BEEST FULLSTOP INSULATION (10%off)
I tested BEEST USA Full Stop by boxing up a Bluetooth speaker and measuring the sound before and after with a decibel meter. The readings dropped a lot, and you could hear the difference, so I can say it locks in sound and passed my test. It also cures up with a solid, waterproof exterior and a more compressible interior.
