AZLA will release SednaEarfit XELASTEC II for AirPods Pro 3 on March 6, offering six sizes across set or single-size packages priced ¥3,190–¥4,290.
Developed using analysis of 788 ear canals and tens of thousands of tests, the ear tips optimize AirPods Pro 3 performance through refined material, shape, and fit.
The premium custom TPE material softens with body temperature for adaptive sealing, yet resists deformation better than standard TPE for long-term comfort and stability.
AZLA’s approach with the XELASTEC II for AirPods Pro 3 reads less like an accessory refresh and more like an exercise in system matching. The geometry of the sound bore and the stiffness gradient of the TPE appear tuned to the acoustic impedance of Apple’s short-nozzle design, where even small changes in insertion depth or seal compliance can shift upper‑mid presence and low‑frequency pressure. Compared with generic third‑party tips that often over-damp the treble or exaggerate sub‑bass bloom, this design philosophy prioritizes maintaining the AirPods Pro 3’s native tonal balance while stabilizing the acoustic load seen by both the driver and the inward-facing microphones used for ANC and spatial audio processing.
Another notable point is the integrated adapter architecture, which subtly alters how mechanical energy is managed at the nozzle interface. By eliminating a separate mounting sleeve, micro-movements between the tip and the stem are reduced, which in turn can minimize seal fluctuation during jaw movement—an issue frequently discussed in enthusiast circles with true wireless designs. This has downstream effects not only on bass consistency but also on how convincingly head-tracked spatial cues remain anchored. The tapered wall structure further contributes by lowering insertion resistance without collapsing the tip, a balance that uniform-thickness designs often fail to strike when paired with smooth, shallow-fit earbuds.
Finally, the updated filter geometry suggests attention to airflow linearity rather than simple debris protection. Multi-geometry patterns can distribute pressure more evenly across the bore, reducing turbulence that might otherwise smear transients or subtly attenuate upper harmonics. In practice, this kind of refinement is less about dramatic “sound changes” and more about preserving resolution and coherence under real-world wear conditions. From an audiophile perspective, the XELASTEC II positions itself not as a flavor-altering tweak, but as a control component—one intended to let the AirPods Pro 3 behave closer to their intended acoustic reference across longer listening sessions.
