1Mii Bluetooth 5.2 Transmitter & Receiver for TV - Wireless Audio Adapter with Dual Link AptX Adaptive/Low Latency/HD Sound | Compatible with Home Theater, Headphones, Airplane, Boat & Gym Workouts | Perfect for Movie Nights, Travel & Fitness

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 from 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 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.I've bought over a half dozen audio jack - to - bluetooth converters. I travel a great deal and wanted a wireless connection to onboard entertainment systems on planes. This one actually works. Sound quality is primarily a result of how worn out the audio jack is on the plane. If the port isn't worn out, it's a very simple process of plugging it, switching to transmit, and hitting the button to connect to your ear buds or headphones. And I thought it reasonably priced.Small, light, works as above described are pros.The short audio cable is already finicky… I am ordering a 1 ft cable with right angle lead to replace. Wish the transmit was a bit stronger to stream smoothly up to 50 to 60 ft range.The Bluetooth on my computer failed. The 1Mii Bluetooth 5.2 Transmitter Receiver works great as a standby until the issue is resolved, then I will find other uses for itOnly complaint is after a while when there is no sound, it shuts down. It's easy to restart.Works as described uses the new codec clear clean Bluetooth in HD.I bought this to use on a plane with my wireless Bluetooth headphone/earbuds and it worked like a charm as well as you can charge it while using it. Great for a plane!!Tried it for the first time this past week and was surprised at how easy it was to connect to the headphone jack on the plane to my Apple AirPods. There was no delay in the sound when watching movies. The sound was great.Was worried that there would be a problem connecting projector audio to wireless speakers because there is no menu to select audio devices but when I set the device to transmit and set the Bluetooth speakers to broadcast, they connected automatically! Battery power lasted well through out the movie. Only thing is over a period of time (2 hours) you have to rest the connection (audio volume decreases); don't know if the issue was in my wireless speakers or the Bluetooth transmitter.
