The HiBy FC4 is a USB DAC dongle with a built-in headphone amplifier. It connects between your phone or computer and your wired headphones, replacing the device's internal audio circuitry with dedicated hardware.

It is one of the simplest audio upgrades you can make: if you use wired headphones with a modern phone that lacks a headphone jack — or just want cleaner sound from a laptop — a dongle DAC like the FC4 is the natural first step.

  • USB DAC dongle with headphone amplification
  • Restores a high-quality headphone output to jack-less phones
  • Pocketable and plug-and-play
  • Affordable entry into HiBy's DAC lineup at around $60

TonePier is an authorized HiBy retailer shipping brand-new stock, with free US shipping and 45-day returns on every order.

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.
