Query: Issues with A2DP Cell Phones in Bluetooth mode

This headset works well in general when you use the dongle provided. Sound is good for non-audiophile.Since it is using bluetooth protocol between the dongle and the headsets, you can actually pair them directly with a bluetooth device such as a computer that supports bluetooth or a cell phone.When I pair this headsets with my computers (one using Kensington Micro USB Bluetooth Adapter and another using Motorola PC850 Bluetooth Adapter), they are working fine. However, when the headsets are paired with cell phones with A2DP profile, the sound is cutting in and out. This is apparently is a known issue if you google "Freepulse A2DP".So, if you don't mind using the dongle, this is a good item. But, if you intent to use them with an A2DP compliant cell phone, I'd look elsewhere.
