Bluetooth Transmitter Receiver 3-in-1 Bluetooth 5.3 Audio Adapter for 2 Headphones with Bypass Volume Control ON/Off Switch LCD Display 3.5mm Aux/Optical/RCA for Home Stereo TV Speaker PC

Easy to install, works exactly the way I wanted. The tiny speakers in my bedroom TV were difficult for me to hear and when I turned up the volume to near maximum There was often distortion. Since I primarily watch You Tube this made the information hard to understand and annoying to listen to. This TV lacked Bluetooth and I didn't want to hardwire any extra speakers across the room. I installed this unit as a BT transmitter, and paired it to a wireless speaker above my headboard. (see separate review of speaker I used.) I had to turn off built in TV speakers in TV's native setup as there was the annoying distortion and slight latency from the wireless speaker. I used the usb output on the TV to power this unit and was pleasantly surprised to see it turned off the power to this unit when the TV was turned off. The transmitter 4retained the speaker pairing when the TV was turned back on.

Quick - it works in transmitter mode, comes with useful cables that are long enough, and the display screen is very helpful. Doesn't come with a charging block (but what does nowadays). I haven't tried in RX mode so can't speak to that.Detailed - I tried 3 other options before this transmitter and they weren't great. Some issues I had with the other options that I found on amazon - latency or audio lag, blind device connection, lacking connection cables, requiring charging/ not powered, not reconnecting or remembering the same device when it's powered back on, really bright distracting indicator lights, and disconnecting at short distances. This one works and doesn't have any of those issues.The screen is key and makes it so much easier to pair with devices and check volume and status. If you press the play/pause button you can mute your device, but using the controls on your headset work fine too. It came with various connecting cables. I used the optical as I wanted to use bluetooth headphones to connect and listen to tv audio. I've not tried to use it in receiver mode. I have experienced zero audio lag. It remembers the devices that I've connected it to after it's been powered off. Has distinct separate buttons that make it more usable. I've had clear connection about 25 feet away (unobstructed).Only negative for me is that it does not auto-shut off when not in use and the volume light is always on.

Used the digital audio from tv to setup bluetooth speaker across the room. Great quality and easy setup

Tried for hours. Connected the iPhone to the device, and then paired the AirPods to the phone but there was no sound. And of course, the return window closed by the time we tried to use it. Using the troubleshooting guide provided on the Amazon app is for a different device for a car including plugging into a cigarette lighter, not even the same device I purchased. JUNK

1: Just me, I connected optical cable to my Roku tv, sound is fantastic, connected Anker speaker first, really good sound2: Then connected Between Pro ear buds, sound blew me away, even people with a heavy accent was clear and understandable.3: I can walk any place in my 4 bedroom home and will not break connection, up or down stairs.4: Used TX connect, do not have need for RX, but should work well.5: No battery, can us usb connect on tv, connection is easy directions are fairly readable, if using optical cable, remove rubber protection pieces.6:Yes Yes you can have the tv speaker on also, maybe not all TV's check ur tv settings , if using ear buds or speakers without volume control u can use volume control on wireless adapter.7: I have used a lot of wireless adapters, none were as easy as this BT17 to set up, good instructions and very good distance from wireless adapter I just bought another one!8: UPDATE, if you use optical u cannot use remote to control the volume on Roku tv, connected to sound bar should be able to use soundbar remote.9: To use tv remote to control speaker use the output for Aux (headset) on tv and transmitter, go to settings for tv, Audio - audio output, set ✓Auto, now on Roku you can mute and control volume, tv will only allow head phones volume to be minimal, now adjust wireless speaker volume button to go higher. This may or may not work on other TV's with optical cable.

This thing works great for me, I use it to play sound from tv to earbuds. I have since got a new tv that will do that too but the transmitter gives me longer range to walk around the house and listen to music or news. for the price you can't beat it. If you want to play sound through a soundbar at the same time you will need to get a splitter is all.

Unit will NOT pass audio through the fiber optic out port. The fiber out port is VERY dim. Very, very dim. So my sound bar no longer works, and I'm FORCED to use my headphones at all times. If it didn't have a bypass function it lies about, it'd be a good product. Works great with my plug in headphones and I'll try it with my BT units later. I do NOT recommend this unit unless you just want it for headphones... and don't need your PCM/optical/toslink to work for anything else. And I have it plugged into a 45W power supply. So no issue with the power not being sufficient. If you just need a cheap liar then it's great... I have an ex you might like too.

Seems to work but so far have not been able to fully test as I ordered a bad splitter cable. Would be better with a built-in battery. I did get it to work with 2 sources at the same time: optical and 3.5 mm cable but there was a considerable amount of lag with dialogue coming through my Bose earbuds where it created a horrible echoing effect which is very unpleasant. I will do some more research and testing. It may be that this is just an inherant feature of bluetooth.
