Palavox Akasha Review: Your Haven, Your Ethereal Sound
We at About Audio previously reviewed the Palavox Dark Knight, which was one of the most pleasing flagship IEMs of the year – yet that was the second one! Dark Knight left enough of an impression to make me want to go back and hear where the brand started. So here we are with the Palavox Akasha, Palavox’s TOTL IEM that built the brand’s reputation before the Dark Knight arrived. Akasha is a 13-driver quadbrid using 1DD+6BA+2BCD+4EST, priced at $4,200.
The Meaning of the Name “Akasha”
The name comes from the Akashic Records, an ethereal archive said to hold the history of every soul, thought, and event in the universe. The word Akasha itself is Sanskrit for “ether” or “sky”, and the concept describes a kind of universal library that sits outside of time and space. Palavox carried this idea into the design, and you’ll see it reflected in the enamel work on the faceplates. Let’s see what the Akasha has to offer, how it sounds, and how it holds up against Dark Knight and other competitor flagship earphones.
About Palavox: Who are they?
For those who missed our Dark Knight review, Palavox is a Chinese audio brand founded in 2025 by Michael Fu, a senior acoustic engineer with over a decade of R&D experience. The brand name combines “Paradise” and “Voice”. Michael’s background is in OEM/ODM work, and Palavox was founded as the outlet for his own designs rather than someone else’s. Palavox is also often mentioned alongside Artpical, though the two operate independently, with Palavox handling the high-end side.

Packaging / Accessories
Akasha arrives in a presentation similar to what Palavox later did with the Dark Knight. The earpieces sit in the top layer alongside a garment ring accessory that ties into the product concept, and the rest of the accessories are placed underneath. The box includes a hard storage case, the 1.2m stock cable, 9 pairs of three different style eartips, and paperwork.
The Earpieces (1/3): Specs and Features
Akasha is a 13-driver quadbrid running 1DD+6BA+2BCD+4EST. A single 10mm PU+LCP dynamic driver takes the lows, six Knowles balanced armatures handle the mids and highs, and four Sonion electrostatic drivers cover the ultra-highs. Two Sonion bone conduction drivers sit alongside them for physical resonance and depth. It’s a driver setup that leans on Sonion and Knowles for everything above the dynamic driver, which is a fairly conservative choice of parts for a debut product, and reasonably so.

Cable Connectors: 2-pin 4.4mm, 1.2mm
Acoustic Structure (2/3): Semi-Open Chamber and Vent Balance
The internal cavity is 3D printed at high precision to hold the drivers in alignment, which is the same manufacturing approach Palavox carried into the Dark Knight’s acoustic chambers later on. Akasha uses a semi-open rear chamber with pressure relief, paired with a front vent balance system. Semi-open designs generally trade a bit of isolation for airflow and a more open presentation. Palavox states the arrangement also reduces listening fatigue.
The Earpiece Design and Ergonomics (3/3)
Shells are machined from Titanium TC4 using 5-axis CNC. The faceplates carry handmade enamel inlays with titanium plating, and the nozzle is DLC-coated. Enamel work on a faceplate is unusual at any price, and it’s the part that separates Akasha visually from the machined-metal look that most titanium flagships end up with. The Dark Knight went for a spaceship theme with red air grills, whereas Akasha goes for something more ornamental.
Beautifully-crafted, Custom-grade Stock Cable
Akasha comes with a custom-grade stock cable built in a coaxial structure, mixing pure silver with silver-plated single crystal copper. It’s terminated in a 0.78mm 2-pin with a 4.4mm balanced plug, at 1.2m length. Palavox went with a more expensive conductor mix here than the SPC 6N OCC copper cable that later came with the Dark Knight.
