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 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.

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

I have purchased three other bluetooth transmitter/receiver devices of different brands, most more expensive than this one, and they all had a very nasty flaw when transmitting. Once the volume of the input sound source drops below a threshold, usually not very quiet, the sound in my earbuds would fade in and out and sometimes shift left or right due to fading out the quietest side. This is the first product of its kind that I have purchased that does not suffer from this very noticeable and annoying sound issue. This alone is enough to make this one a keeper. I cant yet speak to battery life, since I havent had it more than a few days and havent played with it much, but it seems very good so far. I do notice that the tx mode seems to start muted, as I need to press the center button to get sound to my buds, but I can certainly live with this. Test phone calls also seem a bit quiet, but this could be due to echo cancellation or something similar, as my test call was made to an echo test number, and I really wasnt expecting much from this feature, although it is nice to see it available, and this is the first product I tried that could actually take phone calls. I will need to play with this feature a bit more, but for basic use while on the phone, it seems good enough. Over all, I highly recommend this product, especially for the price, and I am considering purchasing more of these just in case they are discontinued in the future. I dont want to be without one in case of a battery failure or other breakage that can occur over time.

Returned two because the LED never came on.

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 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.

Thank you for fast shipping, product it is working with my Bluetooth so easy to hooked up

Works great, now I can watch tv with Bluetooth earbuds and not wake up the kids.

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.
