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.
Moondrop Aria 2
The Aria 2 is a single 10mm dynamic driver IEM whose most concrete gains over the 2021 Aria are physical: a milled zinc alloy shell, a replaceable brass nozzle, a modular cable terminating in both 3.5mm and 4.4mm, and a leather-style zip case. It is easy to drive, carrying manufacturer figures of 122 dB/Vrms and 33 ohms alongside an impedance curve reported as effectively flat, so source pairing is not a concern. Tuning is broadly balanced with a mild U shape. Bench measurement shows a dip near 500 Hz, a consistent lift of about 3 dB from 1 kHz to 3 kHz, and extra energy between 3.5 kHz and 6.5 kHz. That upper-midrange lift is the most complained-about trait, drawing repeated descriptions of shoutiness. Coverage splits sharply on bass: one reading hears it as noticeably deeper and more extended than the original Aria, another hears very little sub-bass gain and prefers the first Aria there. Treble draws the same fork, read either as comfortably tamed and short on sparkle or as energetic with an audible 7-8 kHz peak that can turn sharp. Staging is called impressive for the bracket in some listening and merely average in other listening, and a measured immersiveness sub-score of 3.8 was the weakest of its three audio sub-scores. Comfort is generally good, though at 11.8 g per bud very small ears and pressure-sensitive listeners were flagged as at risk. Verdicts range from a clear recommendation in the bracket to a lateral refresh where the packaging does the persuading.
