This product's small size and ease of use really sold me on it comparatively. I bought it to attach to my New Nintendo 2DS XL, and it fits nicely on the back without getting in the way. Earbuds connect to it without issue, much faster than I expected. Audio quality is great and I don't notice any latency or background noise. The ability to connect two devices at once is great, and it's amazing for systems that don't support Bluetooth transmission. I actually sort of wish the AUX cord was shorter or had right angled ends, but that's something I can buy on my own. Comes with everything you need, and does everything it advertises!

It does work with Airpods Pro Gen 2. See another review for the steps to make it work. I have wanted to be able to listen to movies and concerts transmitted from my audio/video receiver to my airpods for a long time. I have my TV sound coming from my Denon receiver. I just plug this device into the headphone jack on the receiver, follow the other review's steps, and the sound is wonderful, with no noticeable latency. I used to have to run a long headphone extension cord from the receiver to my bulky (but great sounding) Grado headphones. But now, with the Airpods pro gen 2 and this device in transmit mode, no more cable, and the sound is excellent.

As I am sure is the case with many, I purchased this after seeing it listed by the New York Times in their portable BT transmitter review list. It was bought specifically to allow me to transmit BT audio from my computer to my Sony WF-1000XM3 earbuds. As the Sony earbuds only support SBC with these, I wasn't expecting stellar audio quality - I usually use them for lectures or podcast-like content, or for fairly low-bitrate music anyway. I wanted to see if the advantages of true-wireless earbuds were worth the sacrifice in quality before I invested in a more expensive BT transmitter and BT receiver+high-end IEMs. As such, I do not use the receive function, and I do not use the battery on the unit - it is always plugged in via USB. I did briefly test the battery though and can confirm it lasts at least 30m.Note: I went with this type unit, instead of USB, because I wanted to have the ability to test it in multiple environments, including while running and in the car for single-ear usage. Normally, I'd go with a USB solution for computer use in order to avoid the conversion of the audio to and back from analog.Initial SetupDead simple - I connected the Line Out on my computer to the input on the transmitter, and alternately, the HP (headphones) out on my stereo receiver to the input on the transmitter. I also tried it with a Sansa Clip+ MP3 player. It worked in all cases, though with the WF-1000XM3 I had to keep the input volume on the BT transmitter under 30% and allow the headphones to do the real amplification, as otherwise the audio would distort.BT SetupFairly simple. I put my earbuds into pairing mode, the transmitter into pairing mode, and they connected within 10s. Afterward, they maintained their connection for the most part, I've had to re-pair a couple times over the last three weeks, but that is mostly a learning curve. Re-pairing is easy - just hold the pairing button down for two seconds and place the receiving device in pairing mode.RangeUnpredictable, and sensitive. If the transmitter is located on a desk, at least twelve inches away from other electronics, then the range is remarkable. I can leave the room, pass through the adjacent room, and enter into the next room - a total of maybe thirty feet, through two or three walls - and start to lose audio at the end. This is despite being only five feet from a wireless router. However, if I move the transmitter six inches over so it is next to my monitor, or a couple feet so that it is within three feet of the router, the earbuds will begin to drop out even at ten feet. So it is very sensitive to environment.Audio QualityDecent. Better than I expected, but I haven't used bluetooth audio in ten years. It can be hard to really gauge it, because the Sony WF-1000XM3 are true wireless earbuds and I can't A/B test them to compare BT quality to a cable. I would say that the BT audio quality is equivalent to that produced when my Sony earbuds are connected to my smartphone. While it is decent, it can't compare to wired earbuds of even fairly middling quality. You lose highs and lows. For dialogue content, lectures and the like, no issue.SummarySeems to be a great entry-level transmitter for the average consumer. I'm glad I bought it, because it is reliable and easy to use, and has shown me that the freedom of using wireless earbuds is definitely worth the hit to quality - I can always use my full circumaural headphones if I want to watch a movie or listen critically. Would recommend.

Writing this after 2 days of use. Relatively easy to set up and works fairly well, at least for now. Several issues I noticed that may/not apply to everyone. For context, I'm using this in TX/Transmitter mode to avoid using cables between my TV and Soundbar.1) Latency - very minor in SBC mode, but noticeable. I'm unable to cycle to use aptX codecs with lower latency, presuming my soundbar doesn't support it. I double press the #1 button several times (slowly and quickly, but nothing changes). My soundbar has audio delay settings, so should be ok.2) Every time the soundbar reconnects to bluetooth, it sets the volume to maximum. There's no way to change this setting and it only started to happen with this bluetooth adapter. This is super annoying and makes the soundbar unusable without having a remote onhand to adjust the volume down before scaring everyone.3) When I try to connect my phone or other device to my soundbar using WiFi to play music, the soundbar auto-reconnects to the bluetooth receiver on TV and stops WiFi playback. This is super annoying and makes the soundbar only usable with TV.If the above doesn't sound like deal-breakers, it may work perfectly well for you. But for my use cases, this will not be acceptable.

This thing is great. I use it as a transmitter from analog source to digital headphones, and also as a receiver to listen analog headphones. It always connects easily and battery life is pretty good. Pro tip- turn off Bluetooth on your phone to keep it from auto connnecting to your phone. Very versital little tool for money. Range is great as well. Design is simple and the unit is nice and small. I Can listen throughout most of the house. Highly recommend.

Works great from my TV to headphones

Works flawlessly in doing what it should. It maintains a consistent connection and works great with my Air Pods Pro 2. I would buy this transmitter/receiver again.
