Chasehill Bluetooth 4.2 Transmitter and Receiver, 2-in-1 Wireless 3.5mm Audio Adapter, aptX Low Latency for TV, PC, Car, Home Sound System (Black) (Transmitter&Receiver)

Did not work at all.First one arrived with 2 aux cables ... no usb cable ... so i couldn't charge it. I found a usb cable of mine that fit and it did power up, red and blue light. The smartphone picked up the signal and showed connected but it did not transfer audio. Just did not work. Cheaply made compared to other similar priced bluetooth. I was really hoping these would work since all bluetooth devices are sky rocketing 3-4 times their worth. UGH!

tried to pair an analog record player with an Amazon Echo. I have a 1st gen and a 2nd gen echo. strangely it transmits mostly okay to the 1st gen, but for some reason the 2nd gen just has a terrible time with it and it stutters and pops. any other bluetooth device streaming to either device is fine. for <$10 I'll probably keep it. since it works with the 1st gen but not the 2nd gen I don't know whether it's this device or something wrong with the echo's bluetooth.

"TX MODE: Pair with your Bluetooth headphones/Speakers. I have found that TX MODE only works with Bluetooth headphones/Speakers. Will Not transmit to... only receive from Paired Bluetooth enabled Cell Phone or PC. Won't Do TX and RX at the same time. Works as advertised.

Tried to pair with several devices, that was a total joke. I gusee it would be good a a paper weight, not much else.

Used in watching tv and movies. Too much delay on the voice end to use for that. Ok with just music.

For the price I should have expected the sound quality to not be so great. Once I got it connected to my TV the sound quality was unbearable. The audio was delayed, constantly skipping, and making popping noises all at once. This may work okay with other devices than a TV but with failure at such a simple task I couldn't care to find out. It also looked as if I was given a returned one as the box was opened and packaging was upside down. Product was covered in finger prints too.

Really like casting music with Bluetooth over to my home receiver and even to my boombox.

Kind of weird accent when notifying about the connection..., other than that very efficient
