Thieaudio Hype 10 VS 64 Audio U4S

Youtube Video Summary

Build & comfort hit the modern Thieaudio groove: a compact shell with a gentle wing, secure nozzle lip that plays nice with most tips, and a faceplate that’s tasteful if not flashy. The stock EST cable feels soft and skin-like with tidy ear hooks, a steady chin slider, and a clean Y-split—nothing fussy, everything practical. On-ear fit is extremely comfortable, light, and stable over long sessions.

Tonally, Hype 10 brings impactful—but controlled—bass, pristine mids/treble, and a spacious stage with convincing imaging. It reads neutral with a hint of fun: satisfying sub-bass lift, healthy upper-mids, and air/extension that adds space without splash. Note weight and slam aren’t “insane,” but resolution is high and the overall presentation is natural, clean, and engaging. It’s also one of those rare sets that doesn’t beg for EQ.

Against the lineup and peers: Hype 2 feels flat and unexceptional by comparison; Hype 4 is very close, but Hype 10 fixes the upper-air/treble shortfall and steps up stage and resolution. Versus Monarch Mk I, Hype 10’s extra bass avoids leanness; against Oracle MK3, it avoids that 4–6 kHz “flat energy” rise and sounds more natural up top. Dunu’s Mirai charms but runs leaner with a sharper edge; Jupiter can out-punch and extend, yet the price undercuts its appeal; Diva has special upper mids but the dip-switch fiddle and pricing dull the value. Net: under $1,000 (open-box deals around $800 sweeten the pot), Hype 10 is a standout recommendation—and while Hype 4 gets you ~99% of the flavor if its treble suits you, Hype 10 is the more complete, everyday-ready choice.

$900 tribrid with a naming twist: despite the “10,” it’s a 12-driver stack—2x dynamic for the lows and 10x BA for the rest—tuned to feel like a single DD done right. It’s easy to drive yet scales with better amps, delivering a warm, cohesive cloud of sound with a shockingly natural low end from the dual dynamics and clean, clarified treble from the BAs. The tonality straddles the line between fun and audiophile: throw on bangers and it hits; cue up quiet, moody scores and it gets soft, spacious, and atmospheric without smearing detail. Compared to a reference single-DD like Softears Twilight, this set brings better bass authority and brighter treble definition, giving up a tick of soundstage in exchange for a more enveloping, “everything-just-blends” presentation that feels more cohesive than a 2+10 should.

Build and pack-ins are the buzzkill: the shells are huge, the finish can look plainer than promo photos, and the accessories are sparse (basic case, tips, adapters, standard cable). Tip rolling matters—silicone (e.g., Dunu SS) keeps the bass tight and the vibe relaxed; foams can blunt the magic. Despite the light bundle, the tuning is a no-brainer recommendation at this tier: flagship-level dynamics with zero obvious deal-breakers, equally at home with industrial grit and orchestral whispers. Call it a confident 9/10: fewer trinkets in the box, but the sound is the show—and it’s the real hype.

Youtube Video Summary

Thieaudio Hype 10 comes across as a competent all-rounder with a lush, boosted bass shelf, but feedback repeatedly notes a touch of boom and occasional treble peaks that undermine cohesion. Staging and detail feel decent yet unremarkable, and several listeners point to cleaner contrast and dynamics on alternatives like the Helios. While one participant enjoyed the “boom-boom” soundstage and put Hype 10 near the top, most impressions describe the bass as slightly bleedy into the mids and the overall presentation as less resolving than expected at its price.

Against its siblings, the Hype 4 frequently wins praise for a more natural midrange, better balance, and a smoother, more versatile listen; multiple listeners preferred it over Hype 10. Versus the step-up Monarch Mk3 (only ~$100 more), the consensus favors the Monarch for being cleaner, more refined, and more detailed. Non-audiophile participants often struggled to distinguish the lineup, but seasoned ears consistently grouped Hype 10 as a decent generalist that doesn’t feel particularly special next to Hype 4 and Monarch Mk3.

Takeaway: Hype 10 offers familiar, bass-forward isobaric flavor with broadly agreeable tonality, yet value perception is mixed. For most listeners, Hype 4 reads as the smarter buy, and if budget stretches, Monarch Mk3 is widely recommended over Hype 10 for its more resolving and cohesive sound.

Build & package: Both arrive with the same tips, case, and box, but the Hype 10 adds an interchangeable 3.5/2.5/4.4 mm cable. The shells differ in size—Hype 4 is smaller—while the Hype 10’s faceplate is a standout, galaxy-like design. Driver & price: Hype 4 runs 2DD + 4BA at $399; Hype 10 upgrades to 2DD + 10BA at $899, featuring Sonion bass/mids and Knowles ultra-tweeters, plus dual 10 mm isobaric DDs.

Sound & use-case: Versus Hype 4, the Hype 10 brings tighter, punchier bass with more texture and quicker attack, cleaner mids with a slightly more natural timbre, and a treble that’s crisp, airy, and more analytical. It offers better separation, layering, and a slightly larger stage, making instruments, vocals, and even orchestral passages easier to parse—excellent for music and single-player titles with cinematic scores. For competitive gaming, however, the Hype 10’s elevated presence region turns gunshots/explosions spicy and can crowd out footsteps, while the Hype 4 stays smoother up top and keeps positional cues clearer with comparable imaging. On the Wall Hack Certified list: Hype 4 = B+, Hype 10 = B. Net: both are fantastic, but at half the price and with stronger FPS performance, the Hype 4 remains the easier recommendation and current daily driver.

Youtube Video Summary

The 64 Audio U4s hits a compelling sweet spot: a 1DD+3BA hybrid around $1,100 that echoes the lush, bass-tilted character of the Nio while fixing key drawbacks. Packaging and accessories feel improved, with multiple tip options and the included M12 APEX module; APEX not only tailors bass but also relieves pressure for long sessions. Fit follows 64 Audio’s comfortable triangular shell; the vented DD asks for a slightly shallower insert than the all-BA models. Sonically, expect a sub-bass-oriented shelf and a treble profile that’s more lively and “zingy” than the Nio, with extra energy around the upper treble. The big caveat is 64 Audio’s muted 2–4 kHz region, which can set soprano vocals a step back on the stage.

Against the brand’s full-BA staples (think U12t/U6t), the U4s trades some pinpoint imaging and coherency for unmistakable DD slam and tactile “air pushing.” Extension at both ends is excellent, with upper-treble energy that makes micro-detail and reverb trails pop. It’s not the clean, conventional neutrality of something like a Monarch-style tuning; rather, it’s a deliberate, colored signature that delivers fun plus technical chops. Crucially, it fills a missing niche at its price and, in many respects, outperforms the pricier Nio, making the U4s a standout recommendation for listeners who want bass authority, sparkle, and engaging dynamics without going all-in on the flagship tier.
