Bluetooth Transmitter Receiver, Low Latency 4-in-1 Bluetooth 5.0 Audio AUX Adapter with Display Screen, Wireless Aux Bluetooth Adapter for Car, PC, TV, Speaker, Headphones, Home Stereo System

Im not rating the volume control or the battery life as I use the volume control on the Ipod and I havent had the device long enough to see how long the battery lasts. The range appears to be upward of 100. The device was promptly delivered.

Crazy high latency, very annoying when trying to watch TV and the audio is a second behind.

The unit seems to work as a transmitter which is what I needed it for. Unfortunately the display is impossible to read its so dim. I had Amazon replace and the second was just as bad. UPDATE: After a day it no longer connects to my speaker. Again the display cannot be seen... so I give up with this.

The led/lcd screen is extremely dim. Any ambient light at all and screen is washed out. Device does work though. Hoping replacement is better - would be nice to see what is going on.

I get about a full second lag in my sound delivery. I am using it to privately listen to my guitar as I play it and each note comes in a second after struck. Makes it impossible to play. Using Sennheiser bluetooth headphones that play without lag on my other devices. My wired headphones have no such lag with everything else the same. I expected some lag but a full second is a bit too much.

Super simple connectivity. Connected to my earbuds right away and began operation. Built in screen makes connection easy. Im not using this on high fidelity earbuds so quality is something unknown but for the price and my needs, this was the purchase I should have made first.

I was looking for something to add Bluetooth to my tv so I can use my beats headphones to watch. The screen is decent shows me everything I need to see. Battery and when the device is connected / searching for Bluetooth device. Battery life is great it last as long as my headphones and charges fast. I’ve watched about 8 hours and the device still had charge. In terms of connection it’s also good as the is no time lapse between the voice and what reaches the headphones. Overall great product for the price.

Almost a full second latency when using with a television. I imagine that if you aren’t using with a television it might be fine, but advertising as low latency is not how this works at a practical level. I’m going to have to return.

Positive: easy pairing Negative: HORRIBLE sound quality, kills all bass when transmitting signal.

I like the functionality of the device but it sounds flat and lack audio depth.
