Having a decent set of earphones isn’t really something I’ve ever considered to be important to gaming. When I have played my Switch, 3DS, Vita, or smartphone on the go, I’d just use whatever set I had lying around. Usually, it was the same set I’d wear to the gym, all crusty from my sweat.
Clearly, I should have been taking it a bit more seriously as mobile gaming platforms are home to some dynamic soundtracks and sound effects, something made perfectly clear with the Astro A03 earphones.
