Short answer: the Xiaomi Mi Portable Mini for features and price, the Sony SRS-XB13 for runtime, though neither ranks well in its class. The Xiaomi adds TWS stereo pairing, a bass boost equalizer, dual drivers with a passive radiator and a mic, and costs $39.50 less, though it shares the Sony’s not much bass and rolls off the treble. The Sony runs around 16 hours and is IP67 rated with a removable strap for hanging on a bag or bike. Both are rated below 3.0/5 among the 54 small speakers, so if sound quality matters, consider the Tribit Stormbox Micro 2 instead, ranked #1 at $59.99.
Buy the Xiaomi Mi Portable Mini if you want one new; the Sony SRS-XB13 is discontinued, so only look for it used.

Sony SRS-XB13: $61.49 Discontinued Amazon eBay
Newer model: the Sony SRS-XB100, ranked higher, rated 2.9/5.
Pros: Sony SRS-XB13 uses 46mm. Its 255 g, claimed 16 hours (Manufacturer specified) battery life, IP67 protection, up to 88dB and mono playback make it a practical option for its intended room or portable use. A removable strap hangs it from a bag or bike. Measured bass extension of 88Hz (-10dB).
Cons: Bass is limited by its 88Hz specification. There is no companion app. No EQ adjustment. Not much bass, and the sound is muddy. Discontinued.
