Short answer: the JBL Partybox Encore Essential. It ranks #8 of 98 boombox speakers by sound quality, rated 4.2/5, at $329.95. The Zealot S95 ranks #35, rated 3.7/5, at $157.41, $172.54 cheaper, a saving that is not big enough to make up the sound-quality gap.
The JBL Partybox Encore Essential is the better-sounding, deeper-bass pick. Its bass reaches about 38Hz before falling 10dB, against 45Hz for the Zealot S95.
The Zealot S95 is the longer-running, tougher option. A good value for the boombox class. It is rated for 12 hours of battery against 6 for the JBL Partybox Encore Essential. It is rated IPX6 against IPX4 for the JBL Partybox Encore Essential. Watch for: A little rolled off up top and not that balanced through the rest of the range.
Buy the JBL Partybox Encore Essential. It is rated higher for sound quality, and the $172.54 saving on the Zealot S95 is not enough to make up the difference.
