Title: Device emits disturbing sound artifact
Review: Device emits disturbing sound artifact when trying to use it with the car stereo auxiliary input. Instant return. Would not recommend.

Title: Perfect if you want to send bluetooth audio to an amplifier or speaker over 3.5mm input jack!
Review: So, the description does a pretty good job of calling out any confusions but let me break down this simple device…How it works, what it does:You power it by the USB port, it has a 3.5mm audio jack and includes a 3.5mm to 3.5mm audio cable that you plug into an “aux jack” (input) on something…That “aux jack input” could be the aux jack on your car stereo, that “aux jack input” could be RCA (Red/White Left/Right) inputs on a a Stereo/HT receiver/amp if you use a Stereo 3.5mm to Y-RCA adapter.This is how I’m using this tiny inexpensive adapter:I’m using this to add bluetooth to an old Stereo Amplifier, I plugged the USB end into a small 5w phone charger, the 3.5mm audio port is connected to a 3.5mm to Y RCA and connected to the Red/White RCA connectors on the back of the receiver.I then used the Alexa app on my phone to pair an Echo Dot to the bluetooth receiver (as the Echo Dot’s output device, which now goes into the stereo amplifier). The Amplifier is connected throughout the house to high-impedance speakers that provide ambient music throughout the house. I named the Echo Dot “Home Audio” and now if I tell ANY Echo device in the house to play “80’s Hits on Home Audio” (or whatever I want) it plays throughout the house! It also plays announcements on every echo device PLUS the “Home Audio” speakers!This is how you can make your ancient whole-home audio into a space-age voice-controlled juggernaut for less than $15!!!

Title: Feels cheap, works great
Review: I was tired of my “audio system” for my projector being in weird positions due to needing an aux cord plugged into the projector, so I opted for this adapter.Upon taking it out of the box I noticed a faint noise so I shook the device a bit, surprised to find out that the internal components don’t seem very well secured in the plastic housing. This is a cause for concern because it could be a point of failure as the hardware moves more and more over time.It does come with a 3.5mm TRS aux cable, in the event you don’t have a few lying around. It’s a nice braided cable, too.Setup is simple just plug the usb into a power source, plug the aux into the usb and whatever you want to make bluetooth. Note that for some devices (TVs for example) you may need to adjust the audio delay for bluetooth, as my setup did not automatically accommodate for the delay like most would.

Title: Junk
Review: The audio quality is terrible, the connection time is terrible, the lag is terrible. Music is distorted through this device via Bluetooth, and takes 10+ seconds for songs to pause or change tracks. Waste of money.
