I need your help folks. I may sound a bit stupid asking this but whatever...
Just got my DT 770 pro headphones (250 ohm) and am a bit confused because no matter what I do I cannot get the sound really loud. Am I missing something or what? Granted, I am only using the onboard soundcard from my Maximus VII Hero mainboard but from what I read it's supposed to have a good soundcard. I mean, the sound is really good and all. I just want it to be.... louder. I turned everything to max in both Windows and the Supreme FX manager but I would still like it to be a notch good louder.
Now, I could and would also be willing to buy an additional amplifier but before I do I just wanted to confirm that I didn't miss anything. I'm a bit puzzled because I saw people claiming in other forums that the headphones are loud enough for them without an additional amplifier, which I find very hard to believe giving the sound I am hearing (and yes, I have a good hearing).
Did I miss some settings or is this normal? I never had problems getting loud sound with my old Stereo Headset from Sony - but that one had it's own volume regulator, which the DT 770 pro doesn't seem to have.
Would really appreciate help. Sorry for the (probably dumb) question. I'm an audio noob. :(
Generally, the higher the headphone impedance, the higher the voltage required to play at a specific volume. Sensitivity of the driver is also a factor, but it's mainly impedance.
Low impedance headphones are easy to play at loud volumes, since they require less voltage.
So why aren't all headphones low impedance designs, and why do some studio headphones have different options for impedance?
Well high impedance headphones generally require that you connect them to an amplifier to play at good volume levels - which is going to be readily available in a studio environment.
High impedance headphones avoid picking up noise from the source, and are easy to drive without distortion.
You just throw voltage at them to solve the problem, and you generally don't have to worry about damping factor at all, since 1/8 of 250Ω is 31.25Ω, which is a very high output impedance.
Low impedance headphones have to worry about the output impedance of whatever they're connected to.
They're sensitive to noise (hiss) and require a well-engineered headphone output that has a very low impedance.
They also require a current-based amplifier rather than a voltage-based amplifier to be driven well without distortion. This will make them sound "less refined" than they could, rather than sounding
bad though.
That being said, the 80Ω DT770s are what I'd call moderate impedance, not
low impedance headphones.
If you have, or plan to use a dedicated headphone amplifier, the higher impedance headphones are what I'd recommend.
The low impedance headphones won't need an amplifier for volume, but would potentially benefit from one for audio quality.
Looking over the manual for the
Maximus VII Hero, it appears that you have to install their software and be connected to the front headphone jack to use the "Sonic SenseAmp" feature.
It apparently detects the headphone impedance automatically and changes the headphone amplifier's output accordingly.
