Okay, I checked out the Beyerdynamic website and here were the descriptions for each set of cans:
DT 250:
▲ Closed headphone
▲ Good ambient noise attenuation
▲ Lightweight, low profile design
▲ Single-sided, detachable cable
▲ NEW - Limiter (Optional)
▲ Powerful neodymium headphone system for excellent reproduction accuracy
▲ Balanced sound impression
▲ Circumaural ear pads, advanced ear cushion system
▲ Adjustable, soft padded headband
▲ Service-friendly construction due to exchangeablitity of all parts
▲ Single-ear-version: DT 252
and for the DT 48:
▲ Dynamic monitoring headphone for all sound recordings
▲ Meets the standards set by Nagra recorders, DAT and MD portable recorders
▲ High degree of efficiency
▲ Flat accurate frequency response
▲ Good ambient noise attenuation
▲ Rugged construction
▲ Nickel-plated spring steel, adjustable headband
▲ Excellent comfort for long-term wearing
▲ Single-sided cable
It says "powerful neodymium headphone system for excellent reproduction accuracy" for the DT 250 and it says "flat accurate frequency response" for the DT 48. I made a thread a bit ago (http://www.head-fi.org/forum/thread/506000/headphones-flat-fr-low-sibilance-fidelity/45#post_6842422). Someone reccomended the DT 250 for a flat frequency response and sonic fidelity. But, the description doesn't say that on the beyerdynamic website about the DT 250's. Essentially, what I am getting at is... are they similar in the reproduction of sound? I want headphones that are accurate and I am really considering the DT 48s and DT 250s. To be honest, I listen to a lot of metal and industrial but I want sonic fidelity. Anyways, if someone could fill me in on their opinion of the DT 48 vs. the DT 250 I'd really appreciate it.
PS: there is no bass impact apparently with the DT 48? Do producers record albums with the idea that cans that don't have a flat frequency response will be used to listen to the music? If that is the case then the DT 48 and/or DT 250 would not provide me with sonic fidelity. Anyways, that was an issue and debate raised in the thread provided above but I think it is worth discussing in more detail!:) I appreciate your time and thank you very much!:):)














You say it's only emphasized in comparison to the DT48. Is the DT48 not neutral in a way that it is actually bass light? Are the lower end frequencies too light? I am speaking completely objectively here. Taste put aside, why can't headphones just be measured and we have an objective reading as to whether they are completely flat or not. Oh, Head-Fi! You will be the end of me!

I'm just kiddin'. Hmm, of course if the DT 48 is flat I will hear the bass and the full extension that exists in the recording. But, if I have the DT 250 then I will have added bass extension that is added by the headphone itself. Something about that just rubs me the wrong way. It seems almost ridiculous that there are headphones that do this. In an ideal world I would want all headphones to be flat and exactly what was recorded and intended to be heard is being reproduced. No tinkering, nothin'. Just straight up sonic fidelity.
