Summary: Hey. This is going to be a review of the Shure SRH840. Now, these are Shure's 3rd headphone in the '40 series. They are for everyone, including regular people and studio professionals.
To start off, i am going to talk about the overall value and what you get when you purchase these.
Pros: Smooth sound. Good build quality. Comfortable
Summary: Shure SRH840, are a value filled set of extraordinary headphones, worth every single coin you spend on it. The bass register is perfect for any genre of song you play through you phone/computer/mixing desk etc.
Pros: Fantastic EQ balance, very good for recording and return sound.
Cons: Nothing, except headband can be slippery and sometimes falls of easily.
Summary: So I'm not going to try to impress you with my resume or be unnecessarily verbose here...
I'm having a little trouble justifying the purchase of these cans after a few hours of playtime - I'm not a staunch believer of burning in, but I'll give it a shot and amend if there is a change.
Summary: After burn-in and listening to them for a hundred hours or so, plus live mix time this is my perspective on their audio.
Coming from Sennheiser HD280 Pros and Shure SE215s, these seem to be amazingly balanced.
Pros: Weighty, firm clamp, massive earcups. Shure sound, replaceable one-sided cable, great build quality. So cheap.
Summary: I bought these about a six weeks ago for $180 at Guitar Center (They retail for $250, and I have since seen them for $160) after reading a number of stellar reviews and trying them out in the store using my iPod.
Pros: Consistent across the spectrum; Great bass; Extremely revealing; Very efficient (can drive easily with an iPod); Relatively modest price
Cons: May not be the best for full orchestra classical (which I don't listen to much)
Summary: Disregard my earlier hate for these have come to appreciate these for what they are.
To start off my review i would like to say my opinions on comfort with these. Lots of people complain about them being uncomfortable or heavy, the truth of the matter is they feel rather light to me.
Pros: clear sound, comfort, perfect bass, good midrange, good highs, around the ear design
Cons: durability, very revealing, sibilance, strident upper mids/lower highs can be a little annoying
Summary: For less than $200 you won't find a better pair of headphones for studio use. I wouldn't recommend these to anyone who isn't going to be using them in a studio. You can't really take them with you and there's much more "fun" hi-fi headphones for home use.
Pros: Very flat sound across the board, reliable for checking mixes, build quality is there.
