Been using for close to a year connect to my sound bar very easily works really well and I have zero complaints

works great no issues

The directions weren’t super intuitive, but it was easy enough to figure out. The tiny little invisible TX button was on the side of the unit. Once I found that I was good. But my son has been using it for his new Bluetooth gaming chair since Christmas with no issues.

Wouldn't pair with my headphones.

This replaced a rechargeable transmitter that even when charged would go in and out. This item is fantastic: no lag, clear sound, no outages!

This unit was unusable as the device had a lot of static and crackling noise while connected.

Very pleased with this blue tooth tx rx. I have this connected to a vintage pioneer receiver in transmit mode to connect with anker portable speaker. Well worth the money no complaints.

I always like to start with the positives. This device has a great form factor. It looks like a piece of credible audio gear, it is not molded into some bizarre shape. It is small. Controls are logically laid out. Manual very brief, sparse even, but very complete and written to be understandable in English. Connected to my bluetooth speaker right away, although I did have to turn off the bluetooth on my phone as it was previously paired; this is understandable, I've had to do that with bluetooth devices in many settings. All these things are very impressive and underscore why I wanted to like this device very much.But then I heard it. Very distorted audio, as if the gain was turned too high; overmodulation distortion, not just a floor of noise from the device itself or the audio source. Unlistenable. Would never use this device.I intended to employ it in transmit mode so I could cast audio from my main stereo system (the one with the turntable, CD deck, tape decks, etc.) to various bluetooth speakers around the house. So to test, I connected the line out from a Blu-Ray player directly into this bluetooth transmitter. I played a CD, and heard the overmodulation distortion that I referred to above...the distortion that results from an audio source with too much gain somewhere in the audio chain.To verify that the problem was with the bluetooth transmitter itself, I routed the audio into my bluetooth speaker's aux audio input with a cable. No distortion. Switching back and forth between the bluetooth connection and the wired aux in connection yielded the same result each time, so I know the distortion comes from the bluetooth transmitter, not my disc player (which I already knew since I've had that player for a long time, know it very well, and know that it has never had this distortion).The only way I can think of that I might have tried to abate this problem is to add some kind of attenuation between my disc player and the bluetooth transmitter's line input, but I shouldn't have to do that. The line input should operate at the correct voltage without anyone having to Rube Goldberg a volume control or resistor network between another line out device and this device's line input. Too much effort, too janky, and no guarantee that would even work quite right either, it's just a theory as to the source of the overmodulation.I am very disappointed and returning this device after ten or fifteen minutes of testing because at the end of the day, it is an audio device. It needs to sound good. The fact that it gets the other features right that I mentioned in the first paragraph explain why I am so disappointed; I really wanted to like this unit. It looks so much better and is easier to use than the bluetooth transmitter I have at the small podcast studio where I work. That one is confusing to pair, has just one indicator light that will glow different colors and flash at different rates to indicate status, which is also confusing...but once you've got it connected, it sounds great. If I could have that audio quality with this device's ease of use, we'd have a five-star device here. I was influenced by the previous five-star reviews in fact, and would have heartily agreed if this device actually sounded good (I can't imagine what those reviewers heard, I don't think they're listening very closely). But when audio gear fails in the audio department, that's pretty much a total fail, no matter how good it looks or easy it is to use. This is why it earns one star. I can't keep this device, nor do I recommend that you purchase it.
