Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Monster Bluetooth Speaker ranks #39 of 62 small speakers by sound quality at $19.99; the Xdobo X8 ranks #160 of 179 medium speakers by sound quality at $35.
The Monster Bluetooth Speaker is the lighter, tougher option. A very cheap, light waterproof travel speaker with USB-C charging, aux and microSD playback, and stereo pairing. At 0.4 lbs (185 g) it weighs much less than the Xdobo X8 at 1.9 lbs (860 g). It is rated IPX7 against IPX5 for the Xdobo X8. Watch for: Its tiny 36mm driver has very limited bass (about 95Hz at -10dB), elevated mids and rolled-off highs.
The Xdobo X8 is the deeper-bass, longer-running option. A cheap splash resistant speaker that plays loud for background music outdoors, with aux and microSD playback. Its bass reaches about 65Hz before falling 10dB, against 95Hz for the Monster Bluetooth Speaker. It is rated for 15 hours of battery against 6.5 for the Monster Bluetooth Speaker. It has an adjustable EQ, which the Monster Bluetooth Speaker lacks. The tradeoff: The single full-range driver is the limitation.
One note: the Xdobo X8 is discontinued and no longer widely available new.
Buy the Monster Bluetooth Speaker at $19.99 for a small speaker, or the Xdobo X8 at $35 for a medium speaker instead.
