I wanted to love this to use in my old car which I love, but it was a few years before Bluetooth everything like we have now. The problem here is the static. I think it may be in the cord as if I move it at all the interference seems worse. However, it does not get better manipulating the cords in any direction. It connected quickly and everything else works as stated.For this reason, I cant recommend this product!I received this product for review. I was not paid for my opinion, I have not been contacted by the seller, and my opinion is my own honest opinion for better or worse. The only difference between my normal reviews and my Vine reviews, are I try to go more in depth out of courtesy for others and in respect of the program itself. I also still have to pay taxes, actually use the product, and spend time writing this. I borrowed this initial format from another vine program reviewer, but did not get his name so whomever you are, thank you!!! My impression overall of the vine program as since the sellers know we are free to leave our honest opinion, they believe in their products before putting them into the program!! I say this because I have appreciated the quality of products I have received and the few that I had problems with, I think could be better with minor corrections.-------------------------------------------------------------------------------Overall Rating★ - Product is in dire need of improvements before it is worth purchasing. I would probably not consider purchasing again.★★ - Product does not meet expectations, needs improvement, and/or is not worth purchasing at the price-point. I might consider purchasing again with improvements.★★★ - Product is adequate, as expected, and is average for it's quality, price, and features. I would consider purchasing again.★★★★ - Product is above average and meets specific needs. I would purchase again.★★★★★ - A fantastic, well-made product, that meets specific needs/wants, is expected to last, and I would absolutely purchase again..

I needed this to connect my new phone, which does not have a 3.5 mm audio jack, to my car stereo (car Bluetooth is broken). I am using this entirely for music/podcasts from my phone while driving and it is perfect for that. I had this connected and working in about 5 minutes and it worked perfectly. You can pause playback via the device itself, which is also nice. I have not used this for hands free use of my phone for calls since I rarely actually talk on the phone and I don't spend that much time in the car. I highly recommend this to anyone who cannot connect to their car Bluetooth for some reason and has a newer phone without the audio jack. I'm really that such a simple solution was out there.

So I have a fairly old car (2013), but I like my fairly old car. The ONE thing I do not like about my fairly old car, is that it has a fairly old sound system. It's a really good fairly old sound system, but it lacks modern things: like Bluetooth audio. It has Bluetooth for phone built in, but no audio. So I ordered this device. Here's the good and the bad:The Good:1) It's super simple to use. Plug it into the included USB charger, plug it into the aux port, connect your phone to a new bluetooth device and you are all set.2) The design. The build quality has a durable feel to it, and I really like the design. Small footprint that will attach easily and almost fit in with the rest of the dash controls, assuming I keep it and attach it. That leads me into the bad:The BAD:Sound quality. There is a lot of noise from the connection. If you turn the volume way down on the dial from the device, it reduces it to a useable level...but the quality just is not great. It's fine, but not great. I'm actually assuming this is, at least in part, due to the aux cable/cable connection. I have some higher quality aux cables laying around somewhere, if I find them I'll swap them out on the device and update my review if it makes a difference.I had to go on a 100 mile round trip drive this morning after the device arrived, used it the entire time. Never had a problem with the connection dropping, device did not overheat at all. The quality was entirely fine for audiobook streaming. I did not test the phone function at all, it's just not necessary to use in my application.

I got this to use with a small amp that powers a couple speakers by my hot tub. I was happy with how easy it was to set up and start using. Unlike some of the other reviewers, I didn't have any issue with static and the sound quality overall was pretty good. The only issue I had is that the volume level is pretty low. I tried it with a soundbar in the house and compared the sound from this device with a direct connection to the soundbar with bluetooth. The volume level from this device was about half the level of the direct connection. I'm not sure if that's just an AUX line issue or what, but it isn't an issue to just raise the volume. It will still get loud enough for how I listen to music.
