Title

The Questyle M15C is a portable USB DAC and headphone amplifier built around the CS43198 converter — a dongle-class device from a company better known for its desktop current-mode amplification work.

This is the piece that sits between a jackless phone or laptop and your IEMs, replacing whatever converter is baked into the host device. If you've been running multi-driver hybrids or planar sets straight off a cheap adapter, a proper dongle DAC like this is usually the most audible upgrade available for the money.

  • Portable USB DAC and headphone amplifier
  • CS43198 DAC chip
  • Drives IEMs and headphones from phones and laptops

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.
