These sit in different size classes, so this is not a straight ranking comparison. The Sony ULT Tower 7 ranks #1 of 53 party speakers by sound quality at $648; the EcoXGear Defender ranks #85 of 113 boombox speakers by sound quality at $299.99.
Why pick the Sony ULT Tower 7: A big, loud party speaker on wheels with punchy bass, a 30 hour battery, 360 degree sound and inputs for mics and instruments. It supports LDAC Bluetooth, which the EcoXGear Defender lacks. It links with other speakers (Auracast), which the EcoXGear Defender cannot. It plays in stereo from a single unit, unlike the EcoXGear Defender. Watch for: The reviewer notes that Auracast pairing is not backward-compatible with Sony’s older Party Connect speakers, and the hard-plastic corners lack protective rubber bumpers.
The EcoXGear Defender is the lighter, tougher option. A rugged, floating waterproof speaker that gets very loud for its size, with a flashlight, bottle opener and power bank. At 10 lbs (4.54 kg) it weighs much less than the Sony ULT Tower 7 at 50.3 lbs (22.8 kg). It is rated IP67 against IPX4 for the Sony ULT Tower 7. The catch: 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 Sony ULT Tower 7 at $648 for a party speaker, or the EcoXGear Defender at $299.99 for a boombox speaker instead.
