The Mobile Freedom Headset had very good sound quality, volume and reception - even in the wind, and the part that sits against the ear was comfortable. However the over-the ear part was uncomfortable to begin with, and became painful as the day went on. Nothing I tried helped, and I finally decided to just send it back.If Logitec made this unit comfortable, it would get at least 4 if not 5 stars (depending on how comfortable it turned out).This is the second BT headset I have tried, the first being the exceptionally comfortable Anycom (see my review) that would not stay paired to my phone. Right now I am trying the Jabra BT130, and I will write a review after I have used it a while.
