    $249 feels very reasonable for that considering it includes a DAC.

    Will have to read your other reviews on the brand now.

    Do you guys ever sleep? That’s like the 20th article since Friday.

      I actually purchased a pair of the Holocene and still use them. Excellent IEMs. Need a warmer sounding Dongle. The Axion could be a really good value if the IEMs are good.
