I purchased the Jabra Free Speak headset a few months ago and at first it was a novelity, but after using the device with my eye glasses on it was very uncomfortable and made my eye glasses tilt down so much that I either had to remove the headset or take off my eye glasses. As for the quality, I found too much static when using it and worst of all the battery or talk time was far less than 3 hours. All in all, the concept is great, but for people who wear eye or sun glasses the Jabra needs much improvement.
