I’m sending mine back. The cord is shockingly heavy. Good for durability but if you don’t have the means to secure it with the clips or don’t fully unload the weight of the cord off the headset, it makes it unbalanced and uncomfortable. The cord also comes straight down from the microphone side so I found it touching the side of my face and neck. Maybe some won’t mind that but it was a nuisance and made it awkward turning my head and always running into the cord.
The ANR was solid for the 737 and the pass through feature is truly unique and beneficial.
All this said, I am one of the few users that went from a lighter headset (Clarity Aloft) to the Pro Flight. The added weight was noticeable and I find the in-ear plugs from the CA more comfortable than the Pro Flight ear tips. Also, the passive noise reduction is almost as good as the ANR on the Bose...with the added bonus of no batteries.
I know a lot of my complaints are subjective but I just wasn’t sold on it.
I’ve got my eye on the Clarity Aloft Flex next.
