Connects easily everytime to my device, transmits great sound through the aux port.

What I liked about this device was how loud it was in my car, the sound was crisp and clear. What I didn't like about it in my car was how I had to connect it to my phone every time I got back into it; I also found it annoying trying to connect my phone every time. What made this device even better was connecting it to my guitar amplifier, and playing music along side it. When it's all said and done it's worth the price, you can't beat it.

Good connection quality and battery life. I'm just kind of a dummy so I wish I would have spent the extra $5 and got one that was easier to work. With only one button to work so many settings its kind of a pain sometimes getting it to connect. A smarter man might have am easier time with it but idk. Overall works well

I was a little skeptical going into this purchase due to the price so my expectations were low!
Upon arrival, which arrived a couple days later (USPS, they're not the greatest), this thing is pretty small and nice looking device!
It came with the device itself, a short (stubby) 3.5mm to 3.5mm jack, a short 3.5mm to 3.5mm cable, and a USB to type C cable to charge device. It was easy to pair to my old Note9 phone (I used short stubby adapter to connect to my radio). The lights on it is intuitive to let you know the status of device.
The device has several controls on board for volume control, voice answering phone calls etc (haven't tested that yet). I left my volume set to max on device along with my phone set to max volume and just controlled master volume through the radio. I must say, I was using a good quality 3.5mm to 3.5mm cable before that was becoming annoying, but this device for some reason has improved the sound quality of the music! I noticed that I didn't have to increase the master radio volume as much as before and the sound quality was much crisper, bass was puncher (even with one of my speaker being slightly blown)! This device must be processing the sound better or something before entering the radio, I don't know! Yes you have to connect to it each time you turn it on (not automatic) but it's a miner gripe for me and will give it a pass due to the value and impressive sound I'm getting from this thing not to mention no more long cable hanging around again! It was said by some that when in use and plugged in for charging in cigarette lighter (which is great that you can do) can make/ have that awful buzzing sound (interference) coming from it (my older cable did it/ unusable when I plugged and charged my phone), the sound was extremely minimal was there but for me it was minimal! Now I haven't tried charging my phone when operating this device to see if there's any interference yet! I still have to test other features but so far I would definitely buy another one if need be so far, great value at $12.50 (less than 1.5 dozen of extra large eggs these days🤣)! If anything occurs or something I will add to post or adjust my thoughts in the future!

It is super easy to use and is great if you just want it to transmit. However, the application I was attempting to use it in required there to be no, or at least negligible delay. Unfortunately, there is nearly a 1 second delay from source to headphones, so be aware of that
