Short answer: the Ultimate Ears Miniroll. It ranks #12 of 62 small speakers by sound quality (rated 3.9/5) at $50.99 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 Ultimate Ears Miniroll is the better-sounding pick. Good clarity and detail in the mids and highs, with a warmer balance than most speakers its size. It links with other speakers (PartyUp/Auracast, Miniroll-only), which the Sony SRS-XB13 cannot. The tradeoff: Bass does not reach as deep as the best-rated speakers.
The Sony SRS-XB13 is the longer-running pick. A removable strap hangs it from a bag or bike. It is rated for 16 hours of battery against 12 for the Ultimate Ears Miniroll. It supports AAC Bluetooth, which the Ultimate Ears Miniroll lacks. Watch for: Not much bass, and the sound is muddy.
Buy the Ultimate Ears Miniroll. It is rated higher for sound quality; the Sony SRS-XB13 is no longer sold new.
