UGREENAirplane Bluetooth 5.4 Transmitter Receiver for 2 Airpods or Headphones, Airplane Travel Essentials 2-in-1 Wireless Bluetooth Adapter, 3.5MM AUX Jack Adapter on Flight, TV, Car Stereo

So far, I love this bluetooth transmitter / receiver. The sound is crystal clear and its very easy to pair with multiple different devices; wireless headphones, wireless earbuds, and iPhone for playinig with car stereo. Its compact but not too small. Easily fits in the case with wireless headphones. Will hook up to home stereo next for testing sound quality. I purchased this for an upcoming long flight for movies. One review noted a delay in sound from transmitter not synching with video on screen. I did not notice this delay when testing by playing video on laptop, but can circle back after using on the plane. So far I highly recommend this device.

I did not know you could not increase the volume or decrease the volume when you have it up to the TV have not tried it on my phone yet we'll get back to it later

Great product! Worked so well and easy to step up and use. Had a little trouble initially setting up but that was because I didn’t take the instructions with me but that’s on me! Set up in a couple of minutes and good to work for our 6 hour flight with no issue

(Updated after using the product for two days. Reduced overall rating by 1 Star and added more CONS.) I wear Bluetooth (BT) enabled hearing aids. I bought this as a travel capable BT adapter to allow me to quickly connect to almost any audio device. PROS: It works as advertised. Easily paired to my hearing aids. Charges correctly. CON: I tested it using my Samsung laptop's audio jack with the internal BT off. It has a CONSTANT and ANNOYING WHITE NOISE output whether connected to a source or not!!! (Regular headphones, plugged into the same jack, lack this noise.) [The white noise faded after 6 hours of use.] It has random sound glitches missing from my headphones when playing the same audio. Must be REPAIRED every time you cycle off/on power, which pretty much cancels my reason for buying it. ADVISORIES: (Just so you know) 1. It lacks the airplane adapter provided by most products like this. I knew this before purchase but I already had the adapter. 2. It lacks a carrying bag which it needs to keep the device and accessories together and protected while carrying. Again, I knew this before purchase and had one I could use. To be fair, the only BT dongle I've used is connected to my TV and it has NO WHITE NOISE! THE BIG PROBLEM IS THE CONSTANT NOISE!!! I've purchased other UGREENI products and have never been disappointed until now. I really can't recommend this item. I'm sorry I purchased it.

I got this because I wanted to upgrade from a cheaper one with bad battery life, and I had no idea how bad that one was until I got this one. The battery lasts so much longer, and the sound is so much better. It seems to be built fairly well and I haven't had any problems with it in the few weeks I've had it.

Works as described. Didn't notice lag in audio quality. Set up is a little tricky but can be achieved, wish there are video instructions to set up. It does not remember the device connected, you need to pair your AirPods every time you want to connect like a new device.

Worked great for connecting my iPod classic to my AirPod pros. Now I can listen to my old music wire free. And battery life is excellent. Took two 4 hour flights, still haven’t charged it.

In transmitter mode there is a noticeable lag, not quite but approaching a second. When watching a movie, it's a very noticeable delay and definitely takes away from the experience. It connects easily and reliably, is lightweight, and holds a charge, but those are not unique benefits compared to competitors and does not overcome the lagging sound. I'd look elsewhere unless this is on super sale. This is extra disappointing since my experiences with UGREEN products have generally been positive.
