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

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.

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

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

Dim display is useless during the day. If it is pitch black at night, the dim display can be read - but during the day forget it.

I purchased this product because it advertised low latency It was anything but, very disappointed.

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.

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.

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 screen is dim, but only so the battery can last longer. What do you want a Bluetooth transmitter with a battery that only lasts 30 minutes a charge? The battery is long-lasting and comes our of the box with 3 bars of battery. It connects very fast. Listen to the 5 star Japanese book reviews because thats the star rating this item should have. Dont listen to the negative ratings, their just people who dont have the patience to learn something new. It also works with xbox one, since it doesnt mention that.
