Perfect for rock and metal. Smooth, relaxing tuning, great bass with good slam, rich mid-range, safe treble. Upper mids may be too relaxed for some, treble is a bit dark.Gizaudio Axel original ranking

High volume set, very immersive, scales great with no sharpness, wide staging, enough detail/extension, good bass, just crank it up and enjoy the music. Jays Audio Youtube Channel

This is a unique sound, for neutral I prefere Airoso. Jaytiss Youtube Channel
Reverby, bouncy, and extended decay in the sub-bass. Unique bass play back and adds more texture to the low-end. Although reverb can bleed into the vocals - maybe the drivers work too well lol. A bassier 5+2 with better texutre and scaling. Jays Audio Youtube Channel

The Kiwi Ears Étude offers a distinctive listening experience centered around its Kiwi Vibration Transducer (KVT), which adds a subtle tactile sensation to bass frequencies. This isn’t a gimmick—it lends sustained notes like bass guitars or synth lines an organic, textured quality that feels immersive without overpowering the mix. That said, the KVT can introduce mild reverb in lower-mid frequencies, occasionally coloring male vocals in podcasts or sparse tracks.
Tuning-wise, the Étude follows a mild V-shaped signature with an 8dB sub-bass lift and smooth, relaxed treble. The midrange remains relatively neutral, though vocals can lack body in acoustic tracks without bass accompaniment. While the beryllium dynamic driver delivers punchy kicks, the real star is the KVT’s physicality, which creates a holographic low-end that enhances EDM and hip-hop. Technical performance is competent for the price, with average soundstage width and decent separation, though imaging lacks precision.
Fit may be divisive due to the large shells housing the transducer, and the nozzle’s lack of ridges limits eartip options. Source pairing is critical too: the KVT scales noticeably with powerful amplification, unlocking fuller dynamics. Despite quirks, the Étude succeeds as a fun, genre-specific IEM that stands out in a crowded market.
