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

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.

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.

Looks like it’s great based on the star rating, but 95% of those positive reviews seem to be for a book in Portuguese. Full second delay - nearly unusable.

After 3 days of use, fully charged, the display screen went so dim that it is barely readable. Returning this item.

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.

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.

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

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.

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.

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