The Castor runs two dynamic drivers per side with Harman-style tuning, which keeps vocals and instruments in proportion while still delivering the bass emphasis KZ buyers expect. This is the bass variant, in the version without a microphone.

The detachable 2-pin cable is the practical detail worth noting: cables are the first thing to fail on budget IEMs, and here a replacement costs a few dollars instead of the whole set. A sensible everyday pair, and an easy upgrade path if you later want a balanced 4.4mm cable.

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.
