I also have a pt 655. I think it is terrific. it is the first headset I can hear. mechanics of ear install are similar to a shure headphone. very light. i do not notice a delay. some of the earlier models had delay complaints.

i have had no trouble plugging into the charger, once i learned right side up from upside down.

i've gone through just about every top of the line headset in the past 4 or so years. had a plantronics m3000. the m3000 will not work as a doorstop.
