Hi all,
I just purchased a Beyerdynamic 770 Pro 80 Ohm headphone.
Used for:
- music listening through a NAD amp and Marantz amplifier: all good, loud enough, satisfying experience.
- music production: Windows PC, Ableton Live, Focusrite Scarlett 2i2 (1stgen): not enough volume, unsatisfying experience.
So is the reasoning that a Focusrite Scarlett 2i2 isn't strong enough to drive these for production?
All help welcome! Gracias
PS: yes the PC and source (like Spotify) are all maxed out.

Focusrite recommends at most 200 Ohm cans. Sure it then depends on efficiency of the cans.
Hmmm, the tech specs say Focusrite 2i2 headphone out delivers 7 dBu. That's 1.735 Volts.
Into 80 Ohms that is 22mA or 38mW.
How did I calculate that?

I know that 250mW is enough (in other words: way too much) power and 50mW just suffices. So I can imagine you find it doesn't deliver enough power.
Good luck with the hunt for either a headphone amp or a new interface. Or why not simply connect it to your NAD or Marantz amp?

Nad or Marantz are fine for listening. But sometimes I feel like the best producer in the world and I make underwhelming beats and melodies. That aside, the Focusrite lacks a bit of punch (which is of course responsible). Thanks for the response!

Well, those cheap and USB powered interfaces aren't exactly HighEnd when it comes to the headphone amp and it's power.
And I find Focusrite Scarletts not the hottest things ever with headphones (I have the 18i20 1gen) or overall anyway.
For instance, my Arturia Audio Fuse (1gen) sounds much better and has more power.
So I bought a DROP THX AAA 789 and since then am a very happy camper.
I go from the Focusrite via XLR into the headphone amp and from there to my AKG 712 etc.
Topping makes very good headphone amps too, which are quite affordable.

Fousrite phones outs are bad at large. Even their specific VRM box for mixing on phones did not have a proper phones out for better phones.
With 80 ohm specs, you should get a way with a standard phones out.
Mackie 402 VLZ is a $100 mixer with lots of power on phones out.
Use 70 ohm phones for normal monitoring mecking with synths and such, used at 11 o'clock volume more than enough.
Using 250 ohm phones for mixing though, I use a Pro-Ject Headbox S preamp. $110 or so. This is the 18V version, the newer with usb 5V I have no idea how they sound.

From what I understand, it's mainly about the voltage. USB is only 5V, which doesn't provide enough voltage swing to drive high-impedance headphones.
FWIW, my UMC1820 with an external 12V power supply has no issues driving my 250 Ohms DT880's and 1770's. I rarely use more than 20% volume on the actual volume pot.

Take a single oscillator, producing a drone. Send it to the wave shaper, altering the tone.
This can be a triangle, Sawtooth or a square. Modulate the pulse width, nobody will care

Oh, I had something like that with the exact same setup. Try to unscrew the detachable jack adapter from the headphones just a tiny bit, like a quarter of a rotation at the very most and see if it sounds better. I recon, if you screw on the adapter too tight, the pins inside won't align perfectly with the 3,5 jack, making the sound of the headphones quiet and sometimes a little distorted / mono.
