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

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

Another happy camper. Took less than 5 minutes to figure out. Came in rx (Receiver Mode) instead of Tx Transmission Mode. Read manual and switched to TX and hooked to my Sony Xm4s Easily and Flawlessly. If I have one criticism it has a list of earbuds that its hooked to and no way to remove earbuds from the list. Not worth docking a star.

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.

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.

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

The battery in the TR arrived totally dead; Normally this is not good on a battery. Finally ... it started charging and came alive. I have used it several times and have not drained the batteries yet. I intend to do a battery life test to see if the total drain harmed them; if those results are bad Ill update this review. Have used it through closed doors and I still get good distance. At distance, people crossing the path between the TR and the audio item causes drop outs, but they are minor. The sound quality when using it with very high quality BT speakers was no different than hard wired. Recommend.

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 have now purchased three of this type Bluetooth transmitter. This on happens to be the least expensive of the three and absolutely works the best. It connects easily to either my Bluetooth speakers or my headphones.

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

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.
