Other things to factor in.... Is space to store and carry the headset a factor? What's the environment you'll be flying in? Are there other features you want to have?

At my previous company, DC H-10-13.4s were standard issue flight deck equipment. They worked well and I liked them (and their price) so much initially that I bought myself a set. But they were less than comfortable when wearing sunglasses, especially for longer flights. They were also relatively bulky and finding good way to carry them was always a challenge. I tried a friend's Bose headset and liked it a lot but was less happy with noise intrusion from the ear seal gap while wearing Oakleys. Telex headsets didn't work - cockpit was too noisy for those. I found the best combination of size, portability, noise reduction, and features in the DC Pro-X. Headset was easily stored and carried and provided excellent ANR and clarity, durability, and nice other features (bluetooth came in handy making quick calls to dispatch or maintenance if something came up when approaching the hold short line). They are worn over the ear but the soft seals are still over the ear, not around them, so wearing sunglasses with them is not an issue. I really liked them.

These days, I'm back to a Telex headset, the -850. I fly a quieter aircraft and don't need quite as much noise reduction, though the -850 provides decent ANR. Also, most crewmembers don't use ICS but simply talk to each other over the center console and leave the inside earpiece either slightly or fully off their ear - and that's true in just about every fleet here.

All the choices listed previously are good ones. But what works and is best for you will largely depend on what features, capabilities, and such are most important to you ... And what detractors you're willing to live with. Good luck!
