Summary: i have been using plantronics products since i was a stock broker in the early 90's. since the inception of bluetooth products for cell phones, plantronics has offered a line of cutting edge products with the highest quality. this is my 7th plantronics product and have yet to find a better product at any price. i always compare my bluetooth with other brands that my friends get and they always convert to plantronics with their next purchase.
Pros: I wanted a small player that I could use while I was riding my bike (bicycle, not motorcycle) and would pair with my blackberry. This one worked and the music sounded very good even while riding with the wind..
Cons: I got the wire to the other ear lobe tied up in the bicycle helmet, but for me not that much of a con, as it's small size works well and is a plus - better I believe than larger units or one with a fixed band between the two ear headset sections .
Pros: Very sleek looking, functional extending boom. All functions work perfectly with both of my phones.
Cons: advertised TALK time is bogus.. I absolutely promise you won't get anywhere near 7 hours talk. best I have ever gotten out of this thing (right after a full charge) is 2 hours 37 minutes. The battery is junk, or just too small.
