If you've spent any amount of time researching the best gaming headsets, you're bound to have come across differently-sized audio drivers. No matter if it's a pair of cups from Razer, SteelSeries, or Logitech, they'll be listed amongst the rest of the specs, and sometimes, even be plastered across the side of the packaging.

Gaming headset audio drivers can come in sizes from anywhere between 20mm to 50mm, but most modern pairs will switch between 40mm and 50 mm. If you have absolutely zero experience in audio tech, reading these sizes may just sound like audiophile gobbledegook. But the size of your audio driver can give you an idea of what to expect when it comes to sound - 40mm are better equipped to handle higher and mid frequencies, meanwhile 50mm are more suited for lower bass frequency ranges.

It's not an exact science, and there are more important determining factors, from the type of driver (eg, dynamic, or Planar Magnetic) to the quality of the components that make up the speaker to begin with. But if you're stuck choosing between two headsets, one with 40 mm-sized drivers and one with 50mm, I'm here to explain how they differ, and what that means for your future gaming sessions.

Before I get into the real meat of comparing 40mm to 50 mm-sized drivers, it's worthwhile explaining what they are to begin with. Audio drivers are the little speakers found within your headsets, and they're found in everything from the best wireless headsets like the SteelSeries Arctis Nova Pro Wireless, to the plethora of cheap, off-brand pairs of cups clogging up popular online retailers like Amazon and Best Buy. These compact speakers are an integral part of your gaming audio tech, as they convert electrical signals from your device into sound waves, so you can hear all the action from your favorite games - and all the Netflix TV bingeing in between.
