Honestly, think about how much you paid for what you ended up with. For those of you who were worried about the 940 being an 840 with a new paintjob... fear no more.
Not gonna lie, although I realized the quality initially I still only thought "meh". As I spend more time with them I really find them growing on me. For me I really didn't find them as much of a shocker out of the box (or after some break-in) but it is very obvious that these deliver a type of sound any audio enthusiast has to respect... even if it isn't a preferred response. I'm finding these house the type of response I prefer (smooth highs, present mids, tight/fast recovery bass.
I'm becoming addicted to how large the vocals sound without a hint of harshness, and am still the most impressed with the ability for the headphone to extend without compromising quality. Kudos Shure Audio, you've impressed me (esp. at the 300 dollar pricepoint)
My only real complaint now comes from the headphone physically. I can't do multi-hour (3+) listening sessions with these headphones like I can my SP-1. For me they do get a little heavy on the head and I feel pressure from the headband after an hour or so. I'm aware that this was a common complaint for the 840 and am aware that the 940 is probably a vast improvement in comfort over the 840, but I'm still finding flaws. It sounds beautiful enough for me to tolerate it for at least a couple hours... but it'd be nice if I didn't have to. I guess I'm kinda spoiled with my pillow fit SP-1 and HD 448 - clamping force is near zero it seems and the weight is a joke it's so light. I'm probably just being a baby
