    FAQs.

    +
    Q Is the P40 easy to drive?
    Yes. It runs well on phones and most portable sources. If you want a cleaner background and tighter control, pairing it with a good dongle DAC is the easiest upgrade.
    Q What does “Planar + PZT” add compared to typical hybrid IEMs?
    The miniature planar helps deliver cleaner treble texture and faster transients, while the PZT ceramic unit enhances air, shimmer, and micro-detail—especially on cymbals, strings, and ambience cues.
    Q What kind of sound is it tuned for?
    P40 targets a balanced, natural presentation with strong technical performance: solid bass foundation, clear vocals, and extended, non-fatiguing treble.
    Q Will it hiss on a phone (14Ω)?
    P40 is a low-impedance IEM, so very noisy sources can reveal hiss at high volume. If you notice it, lower system gain, switch devices, or use a cleaner dongle DAC.
    Q 3.5mm or 4.4mm—what should I use? Are both included?
    Use 3.5mm for maximum compatibility. Use 4.4mm balanced if your source supports it and you want extra headroom and control. Both 3.5mm and 4.4mm plugs are included in the box.

    • Custom 7mm Mid Driver.

    • Custom 9mm Bass Driver.

    • Custom PZT Extension.

    • Custom 2nd Gen Planar.

    • 4-Way Hybrid Crossover.

    A dedicated 7mm mid driver focuses on vocal presence and density. The result is cleaner layering in the midrange and a more stable center image.

    The 9mm bass driver is tuned for sub-bass reach without smearing the mids. You get weight and punch, but the low end stays controlled.

    The PZT is used to add extra air and sparkle up top. It helps bring out cymbal shimmer and micro-detail without forcing brightness.

    A compact planar unit improves speed and separation, especially in the upper range. It’s the part that helps fine textures feel “faster” and more defined.

    A 4-way crossover is there to keep the handoff between drivers smooth. That’s what makes the presentation feel coherent—better imaging, less “stitched together” sound.
