## Description

desertcart.com: Ainostone 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 : Electronics

Review: Bluetooth Transmitter - it works - 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 desertcart - 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.
Review: Worked well, pleanty of connection options and cords included. - 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.

### ⭐⭐⭐⭐⭐ Bluetooth Transmitter - it works
*by A***S on December 28, 2024*

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.
