What headphone impedance is suitable for Steinberg ur242?

Question

Sound cards

Hey!
Unfortunately I don't understand the issue at all. You need to buy headphones to mix the sound under the Steinberg ur242 card. Of course, I look in the direction of the Beyerdynamic dt 990 pro 250 ohm, but I don’t know if they are suitable in terms of resistance?
Of course, the priority is the linearity of the sound.
Here are the characteristics of the card's headphone output: "maximum power: 2 × 15 mW into a 40-ohm load; power consumption: 5 W;"

Answer 1

250 ohm normally work only with a good amplifier.
If you really liked the DT-990 so much, then there is a 32 ohm version of these headphones. Those are suitable.

Answer 2

Amplifier only.
