Blujax does exactly what I need it to and the battery does last a few days which after that it's a quick charge needed. Sound is decent as well.

I am very happy with this product. Does exactly what it is supposed to. Easy set up. Very small in size which I like. Doesn't connect phone calls - I wish it id. But does transmit GPS instruction from the phone.

I bought the product based on it's form factor despite it's price. It took my longer than I would have thought to connect to my phone. The center piece is a button but it's harder to push than I thought it should be. I think how hard I had to press caused the connectivity issues in the beginning. Once I had it connected, it worked great.

I purchased this product to convert my aux port to Bluetooth. The only other solutions were: (1) Plug my device directly into the aux port and deal with the cable. (2) Replace the factory head unit with an after market solution. While this solution does resolve the cable issue, I would like to see a few things improved before I can use it safely and seamlessly. First, have the unit power on when the ignition is turned on. Second, automatically start playback from the connected Bluetooth device upon boot up of the Bluetooth adapter. It may be technically challenging for a device in this price category to achieve this level of fluidity. In the meantime, I'm going to keep using my hard wired solution.

Works great. Now I can stream music from my smart phone to my car stereo. Easy to use. I use it just about every time I jump into my truck. Definitely glad I purchased it.

This is the second Bluetooth to Auxilary connection device I have purchased. The BluJax is much better than the other brand I tested.
The connection takes about 20 to 30 seconds to establish. That is kind of slow in my opinion. The connection was easier to establish than I expected.
The battery lasts a long time - which is good. But it needs to be charged. I would prefer that the adapter has some way of charging without a cable to the power source - or include a much bigger battery.
I would recommend this device to a friend simply because the options are limited - and this seems to be the best one available.

I purchased this item because my company vehicles stereo was not equiped with the bluetooth feature. I went to Best Buy looking for a device that would make my company vehicles stereo blue tooth compatible. I talked to an audio specialist who directed me to this product. I was a bit skeptical at first, but after purchasing and using this product, I will say that my expectations were blown away with the quality of sound, ease of use and the device being small and plugging into the AUX jack in the front of the car stereo. A++++ product! Highly recommend this product!

I am in outside sales and travel all of south Texas in a 2006 model 3/4/ ton diesel truck. ( no Bluetooth, just aux. jack) I have over 1100 songs on my android phone. This allows me to listen to my music via Bluetooth with excellent quality and volume.

Great product, my only complaint is that I noticed a slightly lower difference in volume, compared to having an auxiliary cord. You do have to charge it, but that's no bigger, battery life is 8 hours in one change.

As a battery-powered Bluetooth adapter, this fits nearly anywhere. It charges quickly and lasts for quite a long time. It will also let you pair multiple devices is useful for cars with multiple drivers. The biggest downside is that unlike car Howard adapters, this does not shut down when you turn the car off. It means you must remember to pause your music on the adapter each time you get out of the car.
Other than that small inconvenience, the sound quality was great and the overall usefulness was certainly a plus. This could also be used with older portable speakers that may not have a Bluetooth input.

Great purchase. This Aux to bluetooth adapter works great. It was the perfect solution to replace that stupid aux cord. We must have gone thru a half a dozen cords and eventually they would break and you would lose a channel and be listening to music from either the left or right side speakers.

I needed to turn my aux outlet in my truck into a convenient Bluetooth option. What a perfect way. This thing hides in the center console perfectly, good sound quality, good battery life, etc. Just what i needed.

I bought this to use with a fixed-install tablet (Nexus 7 2013) in my 2008 Acura TL.
Pros:
Small, initial pairing was easy, audio quality is good, charges via USB/car charger, signal is consistent, and it has the 3.5mm jack built in instead of at the end of a short and super-thin wire (like the competitors).
Cons:
Even though it remains "paired", it does not automatically connect to the paired device - you have to push the button once to reconnect every time. I wanted one that would automatically connect every time I started my car for a hands-free solution. The other issue is that the charging port is on the side instead of on the back with the 3.5mm jack so I can't mount it to my dash without having a cable hanging down from it.
Overall I'm ok with it, if I find one with automatic hands-free connecting I will get rid of this one, but it at least gets the job done in the meantime.

Average While It Worked

When I initially got this product it worked alright. I didn't like that you could only pair one device with it. I also had to get an adapter (female-to-female 3.5mm) in order to use this in my car; my mistake, though.
However after two weeks of use, the thing started playing the music VERY quietly. Tested in multiple cars and on other audio systems and it was indeed the bluetooth adapter. The adapter's charge was not then issue as I tried it in different charge states. Also the adapter does not have independent volume control; the volume is determined by your audio output device and not this adapter. In the end I found another product online that I have been happier with.

This product was really cool because it works with any streeo unit that has a auxiliary connection. Sound quality is really good however it dose have some connection issues when your trying to reconnect, and at least in my car when I am driving there is sometimes a low whine that plays behind the music however theses are nothing to worry about. This is a great product if your looking for a cheap way to bring your older car up to date by adding bluetooth music to your car however if you want to answer calls you will have to upgrade to the higher end one.

This is a nice Bluetooth add on for cars that have an AUX input plug, but not built in Blutooth. It has a rechargeable battery so it doesn't have to be plugged into a USB port all the time. Play time is 6-8 hours on a full charge. The only downside is that it takes 3 seconds holding the button to turn on or off. It would be nicer if there was a separate power button from the pause / play button. The sound is nice and it has good volume so the overall output is consistent between the adapter and other car audio inputs.
Nice job overall!

The size is nice and I keep it plugged in to stay charged. It works most of the time, but it may conflict with other Bluetooth items I have in my car sometimes. But the good thing is you can use it in any auxiliary jack and it makes this Bluetooth convenient. Works well when it does.
