There's a DT48a.0 and DT48.00, apperantly. I think the single 0 might've been a typo though and a different box from different production dates.

woops, I didn't realize you already knew about that one.

I have a turtle beach phone frame handy, now if I can find some 25 ohm drivers....


(I have sent a question message to the ebay seller, asking whether it is indeed a driver, and if so, what impedance it is. Will keep you guys updated)

How's the frequency balance (among other things) compared to something like the ety ER4?

It's a 8ohm driver, and I'm pretty sure it's a driver, since it had a sticker with "system" on it. That doesn't mean you shouldn't get them. That is probably the cheapest you'll find drivers for.

Ah, so here's where all the DT-48 action is these days!

I was under the impression there was only one, and that the A stands for Audiometric

At least two, I think. As far as I know, the one with the two coloured cups was originally made as an anniversary model in 1997 or so. (Or so I seem to vaguely remember. I may be wrong here.)

I can only speak for the dt48 e version on my system ,

Running test tones shows it's flat from 100hz - 15kz with a roll off at each end
Bass pretty much dies at 60hz, and my personal hearing goes south after 16khz so it may extend further I just can't hear it.

The detail level surpasses the ER4s.

Maybe I should fire off an email to beyerdynamic and see if anyone there can give us some answers on the dt48a ?

@drosera

I don't think so...
Most, if not all audiometry headphones have two different colored cups, well my knowledge comes from my like 20 hearing and vision tests, so I still can be wrong.

Hey, kbi, isn't jrosenth part of team DT48?

So both highs and bass are lacking. Then what music does it do well, and what's the magic (if you think they do something good?) Maybe the detail is because a lot of sound is missing?

I wouldn't say "a lot of sound is missing" Just bass under 60hz , and extreme high frequency response of which I can't really hear anyway.
Personally i can live with that and i Listen to a lot of electronica, and rock .

The dt48's main attraction are it's totally uncolored mids and highs (which is extremely rare to find in a headphone), as well extreme amounts of detail.

I'm not sure what the secret sauce is for the extreme detail, but i can't see how not being able to produce very low bass would have any effect ?

I should have been a bit more specific. To my ears the ER4's seem pretty flat. How does that compare to the DT48e? Do they have a similar frequency response?

In a way I actually think neither are lacking. It just very refreshing to finally hear a headphone that doesn't exaggerate both ends of the frequency spectrum. Certainly the bass is some of the finest I've ever heard, for me this is the ideal 'closed headphone bass'. Detailed, focussed and perfectly in proportion to the rest of the frequency range.

The absence of boosted or bloated bass will certainly help with the amount of detail you can get from this 'phone.

Ha, this really is one of the main disadvantages of the DT-48. I don't really think they get more sweaty than any other closed headphone, but because the screen in front of the driver is aluminium and therefore quite cold, all the moisture collects there. Makes it rather conspicuous.

Does anyone know what department at Beyerdynamic to talk to about buying a set of drivers for the DT-48 E?

Also would anyone be willing (if they don't already exist) to take picture of it inside and out with a ruler next to it? How is the driver mounted, what if any stuffing is used, what is the interior space like, etc, etc?

Working on a project for the summer. All I'll say for now is like a tank.

Detailed and focussed bass should be a good thing. But... silence below 60hz (or is your set different?)
