The Matrix® offers a new, patented, no-roll design, which makes insertion easy. The smooth outer skin and reduced diameter provide long-term comfort for the user. It delivers instant protection upon proper insertion - there is no need to let the foam expand. The uniform attenuation profile blocks loud noise while voice frequencies can be heard more naturally. The Matrix® has all this with a NRR rating of 27! Packaged per pair in an individual poly bag. One size fits all.
