As someone who just records vocals, I need my recordings to sound as dry as possible and the acoustic panels did just that. Do note that acoustic panels are meant to reduce echo in your recording environment not soundproof. I went ahead and made a second purchase. TIP: If you don't mind, I'd use thumb tacks instead of adhesive tape as the tape can ruin the foam when removing it. It won't do much damage but it'll take a sliver of foam off if removed.
