I have confirmed this headset works very well with SmartSDR Version 1.4.3 and a remote laptop running Windows 8.1 in REMOTE mode. Used VOX for PTT and could walk anywhere in the house. The wireless link is 2.4 Ghz dedicated via a dongle plugged into the laptop. I received good audio reports on the TX audio.
Apple Earbuds with inline mic is an interesting alternative. Selling for about $30, my daughter gave me a spare free set. The earbuds are Bose quality, and the mic is getting me very good unsolicited audio reports. The 4 ring audio jack on my new Lenovo laptop is a perfect match connection. The earbuds are very comfortable and runners tell me they stay in the ear even while jogging. They are passive so no amplifier latency problems arise. Been just what I needed for my laptop/6300 remote operation! Bill, KI4B
