At eight inches wide, the SRS-X5 isn't a speaker you'll be putting in your bag to take on a picnic or to the beach, but CNET says it "can be easily moved from room to room." You wouldn't want it near water anyway, as PC World Australia notes it's let down by "a lack of waterproofing." But otherwise, PC World Australia says it's "well thought out" with "a touch of prestige."
That prestige extends to the sound the X5 puts out, with CNET "impressed by the amount of bass it delivers for its small size and its clean, relatively natural sound." PC World Australia tried various albums out on it, finding "trance tracks are particularly ripe for a speaker of its calibre" but it "struggled with" rock, partly due to "the SRS-X5â€™s limited dimension."
The SRS-X5 offers acceptable sound in a handsome package, but for the price speakers like the Jambox and the Braven 850 have a lot more to offer.
