To start off, I know there have been multiple forum posts about this exact topic over the years, but none really answered the question I had, so thought I would start this as a fresh one.

I (tentative I pass training) am going to be a CRJ driver now. I currently have the Bose A20, and just have gotten tired of them. They feel heavy and I get a headache if I fly with them for more than 4 or 5 hours in a day. Yeah they were nice when I was flying in a Cessna 172, but I have heard that CRJ's are pretty quiet.

I am in between two headsets right now and wanted some input. First is the Telex Airman 850. They are super lightweight and still ANR. Second is buying the Bose QC15 with the UFlyMike attachment (saw they don't have an attachment for the new QC25 headset yet). They are 5oz lighter than the Bose A20, cheaper, and I can take off the microphone and use it to listen to music outside the airplane.

Anyone have any pros/cons on either.

Just wait till you get in the plane. You can also ask the other pilots.

DC pro-x. It has anr and Bluetooth. Very crisp and clear. Also lightweight. I don't get that clamping feeling.

Bose recently released the QC25, and uFlyMic states on their website that they're developing a mic for it. I'm waiting for that, then I'll upgrade from my Zulus.

David Clark H10-13.4 / solid, comfortable, and reliable.

And painful. You forgot painful.

The airline doesn't supply headsets?

The ones I've seen are worse than the green DC head vises.

850 best overall long term choice. DC pro-x if you want better anr and Bluetooth connectivity. I've had both plus the clarity aloft. If I was back on a jet as quiet as the crj...I would get another 850.

I'm currently using the pro-x, and it is a good headset that needs a few more model years to get the kinks worked out. Not as comfortable as the 850. Bose has better internals, but I can't stand them on long flights.

QC series is too much hassle for me. Some people swear by them.
