Very effective bluetooth reciever in a super small form factor
I bought this to use with the aux port in my vehicle in order to stream music and audio books from my phone. It has been surprisingly effective for my needs and I will be permanently mounting it on my dash. The battery life has been very good. I'm not sure how long it lasts because I haven't taken any long trips since it arrived but I have not run the battery down yet. I was skeptical initially because I have had terrible experiences with many other bluetooth devices but this one seems to be a great choice so far. I do recommended a shielded charging cable and possibly a shielded aux cable if you plan to charge it while listening because there is a noticeable hum with the cables it comes with. The price point is very good and even if you replace the cables you would still be at a great value. The sound quality is equal to or better than playing directly through the aux cable. Also wanted to mention it is very simple to use and pairs quickly without hassle.

Bought it Again!
I just bought this for the 2nd time after having used the same model continuously for almost 8+ years! The original one held up well, but the battery understandably deteriorated over time. But it has been so good, I didn’t think twice about ordering it again! It’s easy to set up, mount and operate. Very straightforward, very reliable and very sturdy. Highly recommended!

Easy to set up and use.
I bought this so I could use Google maps in my Audi without having to replace the stock head unit. The Bluetooth Aux Adapter worked fantastic. Great sound quality, easy to set up, and best of all the phone connects to it automatically every time I get into the car. Having used the FM transmitter styles in the past, and dealing with the static and "fuzz" noise, I was pleasantly surprised that there is no noise interference while using this. I would highly recommend this Bluetooth Aux Adapter as a way to add hands free calling and Bluetooth music to a factory system, providing you have an AUX port. Update: The only complaint I have is, the unit has a ring around the center that changes from a solid red, to a flash of blue every 2 seconds, while Bluetooth is connected, which is very distracting and annoying while driving at night time. I wish there was a way to turn that off. I am going to take a Sharpie to it tomorrow to see if that will at least reduce the brightness of the flash. Deducting 1 star for this as issue.

Impressive!
I’ve tried a couple of other Bluetooth converters and this is by far the best! The sound quality is better than a cable connection. My only critic is the blinking “on” light. Can be a little distracting but easy to get use to. I highly recommend this product.

It's easy to set up and it works!
I don't write a lot of reviews but I just have too on this nifty gadget! I've got a 2011 plain Jane Civic LX that I've been trying to hook up the car radio thru a 3.5mm auxiliary port so I could somehow connect my phone (I've got Spotify with nearly 2000 song) to it and hear my tunes! If your in the same boat look no farther my friend! It was easy to pair to my phone and once plugged in off we went! That means I also have Sirius XM,Pandora,and I- Heart if I want as well. In my case the charger cord takes the same as my key fob so we're all set! I highly recommend!

Product works exactly as advertised
I purchased this Bluetooth audio streaming device for my work truck after upgrading my smartphone since the new phones do not have aux ports and the music stations in my area are not pleasing to listen to. When I recieved this product I was very surprised to see that it came with multiple adapters. It charged very quickly to a full charge and I have used it for a week and haven't needed to charge it again. Tha battery life is impressive and it pairs with my phone very easily. This is a great product and just plain works. Easy to use, clear sound with no interruptions, great battery life, and works for media and phone calls. Thank you for this great product!

Buy this for someone you hate
I never thought a simple Bluetooth aux product could be more annoying than helpful, but this tiny piece of electronics far exceeds anything I've ever anticipated - and not in a good way. The sound quality is okay, and it does take very little space. However, the battery doesn't seem to last very well - at least, it becomes an annoying beacon to your own recklessness to ever allow a battery to drop below 50%, in which it proceeds to interrupt any music playing to remind you of this every few seconds even if you have it plugged in and it's below that percentage. Want to enjoy music? Too bad, guess you'll have to wait for a full charge and prioritize this tiny piece of plastic over your own life and demands. Also, it flashes a vivid, pulsating, non stop blue light whenever it's on. It's brighter than a cop's hood light and you might risk impersonating one if it somehow ever got on top of your car. It could probably be seen from space, and it's feisty and won't ever stay flipped in a position where it's both useable and not blinding everyone in the car. While this next critique is a minor inconvenience, not having buttons to change the song easily and has some weird secret handshake to answer a phone call became more burdensome for the risk of a sleek look that does even matter because everyone immediately shuns this annoying thing. If you buy this make sure it's only for a person you detest but for some reason have to keep in your life to the point gifts are required.

A large circular flashing blue light that never stops
I bought this for my old truck with an aux input. It works fine and sounds the same as a cable input. No complaints on sound quality or operation. However, for some insane reason, someone thought it would be a good idea to have the thing flash a large circular blue light the entire time it’s on. Not just a simple on/off light but an incredibly annoying flashing light that never stops. So if your jam is to have a mini strobe light going off in your face while driving this might be the Bluetooth dongle you’re looking for. Of course there’s always duct tape. That solves every dumb problem.

Edit: Company was A++. They sent me a replacement super fast. So far the replacement is trucking along just fine. The one I originally bought that went completely dead must’ve been a one-off manufacturing defect. Hey, it happens to the best of companies. Battery life is much better this time around on my replacement device, sound quality is good-superb just like before. No pops or static or anything. Very clean. Range is excellent as well. Sometimes I’ll forget to disconnect my phone when I stop somewhere and get out with it to go into a store to pay for gas or something and I’ll come back into the car and the podcast/music will still be playing. As in it never lost the signal at an estimated 50-80ft plus range. Just my everyday use review. Not sure on its max range. It’s a good product for its price. And if there’s an issue customer service is prompt and dedicated. —————————————————————— Sound quality was good. Battery life was meh. It would last I estimated 3-4 hours max before it needed to recharge. But I only had it just over a week of light use and it just wouldn’t turn on again one time. It died and went kaput. Spend your money on something else that’ll last you more than a week or two.

Pretty good device for the price. Easy to install, and came with double sided adhesive to install on the dash. You have the choice of plugging in the aux connection directly into the device or use a cable to be able to move put the device anywhere. The aux cable as well as the charging cable are nice and long. I strapped them up with a zip-tie to avoid dangling cable. My cellphone connects automatically to it when holding the button for a few seconds. Press once to mute or twice to call the last recent number. Sound quality is good during calls. Only downside is see at the moment. Phone call volume is all the way up, but I have to crank up the radio to hear. Once the call is done and the music comes back up, it is crazy loud and I quickly have to turn it back down.

Works great. Quick connectability. Easy to use. Very happy with battery life. Would buy again.

Easy to use. The first time I used it it took a few minutes to find my device but after it go connect once it connects instantly every time. The one button is easy to get pushed accidently when in your pocket so I try to keep it in loose fitting sweater pockets. The sound quality depends on your headphones. Doesn't take very long to charge.

I like this because I can use it for my car stereo and my old headphobes that I love. I used it for a 5 hr car trip and it lasted no problem and there was still charge left when I used it the next day. It connects easily to all my devices and sounds really good.
