There are a few out there but no where near as many as at other airlines. Our FOM says we must have a TSO approved headset. The UflyMike is TSO'd but I believe the way they got it was to have ear buds that you put on underneath the headset so you can still receive communication if your battery goes dead. I you use the UflyMike without those earbuds...........

I got a Telex 850 and it works great. It's good for international too. The noise canceling allows you to hear foreign controllers better plus you don't need a battery. I got one with both earpieces vs. the one with one earpiece (again it's better than one for international) and just fly domestically with the one pushed behind my cross cockpit ear.

Plus, if you don't already have the bose headphones, the price will probably be close. I got my 850 off of ebay.
