Edition 01 / 2026 Fig. A · The X15

Sound, quietly considered.

The X15 — a 14.2mm quad-magnet driver, forty hours of play on a 470mAh case, Bluetooth 5.4, and 0.02 seconds of honest sync. Carried lightly, at 4.2 grams a bud.

The Voxhuma X15 earbuds in their matte case X15 · FIG. A Matte / Charcoal

We built a small thing, slowly. A pair of earbuds with four moving decisions: the driver that sits behind the sound, the case that carries it, the fit that disappears, and the surface that answers to a tap.

Everything else, we left out. The X15 is a catalog object first and a product second — a piece of daily design we wanted to keep around.

Studio Voxhuma — Cheyenne, WY

Four
decisions,
well made.

Every element of the X15 was chosen before it was engineered. The driver, the case, the fit, and the surface — four deliberate pieces, and nothing extra between them.

A driver tuned by hand, not by committee.

Fourteen-point-two millimeters, four magnets, one honest curve. The X15 holds a warm low end, a clear midrange, and a top that stays out of its own way.

Forty hours, a fifteen-minute top-up.

Six hours on a single charge. Forty from the 470mAh case. Fifteen minutes on the cable returns ninety more — and the LED on the front tells you exactly where you stand.

Bluetooth 5.4 — quietly stable.

Flash pairing, a signal that holds through walls, and a latency of twenty milliseconds end-to-end. Film stays in sync, calls hold, games answer honestly.

Four-point-two grams — then forgotten.

Soft silicone in three sizes, a surface that answers to touch, and a shape built to stay put through a run, a flight, or a long afternoon.

What people say,
unedited.

A few notes we liked, from owners who've carried the X15 through a run, a commute, a flight, or a long studio week.
The first pair I haven't had to take off during a long flight. Light, balanced, and the case disappears into a jacket pocket.
Maren Oduya Industrial designer · Chicago
I use these for mixing demos on the train. The low end is honest — tight where it should be, never artificially boomy.
Daniel Reyes Producer · Brooklyn
The touch surfaces just work, the case outlasts my week, and the whole thing looks like something I'd buy at a design store. Not much else to add.

Asked often,
answered plainly.

Everything else, write to info@voxhuma.com. We read every note.

Every Voxhuma X15 is covered by a two-year limited warranty against manufacturing defects, starting from the date of purchase. If something isn't right, write to info@voxhuma.com and we'll arrange a replacement.
The X15 ships with soft silicone tips in three sizes — small, medium, large. Each bud weighs 4.2 grams, which most wearers describe as barely-there. If the included sizes don't work, our thirty-day return window has you covered.
Six hours of continuous play on a single charge. With the 470mAh case, that extends to around forty hours total. A fifteen-minute top-up returns roughly ninety minutes of additional play.
Each bud has a built-in microphone tuned for voice clarity. We've optimised signal stability on Bluetooth 5.4 so calls stay connected indoors, outdoors, and on the move.
End-to-end latency sits at 0.02 seconds — about twenty milliseconds. That's fast enough that dialogue, streams, and casual gameplay stay in sync without any noticeable drift.
Thirty days from delivery to return the X15 in its original condition for a full refund, no questions asked. Details on our returns page.
