There is a cheaper one on ebay but I think I want to try a single one so I can use it while normal carrying of my phone (may fit in the case I have).
Here is a single one on ebay
http://cgi.ebay.com/3-5mm-USB-AUDIO-ADAPTER-FOR-HTC-TYTN-II-8925-MOGUL-6800_W0QQitemZ160282609417QQcmdZViewItem?hash=item 160282609417&_trkparms=72%3A1163%7C39%3A1%7C66%3A2 %7C65%3A12%7C240%3A1318&_trksid=p3286.c0.m14

I cannot confirm that either of these work. If any of you have one that is confirmed to work with a 20273 Kitchen.
