Short answer: the Marshall Willen II, if you are buying new. The Marshall Willen ranks higher than the Sony SRS-XB100 (#14 vs #43 of 63 small speakers) but is discontinued; its replacement, the Marshall Willen II, is rated 4.0/5 at $129.99 and is still sold new.
The Marshall Willen is the better-sounding option. A pocket sized waterproof speaker with exceptionally clear vocals for its size and a solid, durable build. It links with other speakers (Marshall Stack), which the Sony SRS-XB100 cannot. It has an adjustable EQ, which the Sony SRS-XB100 lacks. The tradeoff: Not that deep of bass.
Why pick the Sony SRS-XB100: A pocketable waterproof speaker with a long real world battery, a clip for bags, and stereo pairing. It supports AAC Bluetooth, which the Marshall Willen lacks. Watch for: Not much bass.
Buy the Marshall Willen II, the replacement for the discontinued Marshall Willen; it is rated higher for sound quality than the Sony SRS-XB100.
