Parts, terms and repairs

Everything on this page is a number or a price rather than a promise. If a part is not listed, it is because it has not worn out for anyone yet — ask, and we will find it.

  • Two years, five if registeredRegister within a month and we add three.
  • Parts for ten yearsFrom the last unit sold, not from launch.
  • Quoted before we startOut of warranty work is priced first, always.
  • Old parts returnedWhatever we replace comes back in the box with it.

Warranty

The extended term costs nothing and needs a serial number within a month of delivery. Wear parts are called out because a cell is not a fault.

Currently between production runs

Read straight from the catalogue, so it cannot disagree with the product page. No deposits and no waiting list — it goes back on sale when it exists.

Questions

Where is the raw measurement file?

On every product page, under the spec table, as a CSV. It is the median of five production units at 1/12 octave, ungated and unsmoothed beyond that. No account needed to download it.

My unit is out of warranty. Will you still repair it?

Yes, at any age, as long as we have the part — and we hold parts for ten years after the last unit of a model ships. We quote before we start and we return the old components in the box.

Does a firmware update change how it sounds?

No. Firmware fixes bugs and adds codecs. The tuning is fixed in hardware and the curve you measured on day one is the curve it keeps. If we ever needed to change an acoustic behaviour we would ship it as an opt-in profile and say so plainly.

Can I fit third-party pads or switches?

You can, and it will not void anything. Pads change the frequency response — usually in the 2–5 kHz region — so the published curve stops describing your unit. That is a fair trade if you prefer the result.

Something arrived faulty.

Tell us within thirty days and we send a replacement before we ask for the original back, with a prepaid label in the box. There is no diagnostic process to go through first.

How do I register for the extended term?

Serial number and order number, within a month of delivery. That is the whole form. We do not use it for anything else and there is no newsletter attached to it.

If none of that covers it

Two people answer support and both of them have built the products. Include the model and the serial from the sticker under the headband or inside the case, and skip the description of what you already tried — we will ask if we need it.

Replies within one working day, and a real answer rather than a ticket number.
