Best wireless headset out there for the price.
I have the black B2 Bluetooth model with the plug in bluetooth dongle that has its own internal battery. There's also a battery in the headset that powers the ANC circuitry. I've only used them a short time and I absolutely love the sound quality and the noise cancelling ability of the Jazza. I've never had an ANC headset before so I have nothing to compare them to. But I can say they are very efficient at shutting down ambient noise around me. I will be taking them on a long airline journey in June of a total of about 34 hrs. I will add to my review after this trip ONLY if I find anything negative to report. The instructions were written by someone with a poor grasp of English. The only delay I had in utilizing the Jazza was pairing it initially. Poor directions. I figured it out from reading someone else's review. Followed his guidelines and it paired perfectly. Hold down the center button on the dongle until you get a flashing red / blue light. This takes up to 5 seconds. If the headset is on, you can hear the audible signal in addition. These are so worth the $99 I paid for them. I hope they never die! As a personal note, you can't listen to music unless the switch is in the on position. That also means the battery has to be charged to listen to music. In addition, I think the wireless mode produces a better sound quality than the hardwired version. They also fit very comfortably and are quite light compared to the head set I am replacing. Nice case, cables (gold plated ribbon cables), and accessory airline plug. I can almost guarantee you won't find a better deal for the price. Haven't tried to take a phone call yet. But, I have no reason to believe that will be a problem. I say that because everything else works as stated. I'm a happy camper!
