SiegeXSRH940 to DT880: Starting from the bottom and climbing up the frequency curve, there is slightly less perceivable bass but equal bass quality--not a midbass hole as others have claimed but more akin to a bass roll off of 3-5 decibels, from 40 Hz to 20 Hz, dependent on snugness and position. Its midrange is very lifelike--a farcry from the DT880's slight U-shaped mid-reserved soundscape--certainly one of its highlights, a step up quality and quantity-wise. Its treble has a electrostatic-like quality just like the DT880, except without that model's polarizing ice pick curve and artificiality, instead actually extending further in airiness and spaciousness, a natural result of its control and finesse. Aside from its sonic fingerprint, its build holds up well under daily use and, being sealed, it passively isolates external noise so you can have an on-the-go audiophile sanctuary on the daily commute or 40,000 feet up. In the bundle, it also comes with a handy foam zipper case, complete with extra pads, a straight cable and a coiled cable, with room to spare for a Fiio E17 and perhaps a mp3/mp4 player inside.
I prefer the Shure SRH 940 by a long shot to the K701 and, by extension, to the SRH840 and certainly the K550. It is astoundingly very linear with a hair of excitement of 1 to 2 decibels of treble in the 8 to 14 kHz range and a slight dip in the lower bass by 3-4 decibels starting from 50 Hz to 20 Hz. Unless you are bass fiend or preferences lie with an artistically warm sound, these are some of the best headphones under $1000. Bear in mind that this assessment was made over years with countless Beyerdynamic, Grado, Sennheiser and even HiFiMAN headphones I have either bought or used for hours each on an individual and head-to-head comparison basis.
I picked up a used pair of these a few months ago and they've quickly become my go to closed cans. They are a little tight and a little heavy, but not enough to bother me and they isolate really well. I'd argue they sound at least as good as the AKG K550. Plus they fold up nice!
I have owned the SRH 840 and I can tell you this: those headphones are not comfortable at all. It gets too hot around ears within 15 minutes. Don't think these headphones offer a vast improvement when it comes to the comfort aspect.
Huh? I wouldn't consider $300 to be a budget headphone by any means, even for audiophiles. The Momentums costs the same, also made any China (like most other headphones, be it a budget headphone or not) and they are much, much better.
Anfieldhence my recommendation of the 840's , the same set you've owned previously.<br />if you don't like pleather, just replace the pads and you get an excellent value for the money.<br /><br />The 940's come with velour pads though, and not pleather like the 840's...<br /><br />Oh, and 300 is not much in reference/monitor standards, but it's not the point - the 840 is better balanced and offers better value for the money.
