The ZH3 is Fosi's all-in-one desktop hub: an AKM AK4493SEQ DAC, an XMOS XU316 USB stage, and a fully balanced amp section pushing 2,570mW into 32 ohms from the 4.4mm output. That is enough power for planars and demanding full-size headphones, not just IEMs.

XLR and RCA preamp outputs, three gain levels, bass and treble EQ, six digital filters, swappable op-amps and a remote make it a genuine one-box centerpiece — headphones and powered monitors from the same source, with tone controls when a recording needs them. The three gain settings matter: drop to low gain for sensitive IEMs.

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.
