Short answer: the Xiaomi Sound Pocket for price and features, the Sony SRS-XB13 for battery, though neither ranks well in its class. The Xiaomi brings 5W output, TWS stereo pairing, a mic and USB-C in a 0.4 lbs (200 g) body and costs $38.87 less, but its vocals turn harsh above ~80% volume, it walks on hard surfaces when upright, and it charges in 3 hours. The Sony runs around 16 hours but sounds muddy with not much bass. Both are rated below 3.0/5 among the 50 small speakers; for better sound, the Tribit Stormbox Micro 2 ranks #1 at $59.99.
What the Xiaomi Sound Pocket offers: 5W output, IP67 waterproof, 10-hour battery life, compact 0.4 lbs (200 g) ultra-portable design, Bluetooth 5.4 with TWS stereo pairing, built-in microphone, USB-C charging, 3.6-inch form factor. The catch: Bass light, vocals harsh above ~80% volume, vibrates/walks on hard surfaces at higher volume when upright, slow 3-hour charge.
Buy the Xiaomi Sound Pocket, since the Sony SRS-XB13 is discontinued and only worth hunting down 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.

Xiaomi Sound Pocket: $22.62 Amazon AliExpress eBay
Pros: A genuinely pocketable 200g speaker with IP67 protection, USB-C charging, speakerphone capability and TWS pairing. Independent listening finds it surprisingly loud and clear for hotel rooms, patios and travel, with acceptable sound at moderate volume.
Cons: Its 5W driver has little real bass, and vocals can become harsh as volume rises beyond roughly 80%. When upright on a hard surface it can vibrate or walk around, and the claimed 10-hour battery life applies only at modest volume; full recharging is slow at around three hours.
