Title

The Fosi Audio DS1 is a mini portable USB-C DAC and headphone amplifier handling DSD512 and 32-bit/768kHz decoding in a dongle-sized package.

It's built for the phone-and-IEMs crowd: plug in, skip the built-in audio path, and get proper decoding without adding a brick to your pocket. Also a sensible laptop companion for travel, or a backup source to keep in the bag when your main DAP is charging.

Frequently asked questions

Is this unit genuine?

Yes. TonePier is an authorized retailer — every unit comes from the brand or its official distributor, carries a valid serial number and is covered by the full manufacturer warranty.

How long does shipping take?

SKUs stocked in our US warehouse ship within 1–2 business days. Items shipped direct from our China hub typically arrive in 8–15 days with full tracking. The product page tells you which applies before you order.

What if it isn't for me?

You get 45 days to decide. Keep the packaging, keep it in like-new condition, and send it back for a refund. Ear tips unsealed for hygiene reasons are fine — we expect you to actually listen.
