Bluetooth 5.0 Transmitter Receiver, 2 in 1 Wireless Bluetooth Audio Adapter with aptX HD Sound, 2021 New Version 3.5mm AUX RCA Adapter for TV/PC/Car/Home Stereo Audio System

I bought 2 of these, and tried them both with no success. I have a B.S. Degree in Electronics, and I'm an Electronics Technician with decades of experience. I know what I'm doing and how to make things work. I simply wanted to transmit from my TV to my bluetooth headset - nothing I tried worked. The manual in the box was not clear at all, and no technical support was available. The support I requested came back just as unclear as the manual in the box. Very disappointed - look for a brand that backs up their product, provides clear instructions, and provides email and/or phone support.

Lots to like…. It got the job done. Toslink DAC works. BT does not reconnect and hear my reason…. I have another one from another brand and it took over the BT and connect to my phone whenever I turned it on. For some it may be a feature but for me it’s utterly annoying. This one does not connect BT Rx automatically so I can control which device I connect to via my phone. Sometimes less is more. 3.5 mm or RCA out both work well. Only negative was the 3.5 mm from DVD/CD does not sound too good, works though and Toslink from same DVD/CD works beautiful. zone 2 RCA out from another amp was as good as it can be. So it may be just a case of impedance mismatches. I use this to go to the newly acquired hobby vintage amp to the aux port and works well. Only things I would like to see in addition is the DAC specs….16bits/24bits res? Not incline to open it up and check the chip out. So solid 4 stars but I would give 4.5 if I can select that. Five if there are info on the internal chipsetNote: a prior reviewer gave a 1 star froma self declared well seasoned EE, not sure what happened to his setup. Sure does not sounded like a fair assessment to me since the setup is elementary and a breeze. From one EE to another.

Bought as transmitter for webcast lavalier wireless mic solution. RX mode works great. Battery life is great. Audio jack good for wired mic or wired headset. TX mode has issues with Windows 10 which has CODEC issues with BT APTX profile (maybe APTX-HD). Not chipset or BT 5.0 issue. Maybe MS CODEC licensing issue. If fixed this would make great webcaster wireless mic solution. Without fix will need to use proprietary wireless (consumes PC audio jack) or AV industry wireless mic solution (X times total cost of ownership & still consumes PC audio jack). Tried other BT wireless headsets WITH MICS and newer USB BT 5.0 adapter and have same Windows 10 issue.

Easy to pair via Bluetooth. Good sound. We use it to feed Alexa music streaming to our home theater stereo for better sound quality. Volume control is via the input device, as this has no control of its own.

This almost perfect! My only complaint is that even when plugged in, it turns itself off when not used for an hour, and you have to manually turn it on, with 3 sec hold to start BT search again... kind of annoying! And the turn-off time is not adjustable..

I had so much trouble with this device that I’m sure no one could get it to work. I installed it according to the very poorly written directions and the only time it would connect to my phone was only on the initial mode. Once I changed the mode to any other mode it would disconnect from my iPhone.I really wished that it worked and will try something else for making my Smart TV Bluetooth connectivity. Very sad product!

Easy to charge and hook up to our TV. However, when watching a movie the sound is not in sync with anyone's lips when they're talking, making it distracting to watch and see the lips move moments latter. It was installed about ten feet from our speakers. Yes, I'll be returning it.

This Bluetooth transmitter works beautifully to send output from my old Sony Walkman MP3 player to my ear buds. I was looking for a Bluetooth MP3 player when I found this, and it did just what I wanted.
