MarcidifYou can use them with a laptop and they'll get loud enough, but they won't sound good. These are good headphones, so they need a good source for you to hear their true sound. As a bare minimum, get a USB DAC/amp like a Cambridge Audio DacMagic XS v2, any of the AudioQuest DragonFly or Apogee Groove variants. If you have a G or V-series LG phone from the G6/V10 and up, you're set. Those have proper audio chipsets.
