If all your doing is music, then an external USB/DAC/headphone amplifier is fine, (HiFiman EF2A tube headphone amplifier).
Gaming and movies are better using a sound card (surround sound), they also do music too.
I'm an Xonar sound card fan (Essence STX) which does everything fairly well, but that's $180.
But would be the best sound card for powering Beyerdynamic DT880 (Premium or Pro) 250-Ohm headphones.
One low cost device is a single tube headphone amplifiers sold on eBay, ships from China, takes 10 days.
Prices start out at $45, better ones start at $75, even better (Indeed G3) go for $120.
You would also need a digital multi-meter (DT830) which start at around $7
to make fine voltage adjustments to these Chinese ampsto bring out their best.
You can always add an external DAC like the Fiio D3 for around $30.
