Short answer: the Marshall Willen II. It ranks #11 of 62 small speakers by sound quality (rated 4.0/5) at $129.99 and is still sold new; the Sony SRS-XB13 ranks #45 (rated 2.8/5) and is discontinued, so it is only an option used. The Sony SRS-XB13’s replacement, the Sony SRS-XB100, is rated 2.9/5 at $44.
The Marshall Willen II is the better-sounding, deeper-bass choice. More balanced than the first Marshall Willen, no sharp treble. Its bass reaches about 70Hz before falling 10dB, against 88Hz for the Sony SRS-XB13. It has an adjustable EQ, which the Sony SRS-XB13 lacks. The catch: Not that deep of bass.
The Sony SRS-XB13 is the lighter choice. A removable strap hangs it from a bag or bike. At 0.6 lbs (255 g) it weighs noticeably less than the Marshall Willen II at 0.8 lbs (360 g). It supports AAC Bluetooth, which the Marshall Willen II lacks. The catch: Not much bass, and the sound is muddy.
Buy the Marshall Willen II. It is rated higher for sound quality and still sold new, while the Sony SRS-XB13 is discontinued.
