My computer uses a 4-segment plug for the mike/headset. I bought an adapter from Headset Buddy. http://www.theheadsetbuddy.com/ It's called a "PC Headset to 3.5mm Smartphone Plug" Item # 01-pc35-ph35 (obvious huh?) It works for me. They have more adapters thanyou can shake a stick at! NFI Yada Yada... -- Dave G KK7SS Richland, WA
