wireless mic or headset/mic recocommendation needed

[Joy Tilton]

Okay, I've a logitech H800, which is a decent headset.  However, the mic 
is so tinny, At times it causes communication issues with hearing 
impaired persons dealing with such things as tinitus when I talk with 
them over the pc.  Plus, for decent recordings, the mic does not give a 
rich enough sound

What would be a decent sounding wireless mic that does not cost an arm 
and a leg, something that can generate a more well-rounded sound?
