I had high hopes for the Jawbone. I love the aesthetics and I completely bought into the noise reduction technology claims. While it is an improvement in terms of hearing conversations and having folks here me (while walking on busy Manhattan streets), it is extremely uncomfortable. I've tried all of the different ear piece configurations and wearing this device for more than 15 minutes is out of the question. Given that most of my conference calls last an hour, I'll be looking for another solution.
