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

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.

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

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 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.

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.

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

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

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.

Husband cant hear on audio tours. This will enable the audio guide to transmit directly to hearing aids via Bluetooth
