Short answer: the Sony SRS-XB12, though neither ranks well in its class. It ranks #41 of 49 small speakers by sound quality, rated 2.5/5, at $79; the Lenovo 700 Ultraportable Bluetooth Speaker ranks #46, rated 2.3/5, and costs $85, so there is not much of a tradeoff to weigh. Both are rated below 3.0/5 among the 49 small speakers, so if sound quality matters, consider the Tribit Stormbox Micro 2 instead, ranked #1 at $49.99.

What the Sony SRS-XB12 does well: Sony SRS-XB12 uses 46mm. The tradeoff: Bass is limited by its 97Hz specification.
What the Lenovo 700 Ultraportable Bluetooth Speaker does well: Very thin profile: about 11mm, similar footprint to a phone. The catch: Huge lack of bass, probably better off with your phone audio.
One note: the Sony SRS-XB12 is discontinued and no longer widely available new.
Buy the Sony SRS-XB12. It is rated higher for sound quality than the Lenovo 700 Ultraportable Bluetooth Speaker and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
