Summary: All I can say is, I am glad I purchased these cans! I am not going repeat all of the technical aspects of other excellent reviews but I will add my 2 cents. I researched the HELL out of several brands and types of headphones before taking the leap on the 940s. Being a musician and currently owning the Awesome sounding Shure SE535s, I needed some cans that would the same EXCELLENT music reproduction.
Summary: I bought the SRH 940'S and by god there incredible headphones. The quality from the headphones is not at all like your really there, its more like you enter a whole different world when putting them on. The best way to describe it, is you are truly listening to the purest of audio. The 5hz-30khz response is no lie. Yes it seems a bit excessive, but you get exactly what you pay for. Ive compared these to the SRH840's, and the Sony 7506's.
Summary: Very comfortable, but a bit on the heavy side. Sound quality on good recordings very good. Running an amp makes a big difference. These headphones sure show how lousy most mp3 recordings are.. No regrets here.
Summary: My new Shure 940s are incredible! I normally use my Shure in-ear 530s, which I also find incredible but I wanted to try out a high quality headphone-and I was not disappointed. To my surprise, they both provide different presentations-the most noticable difference is that I found the 940s richer and slightly fuller throughout the entire music range on all types of music.
Pros: Absolutely everything. I'm used several other in-ear and headphones and NONE come close!
Summary: These headphones are astounding. I have never written a review for a product, however, the sound of these headphones inspired me to do so. I produce music and I have honestly never heard music sound this clear across all frequencies. They are absolutely perfect for recording, mixing, production or for just casual listening. I had the AKG K271 headphones for years and, to be honest, there is absolutely no comparison.
Pros: The sound is absolutely exquisite. Unbelievable actually.
Cons: The headphone band causes some slight discomfort on the crown of my head over time. I have to move it around to avoid continued discomfort.
After a whole lot of browsing, reading, testing, etc., a couple of years ago I decided on getting new cans. This resulted in me acquiring the Shure SRH440s. At the time I had not listened to such type of headphones, meaning quite balanced with great mids providing a complete package that actually made you want to keep listening and enjoying music. (I.e. most headphones I had were cheap Koss or Sony’s, etc.) These cans opened up a new world for me.
Pros: Great mostly balanced sound for recording, great package that includes all you need, removable cables, best “mids” I have heard out of any headphones
Cons: Not very portable, not the best isolation, no handle on box that encloses the cans and accessories, still bass-light (or too treble friendly ;-))
Summary: I was for the longest time skeptical on these. Following intently on the srh940 thread the reviews were varied. Some people just up and claimed them to suck and sound fake while others praised them. When i purchased these i was afraid the naysayers may be correct. I received them and they are so wrong. These are the best headphones i have ever heard. These are smooth, detailed, neutral, fun, and revealing in a way that doesn't ruin enjoyment.
Summary: I must say I also own Sennheiser HD 650, but since I bought these Shure, I find myself preferring them to Sennheiser.
For the price I have paid (218,- €), I couldn't find better sounding headphones.
For me, sound is perfectly neutral, nothing is overemphasized, they reveal remarkable detail nevertheless I can listen to them for long period of time probably due to their flat frequency response.
Pros: Perfectly balanced neutral sound, outstanding "mids" and "highs", fast not overemphasized hifi bass, great vocals, removable cable, carry case
Cons: bass is not so punchy as on some other headphones (but for me it''s not even cons)
Summary: These are some seriously transparent headphones. Being reference, they don't accentuate any particular frequency and can sound a bit flat when it comes to fullness but that is mostly due to not having a decent audio drive, i.e. high quality DAC, amp... These do 'open up' quite a bit after a thorough burn in so take a little time to do it.
Pros: Outstanding reference quality headphones.
Cons: Felt can get a little warm., Would like to have balanced inputs.
