Hello Mark, Here is what you are looking for, I used these for many years earning a living. They are called "Dual Headsets". One ear goes to your telephone, which has a small special box in-between your telephone and the headphone jack, which allows you to control tone, volume, mute and such, while the other ear goes directly to your computer where you can hear your JAWS. In every company I worked for, Humana Health Plans, The Miami-Herald Newspaper, American Bankers, this is the Brand name of the Head Sets their Customer Service Intake people used, the only difference being I used a "Dual Channel" set, while the sighted folks used one channel sets. The headset has a boom mike, it looks about like a coffee stirrer which you speak into. They are made of the highest quality material, very durable, yet very comfortable, adjustable, they will send you parts, like the ear foam cushions that get old after a year or so, immediately with a single telephone call to their parts department. Well, they are the top of the line. And the price expresses that also. *** Plantronics United States - - Information on Products and Services Toll Free telephone number 1-800-544-4660 Telephone number (831) 4426-5858 Fax-on -Demand Address: 345 Encinal Street Santa Cruz, California 95060 Toll-Free: 890.544.4660 Prompt 4 Direct Dial.- 650.598.4330 United States - Information an Products and Services CHOOSE PLANTRONICS Sound Quality 170 Coiiifort and Part number 15729-05 SKCCommunications Inc 1-800-882-7779 oice Tube 17593-01 Model number Dual Channel Head Sets Jan Ext# 0 ID 5461 If I can help let me know!
