Alternative is to have the KB unit (or HKB for HelixNet) integrated into the armrest to allow for talk-switch and volume manipulation as well as channel choice if the arm rest is large enoughIf there is an option for a chair with a large enough armrest that doesn’t have integrated speaker and microphone. then use the KB as normal (i.e. gooseneck sticking out of the armrest)
