I bought the Motorola H700, Motorola H500, and the Jabra JX-10 to see the differences. This is what I found:Jabra JX-10: sleek and cute design, small, costly, way less static than the Motorola H700, earpiece that sits inside ear is uncomfortable after talking about 45 minutes (I have small ears), headset doesn't flop around when I'm walking or bending over due to the earpiece that makes it stay put.Motorola H700: lighter, small, cute, more static than Jabra JX-10 (both close and far range but still within 10 feet), more comfortable for those who hate anything sitting in ear, not recommend for bigger/wide facial structure because the close/open call piece will be against your cheeks, headset flops around a little bit(way less than Motorola H500)but won't fall off even with my small ears.Motorola H500: wouldn't recommend after using the above devices, cheapest in price, only good if not too picky with sound quality and level comfort, overall it's decent.I also walked away from my palm 700 and close the door with both headsets (about 8 feet) and the Motorola H700 had static and the other person couldn't hear me well. The Jabra JX-10 had only a little static with the other person still being able to hear me.It really comes down to preferences and what is important to you when looking for a headset. I am going with the Motorola H700 ONLY because I prefer being comfortable over sound quality. If objects in the ear doesn't bother you, I would highly recommend the Jabra JX-10 instead. It's higher in price but way worth it. Keep in mind that I never liked the headsets they give you with new cel phones because they felt uncomfortable after talking more than 1 hour. Hope this helps!
