Vicoustic Vixagon Mini VMT

Wasn't sure the hexagonal shape would actually do much for echo, but after covering one wall in my home office the room finally sounds normal on calls. The felt surface is thicker than it looks in photos and the solid color blends right in instead of screaming "studio foam.

I stuck a few of these on the wall behind my desk and the echo dropped significantly—much quieter for calls. The matte black finish looks clean and doesn't draw attention.

The hexagonal shape makes them way easier to fit around my bookshelf corners than the square panels I had before. Sound in my home office is noticeably less echoey now, and the solid colors blend right in with the wall.
