Excerpt: These sound fantastic and are an excellent choice for mixing. Not particularly boosted in any areas that I can hear. I also picked up a Focusrite Vrm box with these headphones to use for referencing. So far so good. I think its and excellent pairing and my mixes are translating to my monitors and consumer stereos very well.
Summary: Firstly, to give you a little background, I record music for a living - but I don't consider myself an audiophile. I bought these hoping for a headphone that was a little more "Hi-Fi" then my current go-to pair - AKG K271's, but I also own some Westone 2's.
These have delivered in every area except one (I'll come to that later).
The included case is very nice, I appreciate the included extras - especially a second pair of the felt ear covers.
Summary: Sound quality:
I must say that I was quite disconcerted by the sound signature of these headphones when I tried them first. I was not completely happy with what I was hearing, and despite the fact I was impressed by some of the qualities of the headphone (very detailed), especially when using a good source like the Xonar Stx, I felt frustrated.
Summary: These headphones should be valued for providing an ultra-bright sound signature not offered by any other headphone that I'm aware of.
Comparisons with the HD800: If you compare the 30hz and 300hz square wave measurements from the innerfidelity charts between these and the Sennheiser HD800, you'll see that the two are almost identical. I own the HD800s and this, and I can say that the SRH940s are much much closer to the HD800s than their prices would suggest.
Pros: Detail. Accuracy. very bright (if you like that)
Cons: Headband a little uncomfortable. very bright (if you don't like that)
Excerpt: Very comfy full sized headphones. It provides decent isolation and great details and is very neutral. Frequency range is very wide giving nice treble as well as bass details. Slightly less upper bass compared with srh440 and srh840 but the extra detail made me want to listen to my music all over again. The angled oval earcups provide much better fit and isolation then round cups like the srh550 and srh750, especially for average to small head.
Summary: So, I received my Shure SRH940's on September 7, 2011. Yay!
This is my first time posting a major review of an audio product and it addresses many of the questions I had when I was searching for my next major headphone. I hope this review is useful to both newcomers and veterans of Head-Fi. I am still learning about all of the technical terms and details of how to describe a headphone's sound signature, but I will try my best to convey my thoughts.
Pros: Comfortable, detailed/clear highs and mids, deep low-bass, excellent for: orchestra, classical, jazz, vocals, and certain kinds of pop and rock music
Cons: Mid-bass could use a tad-bit more 'oomph' without using an EQ, slightly fatiguing, poorly recorded or mastered tracks sound bad, headband cracking
