Instead of buying a whole new earmuff, you can save money by replacing the foam cushions with the Howard Leight by Honeywell Hygiene Kit for Thunder T3 and T3H Earmuffs. This kit includes one pair of our specially-designed ear cushions and one pair of foam inserts. Together they can extend the lifespan of your earmuff and improve its performance. Replacing the old ear cushions is easy: just pop out the old ones and snap the new ones into place. Replacement is recommended every six months more frequently if your earmuff sees heavy use in the workplace.
