EAR-POPPING VOLUME THAT GETS THE PARTY STARTED. Stomp XL isn’t just eXtra Large — it’s neXt Level. Sure, it’s packing a bigger driver for cleaner, louder sound, but it also features dual tweeters and Bass Boost for more punch. Stomp XL can handle a house party on its own and it adds the convenience of total portability, water-resistant construction, the ability to link to up to 99 more Skullcandy wireless speakers and an LED light show.
