Want "wear all day" comfort, good sound, out and inbound, and easy operation?  This is it.  I've tried them all including a new "super headset" that is supposed to eliminate all background noise.  I felt like I had a foot in my ear and the performance, in and outbound, was terrible.  The H710 works great.  My only complaint is a non-replaceable Nimh battery good for only 400 charges.
