post #856 of 862

These, BTW are very good headphones. I have most of the major players, but use these a lot. Not the most comfortable, so it forces me to swap out when fatigue sets in.

 

We need a decent source for straight cables, BTW. They must exist in the UK, but the USA is SOL, looks like. 

 

DT250/250

Hey, i noticed strange effect, when i turn my head right, and only right bass gets pretty good boost... And i can not understand the nature of it is head turn does not seem to change clamping force somehow. Any ideas?

I have an idea. In fact:
​I just took mine apart for the same reason - bass was quieter in the left cup. I don't like that PCB - it can't be good acoustically. I've already modded mine a while ago, there's some acoustic foam under that silly PCB:

Also the brown wire just broke off on its own while I was fiddling with the cup..it was holding on a hair..no wonder bass was low


​Being the purist that I am I decided to make things right. Ripped out the stupid PCB, grinded out those nasty bumps that are only utilised in the mic version. Beyer is using the same mold for all of the variants. The single bump inside of the left cup remains - couldn't be bothered this time...
 Glued the socket in, made sure there's a nice seal. It wasn't sealed properly previously and this could have caused the bass drop compared to the right cup which doesn't have this hole... ABS loves that super glue

 

Put some foam, soldered the wires, and also glued the white fluffy ring as it easilly falls out inside the cup.

 

So the question now is, did all of this resolve the issue, right??
​Well it's hard to be objective... It sounds better to me - as always after performing these kind of things to any headphone.
​Sounds somewhat more pure, as is the signal path after this mod. Also the right cup is sealed properly now...bass sounds centered

​Anyways this is one of my favourite headphones - sounds so nice.

Is there a real difference between the DT250/250 and the DT250/80?
Should I get it even if I already own (from Beyer) the DT150/250 and the DT990/250?

Don't. Try some other brand house sound for a change.

The DT250 don't sound quite like the other Beyerdynamics; The DT880 and DT990 have more intense treble peaks. The DT250 has a similar peak, but it isn't as spiky. 

 

Also, as far as the bass imbalance goes, Putting some dense foam between the plug and the left driver housing (basically, poke the pins through some foam and sandwich it there) seems to help sealing a bit and balance the bass a bit better. I think the holes where the pins go in make the left earcup less sealed than the right one, which contributes to bass imbalance.

...and make sure the plug is securely fitted (ideally using the screw).
