For any of these decent audiophile headphones you will want and likely need an amp. It’s pretty simple: you plug the amp into a wall, then connect one cable from your PC/laptop to the amp. Then you plug your headphones right into the amp. Your sound and volume will be massively improved and the added bonus is a nice volume knob on the amp. There are definitely cheaper amps than the Topping (which is actually an amp/DAC combo), but it will work for pretty much anything you throw at it.
