I know there have been a lot of other threads with impressions about these headphones, but I love them, and I needed to say why to someone else who would understand.
For reference, I am using these with the SRH840 Pads, powered through a Creative X-Fi Fatal1ty Titanium & Behringer Xenyx 1202FX Amp/Mixer.
So lets go!
First off, Comfort. A lot of impressions said they felt these headphones were heavy, or the headband was painful. I've been wearing mine hours on end since I got them and I haven't experienced any discomfort with the headband, or the weight though to be fair I am used to wearing a PC Headset most of the time and they usually run heavy. Also the SRH840 Pads make a huge difference in the pad comfort. The memory foam makes them squishy and feel like they're not even there.
Isolation: Again the 840 Pads help with this, but they isolate outside noise to the point my wife has had to come to the top of the stairs in the office and pound on something before I can hear her at all. She was not pleased she had been screaming up the stairs and I couldn't hear her.
Sound Quality: AMAZING. This is my first pair of professional headphones but they are so crisp and crystal clear it's hard to believe. The Highs and Mids ring true even over the ample bass. I know there are a lot of people who seem to feel this set is lacking in the bass department. I am not a basshead, but I have listened to several bass heavy albums (the Dubsteb Saved My Life mix CDs, Nicki Minaj - Pink Friday, The Marshall Mathers LP, Dre - 2001) and there was plenty of bass to go around.
They also fair very well with quieter pieces (Iron & Wine - In The Reins, Crosby Stills Nash & Young - So Far, Andrew Bird - Live in Montreal). With Andrew Bird - LiM I could actually hear as he hit the pedals to start and end loops of violin pieces. I could hear every snicker and whisper from the audience. I could even hear him quietly counting time to himself between loops. I'd never been able to hear that on any set of speakers or headphones I own.
They're also a great set for rock (Foo Fighters - Wasting Light, Incubus - If Not Now, When?) Vocals shine through heavy guitar with no distortion and no single part drowns out the other. Every aspect of the music seems perfectly balanced at all times.
Overall I couldn't be happier with these headphones, and can't wait until I can afford a pair of phones that will make these sounds bad. Thanks again to the community here for helping me make a great decision, and I'll be updating this with impressions through my Samsung Epic 4G w/ FiiO E5 tomorrow evening!
My FiiO E5 Arrived, and I'm listening to the 440s with the amp right now. I know the E5 is a very entry level amp, but even for the 20 dollars, the little nudge in volume and bass that this amp gives really makes these cans shine even more. Mids and Highs are more defined, and bass has that added THUMP that seemed to be missing before. I'm glad I picked this up as a starter amp, and I'll certainly be picking up the cmoy omap2227 amp I want asap! If a starter amp like this helps, I can't wait to hear a decent amp power these cans. It just makes me want the 840s that much more. Soon...
