3.0 out of 5 stars
Perhaps best suited for special situations, November 6, 2008
I purchased this unit specifically for use with Dragon NaturallySpeaking 10 Preferred. In particular, I wanted it for use in relatively high noise locations like cars at expressway speeds, airport terminals and the like. It was also recommended by Nuance, the publishers of Dragon Naturally Speaking.
I am returning the unit for a refund. The negatives of the B250 are, I think, greater than the positives. For people in special situations, such as truck drivers, who can deal with bulk of this unit, because they are in the same place for much of their work day (the cab of their truck) or office workers staying in one place, the B250 may be fine.
For my needs, though, the B250 is far too bulky. It would not last long being pushed into a roll-on, messenger bag, backpack or other carrier. The simple metal headband would be quickly twisted, bent or destroyed. The boom for the microphone doesn't look like it would stand up either.
Pairing is just plain ridiculous. You are required to 1) hold down a button, 2) until lights begin to flash, 3) listen for up to 15 seconds for 2 series of tones followed by 4 more tones and then 4) release the button. And all this is after as shorter series of steps. (Oddly, there are two separate sets of instructions for pairing with a Bluetooth device, both with distinct instructions; i.e., one saying wait for 2 tones, the other saying wait for 2 tones followed by 4 more. Confusing, to say the least.)
When more than perhaps a foot away from my ear, I could hear nothing from the headset, which rendered this process impossible for me. The pairing process also proved to be erratic. Sometimes it worked, sometimes it didn't.
Charging times struck me as far too long. The first charge, according to the instructions, must be 16 hours.
I tried some tests of the noise cancelling features, turning up the radio and television. Noise suppression was okay, but nothing spectacular. There was no significant difference in the recognition of my words by Dragon when using the B250 or other Bluetooth headsets with noise cancelling features.
On the whole, I don't think the B250 offers any significant advantages over other quality noise-cancelling Bluetooth headsets, I think for those who are sitting in one place throughout the day, such as the cab of a truck or an office, the B250 would be more comfortable than one of the smaller, loop over the ear or in the ear types. But for someone on the go, the unit is just too bulky. And pairing it is a major bear, substantially more difficult than it has to be.
