After researching their website, it looks like the UFM adapter with the earbud (the only way it is TSO'd) is $300. the Bose QC2 headphones according to Amazon are $300 unless you get a used pair. That's $600! You can get a set of Telex 850s which are unquestionably TSO'd for about $400 new. Doesn't sound like it saves you money at all really by going with the UFM.
