Sell Your Used Audio Interface — 0% Fees

A used audio interface typically sells for £40 to £200, and on WishThrift it costs you nothing to list — no fee, no commission, so you keep the whole amount you agree. Audio interfaces sell on input count and whether the drivers still support current operating systems, and the second point is what catches buyers out.

The short version

Typical range: £40 – £200 — see the full audio interface value guide
What decides your price: condition, and how well you evidence it in photographs
Cost to sell here: nothing, at any price

Before you photograph it

Ten minutes here is worth more than anything else you will do. Buyers are deciding between your listing and someone else’s, and preparation is what visibly separates the two.

Note the model, the number and type of inputs, and the connection: USB, Thunderbolt or FireWire.
Check the manufacturer still publishes drivers for current operating systems and say what you find.
Test every input and output, all gain controls, and the phantom power.

The photographs that sell an audio interface

Four photographs do almost all the work. Shoot in daylight, near a window, with the item against something plain — and do not use the flash, which flattens texture and hides exactly what buyers are trying to see.

The interface from the front, controls visible
The rear panel showing all inputs and outputs
The connection port and any bundled cable
Any worn label, damaged socket or scuffed case

Photograph the flaws too. It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover. Buyers who can see the damage stop imagining something worse.

Writing the title and description

Brand, model and I/O: “Focusrite Scarlett 2i2 3rd Gen Audio Interface, USB-C”. Generation matters because driver support differs. State the input count and whether the preamps have phantom power, which is what recording buyers need.

Then state these in the description, because a buyer who has to ask is a buyer who might not bother:

Brand, model, generation and connection type
Number and type of inputs and outputs, and whether phantom power is available
Current operating system driver support
Whether the cable, power supply and any bundled software are included

What buyers will actually ask

You will receive the same three messages about an audio interface. Answering them in the listing itself removes the back-and-forth, and answering them well when they do arrive is what turns an enquiry into a sale.

“Does it still have driver support?”

Check the maker’s current downloads page and say what you found. An interface without modern drivers is effectively unusable, and this is the thing buyers get caught by.

“Does phantom power work?”

Test with a condenser mic if you can. It is essential for most recording setups and a failed 48V supply is a real fault.

“Is the cable included?”

Confirm the connection type and whether the cable comes with it. Older interfaces sometimes need adapters buyers will not have.

Pricing it so it actually sells

Start from the honest condition grade rather than the price you hope for. WishThrift listings use five grades — New with Tags, Like New, Good, Fair and For Parts — and what each grade means is worth reading before you choose, because grading up is the most expensive mistake sellers make. It does not raise the price; it produces a buyer who arrives expecting something else.

The audio interface value guide prices all five grades for this item. Pick your grade, take the figure, and if you sit between two grades price toward the lower one. Items priced honestly sell faster than items priced hopefully, and on a free platform there is no fee eating the difference anyway.

What you keep, compared

On a £120 sale — roughly the middle of the range for an audio interface — here is what the commission-charging platforms would take, and what you would keep on each:

Where you sell it	Fee	You keep
WishThrift	£0	£120
Poshmark	−£24	£96
eBay	−£16	£104
Mercari	−£12	£108
Etsy	−£8	£112

Seller-side rates verified 26 Jul 2026 — Poshmark: 20% commission on sales of $15 and above; eBay: 13.6% final value fee, plus a per-order fee; Mercari: flat 10% selling fee; Etsy: 6.5% transaction fee, plus a listing fee and payment processing. Percentages are applied to the sterling figure above; the fixed per-order and processing charges those platforms add are quoted in their own currency and are not included here, so the real deductions are slightly larger. Full breakdown: marketplace selling fees compared.

Timing and getting it to the buyer

Steady all year with a Christmas lift. Recent USB models sell within days; older FireWire units sell slowly because of connectivity.

Compact and easy to post. Include the correct cable and any power supply, and photograph what goes in.

WishThrift does not process payments or arrange delivery — you and the buyer agree both directly — so confirm payment has cleared before the item leaves your hands, and keep the conversation on the site so there is a record of what was agreed.

Frequently asked questions

What is a used audio interface worth?

Typically £40 to £200 depending on brand, generation and input count. See the audio interface value guide.

Why does driver support matter?

Interfaces need manufacturer drivers to work with current operating systems. When support ends the device becomes unusable on new machines, so check the maker’s download page and state what you found.

Are older FireWire interfaces worth selling?

They sell, but slowly and cheaply, because modern computers lack the port and drivers are often discontinued. Be upfront about both so the right buyer finds it.
