Bought this for my studio setup in my new apartment to lessen reflections. With a wall and two large windows behind my setup, not much can be mounted here, the curtains seemed like an excellent and discrete way to treat that area, and they certainly were. In combination with a few basstraps, this is whats hanging behind my desk. They also help to soften outside noise and block out all sunlight, so they help me focus on just the music as Im working.
If you are expecting any kind of mid or low dampening from these curtains, youre out of luck, but for high and midrange frequencies, these work well. They dampen reflections down to 250 Hz very effectively and visually they look like your average curtain, so if you need to soften a large wall with windows or glass doors on them, look no further.
One big pro for this product is also how much material you are getting for your money. There are thicker curtains out there, but they are significantly smaller and higher priced. With these, you get a very solid amount of dampening on a large area for a very decent price point.
