Check the listing for details. sE Electronics Reflexion Filter PRO Portable Vocal Booth. Color: Silver/Black, Condition: New. Listed at 199.00 USD. The Easy, Portable Way to Make Recordings Sound Better! What an elegant and simple way to improve the sound of your acoustic space! Not everyone has the budget or the space to work in a perfectly "tuned" and treated acoustic space. But that doesn't mean you can't sound great. Believe it or not, sE Electronics' Reflexion Filter Pro does an amazing job of making your mic sound better because its six different layers diffuse the sound waves around the mic. Better yet, it mounts to any mic stand — you can take this portable acoustic treatment into other rooms or to other locations! The Reflexion Filter Pro from Sweetwater costs a fraction of what a full-room treatment would cost, and it does an outstanding job taming the reflections in the room.
