Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Xtreme 4 ranks #44 of 105 large speakers by sound quality at $309.95; the Soundcore Boom 2 Pro ranks #38 of 98 boombox speakers by sound quality at $139.99.
The JBL Xtreme 4 is the lighter pick. A rugged 4.6 lbs (2.1 kg) portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. At 4.6 lbs (2.1 kg) it weighs much less than the Soundcore Boom 2 Pro at 8.4 lbs (3.8 kg). The tradeoff: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume.
Why pick the Soundcore Boom 2 Pro: A tougher version of the Soundcore Boom 2 Plus with IP68 dust and water protection instead of IPX7, a metal front grille, and a body that floats. It supports AAC Bluetooth, which the JBL Xtreme 4 lacks. It keeps a wired aux input, which the JBL Xtreme 4 lacks. The tradeoff: No side-by-side sound comparisons yet, so its rating is estimated from the Soundcore Boom 2 Plus, which shares its drivers and amplifier.
Buy the JBL Xtreme 4 ($309.95) for a large speaker; the Soundcore Boom 2 Pro ($139.99) suits a boombox speaker instead.
Worth knowing: the Soundcore Boom 2 Pro has not been measured yet. Its rating is estimated from related models, with a likely range of 3.4 to 3.8, so treat this verdict as provisional.

Newer model: the JBL Xtreme 5, ranked higher, rated 4.6/5, released Apr 2026. It adds USB audio input, AAC and LC3, but drops the built-in mic. Water resistance goes from IP67 to IP68.
Older models: the JBL Xtreme 3 (ranked higher, rated 4.3/5), the JBL Xtreme 2 (ranked lower, rated 3.4/5) and the JBL Xtreme (ranked lower, rated 3.2/5). See every JBL Xtreme generation.
Pros: A rugged 2.1kg portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. Independent reviews find the midrange detailed and the sound clear, punchy and refined for outdoor use; it also reaches a strong 106dB maximum level and has excellent real-world battery life.
Cons: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume. The front-facing layout has only modest off-axis consistency, Bluetooth latency is high for video, and the default balance benefits from EQ adjustment. There is no aux input, so wired sources are not supported. Out of the box it leans bass-boosted, with a dip between the upper bass and midrange that EQ cannot fix, and it pushes the upper mids and treble at high volume. It is also expensive.

Soundcore Boom 2 Pro: $139.99 Estimated Woot $139.99 Lowest Walmart $197.00 Best Buy $249.99 eBay
Pros: A tougher version of the Soundcore Boom 2 Plus with IP68 dust and water protection instead of IPX7, a metal front grille, and a body that floats. Inside it is the same 140W design with two woofers and two tweeters for real stereo, plenty of bass with BassUp, a 9 band app EQ, aux input, a detachable shoulder strap, a 10W USB-C power bank and PartyCast for linking more speakers.
Cons: No side-by-side sound comparisons yet, so its rating is estimated from the Soundcore Boom 2 Plus, which shares its drivers and amplifier. That means the same warm stock tuning with upper bass boost and a dip from the upper mids into the treble that dulls vocals, and owners say it needs EQ. Reviewers found it loses fullness and gets a bit fatiguing at its very highest volume.
