Short answer: the JBL PartyBox On-The-Go 2 Plus. It ranks #5 of 113 boombox speakers by sound quality, rated 4.4/5, at $349.95. The EcoXGear Defender ranks #85, rated 2.5/5, at $299.99, $49.96 cheaper, a saving that is not big enough to make up the sound-quality gap.
The JBL PartyBox On-The-Go 2 Plus is the better-sounding option. A well balanced karaoke party speaker with clean bass, clear vocals, on-board vocal removal, an included wireless mic and a removable battery. It links with other speakers (Auracast), which the EcoXGear Defender cannot. The tradeoff: The bass has less kick and physical impact than the JBL Partybox Encore 2 or JBL Partybox Club 120, and the JBL Partybox Club 120 gets noticeably louder.
The EcoXGear Defender is the longer-running, lighter pick. A rugged, floating waterproof speaker that gets very loud for its size, with a flashlight, bottle opener and power bank. It is rated for 25 hours of battery against 15 for the JBL PartyBox On-The-Go 2 Plus. At 10 lbs (4.54 kg) it weighs noticeably less than the JBL PartyBox On-The-Go 2 Plus at 14.2 lbs (6.45 kg). It is rated IP67 against IPX4 for the JBL PartyBox On-The-Go 2 Plus. The tradeoff: Its single front-facing driver layout has narrow dispersion: clarity and detail drop noticeably when you move off-axis, and the soundstage is limited.
Buy the JBL PartyBox On-The-Go 2 Plus. It is rated higher for sound quality, and the $49.96 saving on the EcoXGear Defender is not enough to make up the difference.
