quality UGREEN Chargers I tried both this UGREEN and the Avantree Relay and at HALF the price this is superb. Just as high quality and works brilliantly with my Sony WH-1000XM4 to connect Bluetooth to PlayStation Portal. Neat solution with a small bit of velcro tape. Reccomend!

Works really well, and is well made it's just the latency is too high. Probably half a second, max. So for instance, explosion happens on film and you hear it half a second later. It's a shame, ive tried it with many other devices and it's the same. Very easy to connect though. Nearly an excellent game changing product.

Easy to set up. I have used it for headphones for my xbox, audio out from a hi-fi and audio in to the hifi. Very versatile and reasonably priced for what it can do. I was also pleased to find it remembers quite a few settings so I can swap from hook up to another without problem. There can be a slight delay (latency) on some applications but not really a problem for me. Battery life is good also. Recommend.
