sE In The Studio

What makes the sE Reflexion Filter® so unique?

Often copied, never equaled.

Since sE invented the Reflexion Filter® in 2006, it has brought studio-quality vocals to over 120,000 rooms all over the world.


Since then, other companies have produced dozens of copies & clones, but sE's original Reflexion Filters have remained the industry standard for portable acoustic treatment due to their patented multi-layer technologies, which don't affect the sound of your favorite microphones like other imitation filters do.

So why can’t you just use a material like cardboard or foam around your mic?

A dense material like cardboard stops room sound, but creates new direct reflections, causing severe acoustic effects.


A softer material like foam helps keep out the room’s high frequency reflections, but doesn’t do anything to stop the lows.

Only sE’s patented multi-layer technologies diffuse and absorb sound across the entire frequency spectrum, so the room reflections are filtered EVENLY - this means that your microphone still sounds like your microphone, even in the crucial midrange frequencies.
