graphenediscoverer4 the Belkin Rockstar+ is probably the absolute best small DAC/amp you can get for cheap. I've A/B/X tested about 6 lower quality (<$100) ones, and this is the best by far! I used a 7hZ Timeless and Campfire Andromeda for testing, and compared them to an iFi Gryphon and an iFi Gold Bar (WAY better, but that's to be expected, they were both $800+ CAD...)
Differences were much more apparent on the Andromeda, but could certainly hear it on the Timeless as well! Earman Sparrow is you vest bet for a cheaper than what I gave, but better than a low-fi solution like the Samsung, Belkin or Spoke adapters. Those really suck in comparison.
Look here to match your DAC/amp with your load (headphones)

Go wired all the way, it's the smart play! The DAC/amp us very important as you'll see by measurements!
