7Hz Timeless II
Approved coverage treats the Timeless II as a real second-generation effort rather than a rebadge: the dual-sided 14.5mm planar brings the punchy, fast bass the original was loved for, while the treble extends further and the stage opens up. The consensus verdict is that it is one of the strongest planar IEMs near $229, with the familiar planar caveats: upper-midrange energy that can turn edgy on bright recordings, and a large disc-shaped shell that not every ear tolerates. Compared with the original Timeless, reviewers hear a more refined, more extended, and slightly more expensive-sounding tuning, at a price that moved up alongside it.
Simgot EA500LM
The EA500LM is a single dynamic driver IEM in an all-metal, mirror-finished shell, sold at about $89 with three pairs of screw-in tuning nozzles. The tuning is described as a balanced U-shape with elevation at both extremes: sub-bass extends deep and lands with punch, slam and chesty impact, and the treble is bright, airy and extended. Reviewers do not agree on what that treble costs. Some report occasional sibilance in the upper treble, female vocals turning a tad strained, a not-smooth and slightly peaky presentation, and fatigue over long sessions for treble-sensitive listeners. Others hear highs that stay clear, liquid and smooth and never turn harsh, piercing or sibilant. Bass definition divides them the same way: one read calls the low end thick, round and often bloomy and names it the weakest part of the set, while others find the sub-bass and midbass clean, defined and free of boominess. The nozzles are a third fault line. One measurement-led take found two of the pairs sounded and measured the same, and another reviewer skipped them entirely as making little difference to the sound profile, yet a third needed the gold pair before the upper mids stopped sounding overly present, harsh and fragile. Build quality, comfort and detail retrieval draw broad praise, while soundstage width is the attribute most often qualified. This is a strong budget dynamic driver whose agreeability depends on treble tolerance and on which nozzle is left installed.
