How does it work?

When you put a microphone in front of you, it doesn't just hear you - it hears the room around you. 

Even if it's a cardioid mic and is listening mostly to just you, it's still picking up reflections from your voice or instrument that are bouncing off the walls and coming back to the mic. The goal of acoustic treatment is to minimize the pickup of such reflections so your primary sound source comes through as pure as possible.

So why not just put some cardboard or foam behind the mic?

Some materials are good at absorbing or reflecting particular frequencies - for example, foam absorbs highs really well, but does nothing for lows.

sE's patented multi-layer technologies absorb frequencies evenly across the whole frequency spectrum.

This is what makes the Reflexion Filter™ unique, and makes it the choice of the biggest recording artists in the world - whether they're working in untreated rooms, or working in a professionally-designed studio and just need a little more isolation.

Where should I use it?

We did a quick search, and came across hundreds of ways our filters are being used. Isolation between a guitar and a vocal, the ultimate portable setup, additional treatment in a professionally-designed room, a pop-up bedroom studio - these are just a few images from users around the world.

When you need studio-grade sound without a studio, you need a Reflexion Filter®.
