All, In December there were several posts regarding the 30-3G headsets. Looking at comparison charts, there is little difference between the 20-3G and 30-3G 4db ANR and $130. My only experience with ANR head setd was a flight with Jeff L and his DCs (about 1000 times better than my cheapies).
Has anyone ever compared the 2 lightspeed models and found anything that makes the 30-3G worth the extra $130 ?
