These sit in different size classes, so this is not a straight ranking comparison. The Monster Bluetooth Speaker ranks #31 of 47 small speakers by sound quality at $19.99; the Soundcore 2 ranks #86 of 144 medium speakers by sound quality at $29.99.
The case for the Monster Bluetooth Speaker: A very light, IPX7-rated mini speaker with USB-C charging, aux and microSD playback, speakerphone support and TWS pairing. The catch: Its tiny 36mm driver has very limited bass (about 95Hz at -10dB), elevated mids and rolled-off highs.
Why pick the Soundcore 2: Soundcore 2 uses 2x 38mm fullrange. Watch for: Its 70Hz - 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
Buy the Monster Bluetooth Speaker at $19.99 if you want a small speaker. Buy the Soundcore 2 at $29.99 if you want a medium speaker instead.
Battery life favors the Soundcore 2: rated for 24 hours against 6.5 hours for the Monster Bluetooth Speaker.

The Two Speakers In Full
Monster Bluetooth Speaker: $19.99 Amazon eBay
Pros: 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. Measured bass extension of 95Hz (-10dB).
Cons: 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.
