The K5 PRO is a compact gaming DAC/amp that takes USB-C, optical or coaxial input and adds a mic passthrough — an easy sound-card upgrade for a PS5, a Switch or a desktop PC where the onboard jack is noisy.

Physical volume, bass and treble knobs make on-the-fly adjustments simple mid-match, and 24-bit/192kHz decoding with a low noise floor drives headphones cleanly. The mic input is the part console users care about: one box handles game audio and chat without a separate mixer. A sensible first upgrade before spending more on headphones.

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.
