Influencer Opinion: Zeos Reviews

  • "I am half-disappointed and half-elated."
  • "The two major benefits of the [BAL over the PLUS]...sound quality is better...and it's got Bluetooth built-in. No more add-on module to the back. That's the two major improvements, and that's it."
  • "[I hate that] they took away the...next track/last track/play/pause [button]."



  • "1W per channel...that's enough for Argons."
  • "This thing is spectacular for powering headphones."
  • "I swear, you could use this on your desk as a desktop amp....this is enough amp and DAC for a full-fledge audiophile desktop setup."
