After reading so many different reviews about so many different headsets, I decided to go with the Plantronics Voyager 510. My only hesitations were it's age and it's design. But, in the end I told myself that this one has gotten thousands of reviews and its average is still waaayyy up there. Let me tell you, this particular model works as advertised.Pros:Distance - It gets staticky around 25+ feet. Awesome!Clarity - I can hear the calls clearly because of the in ear style. Plus, people on the other end can hear me even when it's windy.Comfort - My girlfriend is constantly taking it off my ear because I forget that it's there.Versatility - I use both ears. My right side is preferred, but I use my left when I'm driving other people.Neutral:Battery - I really haven't gauged the timing of the battery life, but I'm not complaining about it.Cons:Design - It looks too funky, but for all of the function-over-form people, the 510 works great!Mic Boom - Because I have a wide face, the boom sometimes swivels in and touches my cheek (I hate anything touching my face unknowingly)Since purchasing this headset, I've tried 2 others, the Samsung Wep200 and the upgraded Plantronics Voyager 520.The Samsung was purchased for the girlfriend because its tiny structure was appealing. She complained that it wouldn't stay on her ear. I tried it and agreed. Also, it's clarity and distance was subpar relative to the 510. I ended up giving it to my brother.The Plantronics Voyager 520 was also purchased for the girlfriend because the Samsung didn't work out too well. She's making me go broke! I was honestly excited about the 520. After all, it was the latest and greatest. Latest it is, but greatest it isn't. It doesn't have different size ear buds like the 510, but luckily it fit her ear. (phew!) Distance is horrible. I can't go more than 10 feet without getting static. The size of this thing is a little on the HUGE side, but I still think it looks better than the 510. It's noise cancellation works like the 510, which is one good thing. Bottom line, if it wasn't for its poor performance with distance, my girlfriend would have loved it AND I wouldn't have to return it and find her a new one. The things I do for that woman! If you're reading this, I still love you hunni! :)Conclusion: If it wasn't for the 2 Cons factors, this headset would be perfect for me! But relative to its replacement the 520 and the Samsung, this model is hands down THE headset to get.
