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

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.

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

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.

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

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.

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

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.

Returned two because the LED never came on.

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.
