Excerpt: These headphones are pretty great. They're very clearly intended to be used as monitoring headphones, which is basically what Shure advertises them as. They have a very neutral sound to them, and they don't try to make the music overly musical like my Grado 325is do or exaggerate the sound stage like my AKG K601s do. Something I've been sort of surprised about is how much isolation these headphones provide.
Summary: The Shure 840, which retail for around $150, is a very faithful reproducer of one's LPs, CDs, and portable bits. They offer no exaggeration, good build quality and a fine warmth that does not offer any kind of bass boosting. If you prefer a sound that has the low-end, er, pronounced as one finds in the Beats by Dre line you will probably not enjoy these. They sound ruler flat.
Summary: I bought these to use mainly for listening to TV & Music late at night. They work very well for this purpose with the exception of the 3.5 plug being a bit large so it doesn't fit my iPhone (that I use around the house when listening to music) when I have a case on it. I bought a small adapter at Radio Shack and solved the problem, so now I'm good to go! These phones are very comfortable and I can wear them for long periods of time with no problem.
Excerpt: I compared the srh840 and srh940 side by side. They both very light but the 940 is more comfortable thanks to being slightly bigger (so it doesn't touch my ears while the 840 does) and the material used in the hearpads feels a lot better to me. Build quality wise they seem to be even with again the 940 taking the lead since it doesn't have the driver cable exposed like the 840.
Summary: I just received these headphone. I put them on using my ipod outside at a Barbecue. As i put them on for 10 seconds and started to jam THEY FELL OFF AND LANDED IN THE BARBECUE PIT !!! BUT THEY SOUNDED HOT WHILE THEY LASTED VERY HOT .I WAS WONDERING IS THE WARRANTY STILL GOOD !!
Pros: HOT HEADPHONES !! VERY HOT !!
Cons: MAKE SURE THEY ARE TIGHT ON YOUR HEAD BEFORE YOU LISTEN !! AND STAY AWAY FROM BARBECUE PIT'S !!
Summary: These headphones are fantastic! My best pair of headphones to date. They have a rich, mellow, buttery sound that is a pleasure for the ear. Maybe they can be too soft for some, but for me it's perfect. They excells most with vocals, classical and jazz or acoustic instruments, but also with any genre of music. For example, Dance/Trance/Hip-Hop is very fun to listen with them. The bass go very deep with the right amount of impact.
Summary: The SRH-840, top of Shure's first line of headphones, is perhaps the best bargain in mid-level cans out there today. With an MSRP of $199, and a street price significantly lower, it can hang with cans costing three or four times as much. The best aspect of the 840 is its' balance, which allows it to approach all kinds of music and listening tasks with an even hand.
Summary: These sound like you are in the studio with the recording artist. They are great for digital devices really help make the sound come through. I own a pair of Dr Dre studio and I believe that these headphones sound just as clear. Nice tone with the bass, great stereo effect, great mids and the highs are almost ear piercing overall great set! Very pleased!!
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.
They have the incredible Shure warmth and vocal clarity, but still extend their highs extensively.
Pros: Weighty, firm clamp, massive earcups. Shure sound, replaceable one-sided cable, great build quality. So cheap.
