Hooked up to my Bose computer speakers and it's working great.

The audio and microphone works great from my phone to my car's speakers

This thing is great works flawlessly in my car and my girlfriend likes it because it can allow her to use any headphones with her iPhone without the adapter

This works great to play music from my iphone in my 2007 Honda.

after leaving this comment, the vendor sent me a new one and is working great so far.

Product is perfectly good, works as intended and at a fair price

It is a great price but it doesn't work.

:/ fixed my mistake, and total price of system is still pretty reasonable, maybe $75 including $9 audio cable to connect aukey to sony radio

I can’t speak on battery life, but the sound quality is good, and the price is great

The price is great and a big upgrade from the cables I was using before

If Aukey can't make it right, I'll find a replacement.***UPDATE***AUKEY absolutely made it right - shipping me a replacement

Battery life has not diminished as much as I would have expected over time, and even the microphone still works just as it did on the first day as well

Greetings, I am happier to be able to buy AUKEY products from the packaging to the article, it's a wonder.100% Recommended thanks AUKEY

The internal amplifier is strong enough to drive a pair of headphones as loud as if they were connected directly to the phone and the music quality is excellent

Aukey made good on their product by sending me a second one when the first one I received wasn't working.

connection was flawless remember this is a standard volume level headphone sound is great no static or cut outs no delay .. now what everyone wants to know but are not posting started work at 3:30 am turned it on played music from my phone ( had to connect a battery to my phone to keep it powered) but the Bluetooth device was running on my portable speakers for my full 8 hour shift no drop or cut out all from one charge so if i was asked should i buy this item i would say hell

It did was it was advertized to do, amazing sound out of my system (4 speakers and base)

Got some super nice surround sound speakers, but they are just a little outdated and don't have bluetooth

The only drawback is the device does not power on automatically when connected to power, and since it has a battery it is not a good option to use in the car since it will stay on until the battery dies.

To use those audio jacks without connecting the iphone and still have the iphone on charge all the way, you need this cool little device

so this was a fun experiment that netted me a very capable device I'll want to keep

its the best bt device that I've used in a long time well worth getting to make you speakers bt

For my purposes, this makes the device dysfunctional and completely useless.

I use it almost every day, and the battery life is great.

Battery life has not diminished as much as I would have expected over time, and even the microphone still works just as it did on the first day as well

so battery life is never an issue for me.

They work flawlessly, easy to install, comes with everything you need for multiple applications, and the battery life is unbelievable.

It works great, the battery life is pretty solid and really have no complaints at all!

works as advertised no issues yet expect for automatically disconnecting at times.

Only had it two days but unless something happens to change my impression, this item works as advertised

Great range, great sound, decent battery life, no dropouts, small size, no annoying pairing sounds, just a simple bleep

The range of the bluetooth transceiver is great, despite the steel blocking a good part of the antenna on the left

It makes it really easy to play music from your phone while moving around and has a decent range.

Super easy to connect through Bluetooth, great range and easy to use.

The feedback/warning sound is REALLY loud and obnoxious

This one has static sounds especially at low sound volume and comes from the left side

Great range, great sound, decent battery life, no dropouts, small size, no annoying pairing sounds, just a simple bleep

This receiver is hooked up to my home stereo and has surprisingly good sound

Good quality sound but needs to be a little louder to hear over my exhaust.

I could'nt get the think to pair at all...worse thing was that I couldn't unpair from the echo.

couldn't finish a workout with the obnoxious little thing

how well this thing does on phone calls using the built in mic

hard to get it to switch between call and speaker or however the dumb thing works

These are really great little devices that maintain a solid connection as long as they're in use.

The connection is stable and great, no weird stutters or disconnects like my old device

But I did not like loud irritating alerts it made through audio devices connected to it when connection was made or broken

Set up was easy but connection can sometimes be spotty.
