My pirep may be dated somewhat because I have 3 sets that are all with the previously available qc15.
I have a wife and kids that absolutely despise the head clamp. My goal was to find a super comfortable headset with decent ANR that they enjoyed wearing without breaking the bank in a crazy way.
So I gave the uflymike a shot. $225 for the uflymike. I'm an eBay guy so $100 gave me a nice lightly used set of qc15's. So $325 for the headset.
How does it compare?
1- comfort - wonderful! Super light weight and extremely light clamp. Blows away the $1,000 Bose and lightspeed models in this category.
2- ANR - excellent. Crystal clear. If anyone complains that it blocks out less sound that the high dollar sets- refer back to #1... there is a *slight* tradeoff for less compression around ears.
3- durability - B+ - The one fault in the ones I have is that the mic does not swivel and lay flat against the headband portion when not in use. I have 3 of the uflymikes and none have broken yet though.
4- power - aaa battery required. They last many many hours but they will still eventually die. I keep a box of batteries in the plane. Nbd but see summary.
5- value - A+
So after all that I will say that I do not use a uflymike as my primary PIC headset. I use Zulus that I also bought on eBay for about $400. I don't mind a heavier more clamping headset personally. I also don't want to worry about batteries if I'm talking to atc... the uflymike does NOT go passive when batteries die.
So essentially I have 3 uflymikes and absolutely love them. They are A+++ for my pax / kids / etc. Can NOT be beat. They could be used for PIC no problem but for that specific purpose realize they have sole minor weaknesses compared to standard ANR aviation headsets.
Good luck.
