Hey guys, this post is intended for people who are not happy with the stock tuning of the HD800S.
Please check out this software (for both PC and Mac) called the True-Fi from the company Sonarworks. This software is a plug-in, which has EQ correction for many popular headphones, including HD800S. With the EQ applied, the HD800S has a more balanced sound with more bass, and smoother treble, as the software adds more low-end and removes the peaks in the highs. You lose a tiny bit of details in the process, but then it offers a fatigue-free sound.
While using Jriver, I use my own EQ setting on the PMEQ. But then it doesn't allow me to use my EQ outside the app. That's where the advantage of the True-Fi truly lies, because, it is a System-Wide audio plug-in. Meaning, you could listen to Spotify or watch a video on YouTube, and the plug-in will apply EQ correction for your HD800S.
They offer a 10 day trial and, they are currently running a CanJam special until the end of Feb, that you could buy it for $50 with the coupon code: "canjammy". At $50, the software is not cheap. But it might be worth it if you use the HD800S extensively on your PC/Mac. I was initially skeptical about Sonarworks. But reading Tyll's article on the company on Innerfidelity.com was a vote of confidence.
