Clearer than their cellular sure. But is it crystal clear?
For what it is worth, I spend about 250+ minutes a day on may CDMA Treo650 on Verizon. It is clear as bell. Mostly conference calls, and no one ever knows I am on a cell phone.
I recently tried the Bluetooth headset, and immediatley received complaints about voice quality and background noise, so I am back to the wired headset.
I tried Vonage and Skype (9 months ago), same complaints about quality and background noises. Still, I used Skype for conference calls last year when I was in Aruba because the GSM phone I hade with me sounded worse.
