I have been researching bluetooth headsets for awhile and think I finally narrowed it down to two, the Jabra BT500V and Jabra 5020. Honestly I like the 5020 more since it's newer and maybe more features but the only thing I don't like is the BT500 series has the gel earpieces and different sizes and from what I read the 5020 doesn't. The 5020 seems more like the iPod standard headphones from the pictures I can see and I've never been able to wear those. I wear glasses and have been told both work well with glasses. The one major difference is the 5020 is bluetooth 2.0, the BT500 series is 1.2. Will this cause any problems for me or is 1.2 fine?
