Efficiently charges and plays audio; suits my needs perfect

Works great - even with a bumper around the phone.  Exactly what I was looking for.  Using this dock for music into an old home theatre system now in the garage.  The base is magnetized which holds securely in place inside a gladiator garage cabinet.  The built in 3.5mm audio is perfect.
 Highly recommend.

Works very well to provide an isolated power source for a music player or phone plugged into the aux port on a car stereo. Whenever I tried to both charge my phone and play music on the phone via a wire plugged into the stereo's aux port at the same time I had a terrible whine proportional in pitch to RPMs without this unit... but with this in place the audio is perfectly clean.

Also, pins 2 and 3 on the USB jack are soldered together so your phone will recognize this as an "AC" power source rather than a "USB" power source (which means it draws more current and charges faster).

Using this to split the audio off from a ChromeCast to an external sound bar in my office (HDMI going into a monitor with no audio capabilities). using the RCA outputs.
Works exactly as advertised.

Now we stream whatever (and I can mirror my phone's screen) to the wall mounted display with full audio.

Love it; audio enhancement, beautifully designed. Anker has hit a sweet spot of audio quality with price efficiency.

Sleek design and does exactly what I need it to

Does exactly what it says on the box. Sound quality with an AAC-capable phone is as good as hard wired and far better sounding than the more expensive Grom adapter I used in a previous car which only supported SBC. Good output level too; this has no trouble driving the aux input on my stereo (Subaru McIntosh) at full volume whereas the headphone connection on my phone struggles to manage this.

I love the short cable and compactness of the Firefly's design; it hides away beautifully in the center console where the aux and charger connections are without taking up any room for other items. It emits a constant white light while connected that is bright enough to be potentially distracting if it were in the driver's view at night, but as this is tucked away in the center console compartment it's not an issue for me. Incidentally it serves as a useful illumination source for the compartment!

 There is very slight engine noise if I turn up the volume on the radio to max and don't have any audio playing, but during normal use it's completely unnoticeable and much better than any previous adapters I've tried.

Perfect sound solution for a room, great sound, and long battery life.

This unit, along with the "Panel Mount 3.5 Plug" allows me to play my iPod or cell though my traditional American Manufacture Automobile sound system.

It works perfectly.

I hid it behind my glove compartment and secured it with plastic cable ties to the heater / defroster ducts.

Glove compartment came out with two screws.

Then......

All I had to do was find a discrete place on my dash to bring out its connections. So I had to drill and then to install a tiny on / off switch (Came in the package) and the 3.5 plug, not in the package, to make it more Apple product connectable.

And away I go for many hours of my music.

Highly recommended.

Even a 12 year old can install this, as she did.

Because of the lack of audio ports included in modern technology, I finally needed a solution that would provide me a way of getting sound to any of my external speakers.  Having used this product for a while, I found it does exactly as needed, and have not noticed any latency whatsoever.

I couldn't be happier. This suits my needs perfectly, and in spite of the microphone being somewhat far away it picks up sound quite well. Maybe too well, in fact, because it can pick up my fingers drumming on the desk in frustration while waiting for something else. ;]

I had been doing so much research trying to find a portable speaker that would be able to play music loud enough in my back yard while my daughter played and I did yard work.  I already had a portable boom box, but it did not have the aux in option.  I am very pleased with this adapter, now I can plug my IPhone in to the boom box and have the sound volume I needed and use my existing piece of equipment.  It was such a minimal cost I figured it was worth a try.  It works perfectly to serve my need.

I have no complaints in using this device to process coaxial output from my Sony BDP-S370 and transmit audio to a small set of Logitech speakers.  I normally only have the device turned on when being used, and I have had no issues.  This product works well, especially considering the attractive pricepoint

Just what I needed, great price too. Love the custom color feature. Love the USB ports, both will charge my iPhone 5. The bluetooth is cool, but it's unfortunate that it takes up one of the USB ports, and it doesn't fit flush in the front port. The bluetooth also did not recognize audio files from the official Apple Podcasts app, but that app sucks anyway so I deleted it; loading my podcasts from the Music app works perfectly. If you have a lot of music/podcasts by different artists, etc, I find it slightly clunky to navigate to what you want to listen too. If you want to constantly change what you are listening to it would be a pain. Also I could be wrong, since I don't listen to the radio much, but this has no dedicated radio preset buttons, they may be hidden in a menu, or there might not be an option for them?

My car has bluetooth for calls but not media audio, but it does have aux input and a powered USB port, so it's well positioned for this device.  The setup was very easy - after plugging it to USB, it goes directly to pairing mode and my phone found it right away.  It's worked consistently, the 3 buttons work to play/pause, fast forward and rewind audio as you would expect, and the sound is very clear for both podcasts and streaming music.  I've kept my phone paired with my car for phone calls, and in the phone's bluetooth settings I've indicated that the car connection is to be used for calls and the soundbot for media and it connects to both simultaneously.  This is as close as I can come to having built-in bluetooth media audio without the big $$.  The charger is a bonus which I'm not using and will probably gift to someone.  I was sceptical with the low price of this device but so far (about a week as of this review) everything is working great.

1)  for what I paid, I got exactly as I expected
2)  works great with my new iPod nano (6th gen I believe) AND works with my old-style 3rd gen
3)  The size (for my small-ish car) is perfect...also the long cable length means I don't have to look down to change the playlist while driving - I can hold it up to my face
4)  sound quality is exactly as I expected -- look folks, lots of complaints in this area.  if you live in a highly-populated urban area with lots of radio stations, you will find it difficult to find a perfectly unoccupied part of the FM spectrum.  However, on road trips, where most of it is out in the boonies with 2 total radio stations both playing Christian rock, there is no end to the amount of available, staticky FM spectrum over which to broadcast your iPod's music

My only problem is that the 12V receptacle in my ar is "low", and causes the cable that connects to the iPod to bend at an unnatural angle.  I fear this will break sooner rather than later.

This is a great value; snap it up as long as it's still available.
