The Official Beyerdynamic T1 Impressions and Discussion Thread - Page 559

post #8371 of 8378

Ironically, I already own 2 dt 770 600 ohm drivers (one inside my dt 770 headphones, and one inside a pair of custom one pros), but I still want the tesla 600 ohm (I own those drivers too now, I haven't put it in anything yet).

So I received the 100ohm resistor adaptor and have been using it with the T1 for a few days. There is a noticeable increase in the lower frequencies which gives the headphones a more fuller sound. I've not entirely made my mind up on whether I prefer this or not. Without the resistor the T1 sounds leaner and gives the impression of a cleaner sound. Needs time to adjust I'm guessing.

I can change the ohms of resistance of any pair of drivers then, huh?

post #8374 of 8378

no the resistor adaptor I got effectively increases the output impedance of the amp.

I don't think you can change the drivers' impedance.

 

edit: there was a recent article on innerfidelity about output impedance and its impact on the frequency response of high impedance headphones. Was also trying to mirror the fact that the beyer A1 and A2 amps have 100ohm OI. Can't be certain how close the sound is to them as I don't own them, but was an interesting experiment nevertheless.

 

I was expecting to have to increase the volume, but surprisingly the volume is hardly affected. The volume wheel is almost in the same position as before, around 10 - 10:30.

That silver jack is the 100 ohm resistor adaptor. T1 is connected via sennheiser 6.35 to 3.5 adaptor.

I also bought a 75ohm resistor which has a noticeably less impact to the T1's sound.

Do you guys know of any way to tame the mids of the T1?

I use EQ to "tame" the lower mids (along with the bass and treble) as I find the upper mids too recessed.

when it's a little hot, a little judicious EQing through jriver mc20 works for me

Okay, so I contacted beyerdynamic and found out that the T5p's ear pads are made of real leather and they cost US$205. Whereas, the HS 800's ear pads are also leather, but they only cost US$99 and are far better for noise isolation and have a viscoelastic filling (so they are soft and squishy like a more firm version of honey in a cellophane bag).
