Avantree Long Range Bluetooth Transmitter Receiver for TV & PC

I received my Avantree Oasis B Bluetooth 5.0 Transmitter: Gray, BTTC-500-W-EU yesterday 11/21/21 and it didn't take me long to hook it up as the instructions were very easy to understand. I already had an optical cable from the TV to my Sound Bar. So I disconnected the cable from the sound bar and connected it to optical input on the transmitter. Then used the optical cable that came with the transmitter and connected it from optical output to my sound bar. After a try or two, I was able to sync my Apple Air Pods to the transmitter and wow, the audio quality was just perfect. I also like having volume controls to adjust the volume to my Air Pods. My only complaint is the Bypass function. I wanted to be able to listen to the TV using my Air Pods and have sound coming from the sound bar at the same time. But when switching the transmitter to Bypass, audio comes out of the sound bar, but it cuts off the Bluetooth signal to my Air Pods. Since I was already using an IR transmitter & headphones which was connected by using RCA cables from the TV to 3.5mm mini plug to IR transmitter, I disconnected the mini plug from the back of the IR transmitter and connected it to the AUX port on the sound bar. Now I can listen to the TV using the Bluetooth transmitter and others can hear the audio thru the sound bar without having to use the Bypass feature! The other thing I like about this Bluetooth transmitter is when I connected the USB power cable to the USB port on the TV, when I turn off my TV, the Bluetooth transmitter turns off as well. and of course, when I turn on the TV, the Bluetooth transmitter turns on and automatically connects to my Air Pods! Since I just received the Bluetooth transmitter yesterday, I haven't really used it over a period of time, but so far I'm glad I finally decided to spend a little more money and purchase a better quality Bluetooth transmitter as the $9.99 devices never work as expected. I also ordered Bluetooth headphones which should arrive soon. Do yourself a favor, spend a few more dollars and get this Avantree Bluetooth transmitter... you will be glad you did!

I got this Avantree Wireless transmitter/receiver to use in place of the weak built-in wireless receiver in a shelf speaker system in my office that dropped the connection anytime I or my cats walked between it and my PC. This works great. I have it in my in-home office capturing PC WiFi from my living room 15-20 feet away and connected to the speakers via auxiliary wired input. It works consistently and the signal isn't affected by people or cats.

Overall, this seems to be a quality product. I paid $70 for this at the time of purchase. There are a number of cheaper options out there, but if you want something that is decent, this is one that I would recommend.Overall it does what it's supposed to do. There is a small amount of noise that this unit produces and can be audible through your speakers, but it is quiet enough that it can be ignored.There seems to be one caveat though, which is there is no optical audio output while the unit is in bypass mode.I reached out to their customer support about this to try and confirm that this is how it is designed or if I perhaps received a defective unit. The person helping me over chat was okay. When I asked her specifically if she could tell me if this was by design or a defect she said she would have to open a ticket with tier 2 tech support. After working with them, they did eventually give me an answer although I don't feel super confident about it.Also the user manual calls the button to change sources an in/out audio selector, but that is all and I am fairly certain that in bypass mode this only selects the input source, so a small knock to them on not including a very high level of detail in the manual.So in summary I would say that this is a "good enough" product with an under-documented user manual and decent customer support behind it. If you're not super picky, then you won't be disappointed.

I have two of these that I use to stream audio from TVs to bluetooth recevers. I have the power supply plugged into the USB ports on both TVs, so that when I turn the TV on, the Avantree comes to life also, and automatically streams the TV sound to my amps. I never think about them because I don't have to - they just work. For bluetooth needs, just can't beat Avantree.

Update 2: RETURNING this. It has become impossible for me to connect my headphones / earphones to the device. When turned on it shows that it is already connected to two devices. This happens every time turn it on.UPDATE 1: Whenever I connect 2 sets of earphones, the sound quality deteriorates tremendously. The sound is intermittent with random cuts and popping noises. Both my earphones have the QCC3040 chip and support the latest aptx codec. When connected to one of the headphones the transmitter also shows that aptx is being used (not aptx-ll). This is probably because it didn't have the latest aptx adaptive. I am using the optical cable to connect with my TV and a 5 V-900 mA power source. The sound quality is fine when only one headphone is connected.Using this device in transmitter mode with Bluetooth headphone. The headphones works great. I am not sure if it can take advantage of of the aptx adaptive codex though.I couldn't find input voltage specifications on the box, so I am using my TV's USB for power (5V 900 mAmp). Seems to work.
