only got those 2 as an option? i never heard their sound, but i think there are better speakers out there for the same price.
have you tried looking other option from other brand that has a good track record on affordable multimedia speakers?
brands like altec lansing, edifier, thonet-vander, swans.
in that case, my only suggestion is, bring your best portable audio player (an android with mx player apps might do) and some sound files of your liking (preferably in flac format). and do a test hearing audition.
personally i avoid speakers with gaming gimmick since usually their bass is to way boomy and their midrange makes vocals hard to comprehend.
