Decibullz Custom Molded High-Fidelity Earplugs review

Decibullz takes a different route to fit. Instead of choosing from tip sizes, you heat the Thermofit molds and press them into the bowl of your ear, so the earpiece follows your own shape. A high-fidelity filter sits in the mold, and Decibullz pitches the result at concerts, festivals and nightclubs, saying it keeps music clear while lowering the volume. At $39.99 it costs far less than a custom mold from an audiologist, and Decibullz also sells a Professional High-Fidelity version for more. The product page does not give an attenuation figure for this filter, which makes it hard to compare with the rest of the list, and the brand's own warnings say to test the fit in progressively louder places before relying on it. The molding process also needs care: Decibullz says not to put the mold in your ear while hot and to remove piercings first. It is worth a look mainly if universal tips never seal well for you.
