Short answer: the JBL PartyBox On-the-Go Essential. It ranks #66 of 98 boombox speakers by sound quality, rated 3.0/5, at $279.95. The Monster Bambox ranks #74, rated 2.8/5, at $219, $60.95 cheaper, which does not close the gap in sound quality.
What the JBL PartyBox On-the-Go Essential does well: Includes a wireless microphone plus wired mic and guitar inputs with echo, bass and treble controls for karaoke. The catch: No measurements, so its rating is estimated; it is essentially the JBL Partybox On the Go without app support.
The Monster Bambox is the longer-running, tougher choice. Rated for up to 48 hours from a long life LiFePO4 battery, with IP67 waterproof and dustproof rugged housing, Auracast linking, a 30 watt USB-C charge out, a microphone input, app controlled EQ presets and 256 RGB lights. It is rated for 48 hours of battery against 6 for the JBL PartyBox On-the-Go Essential. It is rated IP67 against IPX4 for the JBL PartyBox On-the-Go Essential. It links with other speakers (Auracast), which the JBL PartyBox On-the-Go Essential cannot. The tradeoff: No measurements or reviews, so its rating is estimated, and the 300 watt figure is peak power (100 watts RMS).
Buy the JBL PartyBox On-the-Go Essential. It is rated higher for sound quality, and saving $60.95 with the Monster Bambox does not make up for the sound-quality gap.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: JBL PartyBox On-the-Go Essential 2.7 to 3.2; Monster Bambox 2.4 to 3.2). Treat this verdict as provisional.

JBL PartyBox On-the-Go Essential: $279.95 Estimated Amazon $279.95 eBay
Pros: Includes a wireless microphone plus wired mic and guitar inputs with echo, bass and treble controls for karaoke. A 100 watt woofer and tweeter layout with Bass Boost, a synced light show, USB playback, aux input, TWS pairing with a second unit and a padded shoulder strap.
Cons: No measurements, so its rating is estimated; it is essentially the JBL Partybox On the Go without app support. Only 6 hours of battery, Bluetooth 4.2, no EQ and splash only IPX4 protection. In a direct comparison the newer PartyBox On-The-Go 2 plays clearly louder and adds app control and a removable battery for about $50 more.
