Short answer: the Monster Bluetooth Speaker. It ranks #31 of 47 small speakers by sound quality at $19.99; the Sony SRS-XB100 ranks #33 and costs $63, so there is not much of a tradeoff to weigh.
What the Sony SRS-XB100 offers: Long real-world battery life (~17 hours in testing). IP67 rated and pocketable at 267g, with a clip for bags/gear. Can stereo-pair two units. Watch for: Not much bass. Seems pretty much the same as the XB13, maybe a teeny bit deeper bass and a little less muddy.
What the Monster Bluetooth Speaker offers: A very light, IPX7-rated mini speaker with USB-C charging, aux and microSD playback, speakerphone support and TWS pairing. It is a convenient rugged travel speaker when water resistance and small size matter more than bass. Watch for: Its tiny 36mm driver has very limited bass (about 95Hz at -10dB), elevated mids and rolled-off highs. It cannot deliver the scale, detail or battery endurance of stronger small-speaker rivals, and no app or EQ is available to improve the tuning.
Buy the Monster Bluetooth Speaker. It ranks higher for sound quality than the Sony SRS-XB100 and costs less, so the other one has nothing left to offer.
If battery life is a priority, the Sony SRS-XB100 is rated for 16 hours versus 6.5 hours for the Monster Bluetooth Speaker.
