After trying several Headsets in the $75.00 and under range, This Plantronics Voyager 510 I feel is the best.. Very Comfortable I wear mine 10-14 hrs a day and I forget sometimes its on. Very Clear headphone and mic, noise cancelling works very well even with window open. Only small flaw I would say is the Power button and Volume Rocker Switch can be sometimes difficult to operate. I tried the Scala Cardo as well as the Logitech . The Cardo sounded bad and very uncomfy . The Logitech sounded much better and did a great job with wind noise , however after wearing it for 10+ hrs a day it actually gave me a blister on my ear very uncomfy. I bought this Plantronics and Im buying another one as a spare. For under $50.00 you cant beat it! And Amazon Rocks with pricing and shipping. 75% of my purchases are made on Amazon.
