    Tough to comment on the content since I couldn’t hear the speakers at all, even with my phone and cat volume turned all the way up.

  • Dimitri Coukos says:

    Hello, your podcast seems very interesting but the volume levels are very low. Could you increase the gain? I have an iPhone with good quality headphones and even with max volume it can be difficult to hear what you’re saying. Thanks!

  • Sashank says:

    The audio is very low. Couldn’t hear you guys.
