I was not able to get the bluetooth to work with my iPhone.  Very disappointed and haven't used it at all.

I bought this to listen to music from my Droid and computers.
I followed instructions but it would not pair with any device I tried.  I had 2 flashing blue lights signaling it was trying to pair.
I tried the Droid, and 3 computers 2 running Win 7 and one Linux.  They all saw each other and paired fine.  However this headset did not even show up in the list of possible devices on any of them.

Either I got a defective unit, or it is incompatible with my equipment.

It's a shame because they seem pretty comfortable although I didn't have them on for more than a few minutes.

Edit:  I returned them and bought the Kokkia (link below).  They worked right away on all devices.  Very good (not excellent) sound quality not as comfortable as these but at half the price I have something that works.

I do suspect the set I received was defective but I wanted something that worked and didn't want to track down problems.  If you buy this headset I hope have better luck than I did.

I got these headphones as a Christmas gift from my wife.  I paired them with my iphone and they worked great.  A week later, I tried to pair them with a blue tooth adapter that I have attached to my audio receiver.  It would not pair even after disconnecting it to the Iphone.  Now, it will not pair with any device in the house.  I have tried to contact support with no luck.  Because my wife bought these several weeks before Christmas, and I tossed the packaging, I can not return them to Amazon.

These sound great. I used them for about 3 months with no problems. I stopped using them for the summer (2 months). The problem is when I went to use them again they wouldn't connect to any device. They work perfectly fine but just refuse to even be detected by a Bluetooth device, iPhones to be specific. BUMMER.

Edit: The company responded quickly with great customer service and replaced my Bluetooth FM transmitter quickly with a working device.

Original:
After many attempts, it did not pair with my iPhone 8. I will return and buy a different brand.

Bluetooth signal is HORRIBLE!!!

I could not for the life of me make this work for Android. I changed the unit and tried every buttons. The bluetooth does not even see the unit.
Maybe I got a defective unit?

I cannot have any Bluetooth with this device. Gps works fine but no phone answering thought it is marked phone connected.

A bit disappointing...worked with my wife's iphone5, but my iphone 4 just refuse to connect with it via bluetooth.  When it did work, the sound was not as powerful and she experienced some lag during streaming.  The product's slick design and compact size are the only pluses.

Cannot connect via Bluetooth from iPhone 5c, sounds great when connected to earbud jack. Frustrating. Have used other Bluetooth speakers with no problem connecting.

Bluetooth just stopped working.  I contacted them and they told me how to reset, but that only worked once.  I tried the plug in but that did not work either.  A very expensive mistake.

The bluetooth did not work with my ipod, ipad, computers and android phone at all. The item could not be returned. The aux jack only worked with 3-pole audio cables and did not work with 4-pole audio+mic cables. I rated it three stars because I could use it as a speaker for my ipod and desktop with a audio cable.

Same issue as the last review....will not work with an iPhone since IOS11. Ive been on the phone with clarion customer support several times, and they apparently have no intention of releasing updated software.
