Until MP3 players and phones getwith truly big sound, we may be stuck with -looking to let loose our inner boombox. Various companies are come up with stopgap solutions that may not look pretty but are at least aimed at delivering beach-boardwalk volume without blowing up.
One of them is the "PodXtreme," which won't win any beauty contests but claims to have a bass that no standard handheld's built-in speakers can come close to achieving, at least not yet, according to OhGizmo. The secret is something that looks like a miniature foot pump but is actually an expandable "resonator" that's supposed to work like a subwoofer in its adult-sized counterparts.
Marketing-speak aside, it won't break the bank at $30. But if you really want to do some serious auditory damage, you can always go with.
