Wow, this is about the 7th Blutooth I tried in 2 years, and for the price at Best Buy ($75.00), this H500 was a letdown. Let me say that I really wanted to invest in a Motorola product, and believe it or not, this H500 looks good, has great reception (easy to pair with too!), BUT the major drawback is the earpiece design. This H500 does NOT fit well on my ear (which isn't small!), and the unit simply flops around without being secure...this is VERY IRRITATING!! Also, since the H500 doesn't fit well, you may have trouble hearing the person on the other end.You have to continually nod your head to keep the H500 from falling off, and don't even think about making sudden quick movements..the H500 will simply fly off your ear...so much for a $75+ investment! If I were you, I'd avoid this H500 in the store and buy an affordable wire unit from Jabra. The entire Bluetooth technology is a big letdown, so after numerous trials, I decided to stick with reliable wire units.BTW, I also tried a unit from Plantronics, which had a superior fit & easy pairing with my phone, but the unit's reception was AWFUL...STATIC GALORE & low volume on both ends!
