Telex - Startus 50 D - Digital
Have been using it for about a year... and just great. Provides the best noise reduction.... they claim it's the only ANR that reduces noise in three ways.. Passive, Analog and Digital !
Needs 4 AA's to give about 20 hours.... But has a lead out with cigar jack which u can plug into anything from 8 to 24 volts.

Some want about $1600 for it.... Shop around and shall obtain for $1300...... Hint : YSBK
Colleagues use the DC's and they have a lot of troubles with battery power and two of them had troubles with some strange !! noises coming out of one earpiece within the first month. Them got replaced though.
