Well-tuned if technically lacking in comparison. Could use some more power in the bass.

Youtube Video Summary

Timeless 2 shows up with a bigger, round shell (carbon-fiber face, metal rim), a nice hard case, and an oddball-but-cool ribbon cable on MMCX that feels a bit stiff. The real headline is the swappable nozzles: tiny side-vent “pin” nozzles (stock), a “flower” top-vent nozzle, and a large side-vent set. Tip pack is a colorful grab bag (no foams), and care is needed because narrow bores can block those side vents. Power isn’t a problem—this set is very efficient and plays happily from a phone or desktop amps without turning harsh.

Sonically, the three nozzles behave like three different tunings. The stock tiny side-vents are wide, chill, and distant—easy listening with big space. Swap to the “flower” top-vent and everything snaps into focus: detail rockets up, staging comes closer, and transients clean up without tipping into sibilance; bass also tightens and gains punch. The big side-vent option brings more bass weight and a huge stage, trading a bit of hyper-detail for scale and fun. Tip rolling matters: wide-bore silicone (e.g., Dunu SS) or high-seal foams can make it a party in the head, while tight-bore foams can choke the vents and thin the sound.

With the right nozzle/tip combo, Timeless 2 goes from “good planar” to aggressively engaging: thunderous taiko hits, breathing and string texture on acoustic tracks, and club-ready energy on electronic. It feels like the most complete planar IEM here—big soundstage, real bass presence, and crisp clarity that invites louder listening. If pricing sits around the speculated $260–$320 range, this could muscle aside a lot of sets under $500–$600. Verdict: a bold, successful experiment that delivers three flavors of planar goodness, with the “flower” nozzle as the standout for clarity + slam.

Good all-rounder set with solid tech. Good variety with the nozzles that actually changes the sound. Treble is smoother than other planars, and not much "planar timbre".
Youtube Video Summary

7Hz Timeless 2 arrives as a polished successor to the original, delivering a smoother, more refined treble and a presentation that feels less “planar” in timbre. Its headline feature is the interchangeable nozzle system that meaningfully changes the sound—three distinct tunings rather than subtle tweaks—so fit and flavor are easier to dial in. Technicals remain solid for the class (layering, separation, staging), but the emphasis shifts from raw edge to easy, airy listenability; compared to brighter, snappier planars, this one trades a touch of bite for balance and comfort. Pairing with regular Sedna-style tips further smooths the top end without dulling it.

Midrange is handled with a calmer 2 kHz region, so vocals sound less forward and less shouty on energetic tracks. The silver nozzle tames that zone even more, appealing to listeners who prefer flatter upper-mids while adding a sense of openness and clarity. Bass is punchy, quick, and clean with good impact that avoids bleed; it won’t out-slam a strong dynamic-driver set, but the planar low-end here feels tight and versatile, fitting an all-rounder profile. If ultra-etched detail and hyper-tactile treble are the goal, some rivals push further; if the priority is smoothness without boredom, Timeless 2 hits the brief.

As a value play, sub-$100 options still undercut it, yet the combination of refinement + three nozzles makes Timeless 2 competitive at its price. Owners of recent planars may find it a side-grade in sheer technicals, but for anyone starting fresh—or seeking a safer, fuller tuning that scales reasonably—this is a confident recommendation. Use the smoothing tips and select the nozzle that fits the library, and it becomes a comfortable daily driver for most listeners.

Sounds is identical to the Timeless OG. Clean, impactful bass, great detail, fast transients. Upper mids are a bit intense, bright treble, planar timbre.

The 7Hz Timeless II updates its predecessor with a 14.5mm planar magnetic driver featuring a dual-sided silver alloy diaphragm and N52 magnets, offering improved responsiveness and reduced "planar timbre" compared to the original . Its standout feature is the four interchangeable nozzles, allowing tonal adjustments—though the bullet-shaped variants suffer from condensation issues and noticeably reduce treble clarity . Comfort is decent for medium-to-large ears, but the aluminum shells may challenge smaller anatomies, and isolation remains average despite a secure fit .

Tonally, the Timeless II leans neutral with a sub-bass lift, delivering fast, textured lows that avoid bleeding into the mids . Midrange clarity is strong but can edge into harshness with upper-mid-forward tracks, while treble extends well without excessive sibilance . Technically, it excels in imaging precision and soundstage width, though depth and height feel constrained next to hybrids like the Simgot ET142 .
