Title

The Fosi Audio DS2 is a mini USB DAC and headphone amplifier dongle supporting playback up to 32-bit/768kHz. It is the pocket-sized fix for phones and laptops that either lack a headphone jack or have one that is not worth using.

Dongles like this are the highest-value upgrade in the hobby for most people: plug it between your phone and your IEMs and the noise floor drops while the drive improves. Keep one in the laptop bag as a travel source even if you have a full desktop stack at home.

  • USB DAC and headphone amplifier in dongle form
  • Up to 32-bit/768kHz playback support
  • Pocketable travel and phone source

Authorized Fosi Audio retailer, 1-year warranty, free US shipping over $49.

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.
