The Fosi Audio K7 is a Bluetooth gaming headphone amplifier and USB DAC with a microphone input, built for PS5, PC and Switch — and with enough grunt to drive planar headphones, which most console-oriented boxes cannot claim.

The mic input is the part gamers care about: one device handles both directions, so you are not splitting a headset across a mixer and a DAC. Bluetooth gives you a second, cable-free source for music between sessions, and the planar-driving capability means you can bring a real audiophile headphone to the desk instead of a gaming headset.

  • USB DAC and headphone amp with mic input
  • PS5, PC and Nintendo Switch compatible
  • Bluetooth input; capable of driving planar headphones

Authorized Fosi Audio stock, 1-year warranty, 45-day returns.

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.
