Actually I really like this, price not withstanding. My 2 year old just broke my 2nd Plantronics 510 Voyager so I figured I'd get a cheap one the 3rd time around. I'm really surprised how much I like this. Sound is great! Distance signal not. I can go about 30 feet before hearing bad static. It's either crystal clear or loud static. Volume up and down is a little irritating as when you change the volume setting, it makes a little beep which blots out for those brief seconds what the person on the other side said. Comfortwise amazing. The 510 Voyager is bulky around the ear but light in the ear. You really felt the weight which got painful or irritating after a long talk time of 1 hour or more. With this one, the weight around your ear is nothing. The "bulk" of the weight is what goes in your ear and it's quite light at that. It's a little different to get used to, like there's water in my ear that I need to shake out but I'm sure it's just something to adjust to after time. I'm not on my cell phone all day for business meetings or anything but I spend long times on the phone as a mommy who is trying to do a million errands or phone calls while taking care of a toddler and infant. Ever tried crawling on the floor picking up Cheerios or running after a toddler to get him dressed while trying to schedule doctor visits at same time? For all the running around I do while talking/waiting on the phone, this thing stays PUT with no problems.
