The Live Pro 2 sit at the very top of JBL's true-wireless range; the WF-1000XM4 are the earbuds with which Sony set out to reclaim the class benchmark. Both offer active noise cancelling, app-based fine-tuning and wireless-charging cases, yet the published tests of the two reach strikingly different verdicts. This comparison draws on those complete tests of both products; Truthful Reviews has not bench-tested either pair itself.
The JBL takes the comfort prize with ease. Its semi in-ear design seals the entrance of the ear canal rather than plunging into it, each bud weighs a feathery 4.8 g, and with three silicone tip sizes fitted the earbuds can genuinely be forgotten in the ear. The build is less flattering: the mirrored touch surface on each stem collects fingerprints, the shell plastic is of debatable quality with visible assembly marks, and only the small, well-finished case — USB-C, wireless charging, three battery LEDs, but a hinge that complicates one-handed use — feels a grade above. An IPX5 rating covers splashes, though during intense exercise the buds tend to slide out as sweat builds.
The Sony is the opposite trade. The near-spherical XM4 buds fill the whole concha, protrude visibly and leave little room for adjustment: larger than average, they simply will not suit smaller ears, and one test noted mild discomfort at the conch and canal entrance after two to three hours. But the polyurethane foam tips isolate better than silicone, a quarter-turn locks the fit, the assembly and copper-accented mic tube look unmistakably premium, and the case is a claimed 40% smaller than its predecessor's — USB-C and Qi charging included, IPX4 on the buds. They shift slightly with jaw movement, and running with them is best avoided; neither pair, in truth, is a sports specialist.
Both makers impose the same irritating tactile compromise: commands are grouped into profiles, so you must sacrifice volume control, playback control or listening-mode switching — you cannot keep all three. From there the experiences diverge. The JBL offers Bluetooth 5.2 with SBC and AAC, Google Fast Pair, wear detection with auto-pause (albeit around 2 s slow), voice-activated Alexa or Google Assistant, and — its ace — multipoint pairing to two devices from day one. The JBL Headphones app brings an equaliser and adjustable noise cancelling, but repeatedly refused to connect during testing, notably on iOS.
Sony's Headphones app is the most complete of the genre: adaptive noise-cancelling control that follows your activity or location, a twenty-level ambient mode, a five-band equaliser with presets, a tip-fit checker, and the DSEE Extreme upscaler — which neither published test could distinguish in blind listening. A speak-to-chat mode pauses music when you talk, though it over-triggers if you merely hum along. Multipoint was missing at launch and arrived later through a firmware update. The XM4 add Swift Pair for Windows, independent left/right buds with mono use, and the headline LDAC codec at up to 990 kb/s — a first at this level — though the default connection mode prioritises stability and must be switched in the app, and LDAC can drop out with the phone in a pocket or in congested areas.
Measured latency on the JBL is a poor 322 ms over standard Bluetooth, but its dedicated Video mode drops that to around 132 ms — comfortable for films and nearly good enough for games, at the cost of brief sound cut-outs roughly every ten minutes in crowded radio environments. The Sony tests recorded no equivalent low-latency mode and no aptX. For watching video on a phone, the JBL carries the more useful tool.
The JBL kept its promise precisely: 10 hours measured without noise cancelling, easing to about 8 hours with it engaged. The Sony's numbers depend heavily on settings, and the published measurements differ accordingly: one recorded 9 h 15 with noise cancelling on the AAC codec and a remarkable 13 h 45 without, while the other reached 5 h 47 using LDAC, noise cancelling and a high listening volume — LDAC alone costs roughly 45% of the endurance. The XM4 case adds further charges for a day-long total, a 20-30 minute top-up restores half or more, and both cases charge wirelessly.
Six microphones with a sidetone function let the JBL capture an intelligible voice in calm surroundings, though the limited bandwidth makes the speaker sound distant, and beside a busy junction comprehension becomes hard work. The Sony pairs its mics with bone-conduction voice pick-up, and here the published tests part company: one judged calls a clear step up from the previous generation and among the better performers of the class, while the other found the voice slightly recessed and suffered frustrating microphone micro-cutouts every 5 to 20 seconds. The honest reading: neither pair is a calling champion, and the XM4's real-world call quality may vary.
The JBL's cancellation is honourable: engine drone, ventilation and train rumble are properly reduced, but mids and highs — conversations, keyboard clatter — remain audible, wind is handled poorly, and sudden pressure changes register. The Sony operates in another league. Its attenuation is unusually even across the spectrum, it is arguably the best of any earbud at suppressing sudden sounds like key strikes, and one test found the silence so complete that nearby voices became barely discernible — with a dedicated wind-reduction mode on top. Sony's transparency mode is useful and strong, if a touch less natural than the very best rivals. On silence, the XM4 win outright.
Here the gap is widest. The Live Pro 2's signature is heavily V-shaped: thunderous, imprecise bass that spills into the lower mids, an aggressive push around the 4 kHz presence zone that quickly fatigues, and shy extreme treble that flattens the stage's depth. The mids between those excesses render timbres and voices faithfully, and the equaliser can partially tame the rest — but only partially. The XM4 deliver a powerful, rounded balance with controlled, dynamic bass, voices free of sibilance, slightly recessed treble lifted by a 10 kHz sparkle that only occasionally turns artificial on cymbals, and a soundstage whose width and depth rank among the best of any true-wireless earbud, with genuine dynamics on demanding classical material. One test placed them within touching distance of the most technically accomplished rivals in the category.
Choose the JBL Live Pro 2 if all-day featherweight comfort, multipoint from day one, the low-latency Video mode and dependable 8-10 hour endurance matter more to you than fidelity — and plan to spend time in the equaliser. Choose the Sony WF-1000XM4 if sound and silence come first: class-leading noise cancelling, genuinely excellent audio, LDAC and the deepest companion app of the genre, accepting bulky buds that smaller ears may reject and call microphones that divided the published tests. For most listeners buying earbuds to listen to music, the tests point one way: the Sony.
