Just wondering here. Still playing around whith the new machine and i have found a slight problem with the headset. I seems the headset cord is a little short for me. Im 6,3 with long arms. This is with the control box mounted under the cuff. It seems to pull on the phones when i swing it. I cant use it if mounted infront of the handle. Down the road if i bought a set of aftermarket phones could i send it in to Tesoro and have them put them on?
