IEMs for competitive FPS: what to look for

In-ear monitors are popular with competitive players for their isolation and light weight. Fit matters more than any other spec.

Fit and isolation

A good seal gives you isolation and consistent bass. Try several ear tip sizes and materials before judging the sound.

Tuning

Footsteps and utility sounds sit largely in the mids and upper mids. A tuning without exaggerated bass keeps them easy to hear.
