If you prefer to tweak their sound to your liking, it can be customized in-depth via a graphic EQ or presets in their companion app. However, this may be an issue with our unit and if you have experienced this issue, please let us know in the discussion section below. We could also hear the difference in bass between ears.

This isn't helped by the mismatch between the L/R drivers of our unit, which is most noticeable in the low-bass, high-mid, and low-treble ranges. While their mids are mostly flat and neutral, they have an uneven treble response that results in a lack of detail and clarity.

They're missing a bit of low bass, so some sound effects and bass-heavy music genres may lack thump and rumble. The SteelSeries Arctis 9 have a somewhat imbalanced sound profile out-of-the-box. While we experienced a difference in frequency response between both drivers, it could be due to a quality issue unique to our model. Update : We have clarified the results of the mismatch between the L/R driver.
