iDIGMALL Bluetooth 5.0 Transmitter Receiver for TV, 2 in 1 Wireless Audio Adapter for PS4 Xbox PC CD DVD Radio Projector Car Home Stereo Headphones with 3.5mm/ RCA Aux Jack Dual Stream & Low Latency…

For the longest time I've got by with a set of Audio Unlimited 900MHz wireless speakers, but finally the wireless environment in our home got too much for them and they suffered from uncorrectable interference that spoiled the enjoyment of TV via our projector. So we decided to try a bluetooth audio transmitter instead, swapping out the Audio Unlimited tin cans for quite a nice sounding JBL3 that my wife uses. Unfortunately I then discovered about the issue of audio lag/lack of synch with the video which had never been a problem with the Audio Unlimited hardware. Turned out the JBL3 didn't have the latest low-latency BT audio, and audio was noticably delayed by maybe a third to a half of a second - certainly enough to make it unusable. (Someone needs to invent an HDMI video delay line to compensate!) Anyway, it appeared the solution was to double-down and buy a second BT device, since these ones support both transmitting and receiving, and use low-latency mode when talking to each other. Well, it works - sort of - my guess is the latency is down to one or two video frames - enough for me to notice it but not for everyone to notice. I guess I can live with it, though at some point I think I'll have to run a wire under the floorboards or above the ceiling and eliminate the delay properly because I *am* continually aware of it.Apart from the real-time issues, these do seem like quite nice devices, with a trivial pairing procedure (just hold down the button - didn't even need to scan the manual) and no 4 digit numbers to enter. So far I've been running off the pre-charged internal battery but soon I'll have to attach a micro USB to keep them charged. It does look like they can charge and play at the same time so shouldn't be an issue at all (apart from a few dollars extra for the two PSUs, but who doesn't have a bunch of those lying around nowadays...)

I don't have much experience with blue tooth devices so I was hoping that this would work for what I wanted. I wanted to listen to my 5 CD player at pool side while the player was closed up in the pool house.I read the instructions and it seemed pretty simple. I first charged the transmitter via the USB port with the supplied cable. The red LED when out after about 45 minutes indicating full charge. I plugged the transmitter into the stereo headphone jack of the CD player with the supplied cable and turned on the CD player, transmitter and the blue tooth speakers I bought to use with this set up. Without doing anything else, after about 3 to 5 seconds the speakers played the "I'm synced" tone and that was all there was to it.The sound quality was excellent. As good as the CD player speakers. I can't vouch for battery life. I used it about 2 hours and was done for the day and put it back on the charger. I also only used it about 20 feet from the speakers so I didn't test the range. I may update this review after the next use.The transmitter was used the the following speakers, and super easy. True plug and play:https://smile.amazon.com/gp/product/B07RMH3W8Y/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1UPDATE:I checked the range today and carried the speakers away from the transmitter until the audio started breaking up. I didn't measure it with a tape measure but it was at least 33 feet, probably a little more. So I would say the stated specifications are accurate. Still very satisfied with purchase.

I ordered this Bluetooth transmitter to be able to play my analog record player thru my wireless surround sound system. I connected the transmitter to my phono preamp and turned it on but it wouldn’t connect to the surround system even though I was only about 10 feet from the soundbar. I unplugged the transmitter from my preamp and walked it to within a few feet of the soundbar and it connected almost immediately. I then plugged it back into my preamp and bingo, my record player was playing thru my wireless surround system. Although the transmitter wouldn’t connect unless it was a few feet away, it had no issues staying connected when I walked it back across the room and plugged it back into the preamp. So, with a little work, this was a good solution for me.

I like the size of this one and it is very easy to use and works great. Instructions are also easy to follow.Works well with my DVD player and radio. (neither has bluetooth) but with the transmitter, I walk around listening to the radio or watching a dvd on the player along with my bluetooth headphones! What a simple solution!

So far so good. Purchased product to connect to a MP3 player I purchased for walking audio tours for hubby and I to listen to one device at the same time....will update after trip. I am also going to try using it for our TV...at times I want to listen to something while he is studying, this way I can without disturbing him.

This thing is great because it enables my Bluetooth earpiece for running but it plus the earbud, plus my iPod nano have to be at full power for the complete system to work at all. I'm used to just being able to grab iPod and earbuds and GO for days without charging, wheras with this I've only been able to use it a handful of times because it takes forever to charge to full power, and if I forget to charge 1 of the 3 components--or one wasn't plugged in completely----forget it! Still have to carry this during run plus iPod and have earbud so it's just annoying carrying one ore piece, especially since this doesn't have a clip.

It worked well but there was no easy way to switch from the Bluetooth to my TV speakers without physically walking up to the tv and unplugging it.

when you unplug it the tv volume is very high. if you don't turn it off the battery dies quickly. It does the job
