Title

The Whizzer Opera Factory OS1Pro is a wired in-ear earphone made for everyday music listening — the kind of pair you leave in a bag or a jacket pocket and don't think twice about.

Wired means no charging and no pairing: connect it to a phone, laptop, DAP, or dongle DAC and it plays. If you already own a nicer set for critical listening, the OS1Pro is an easy second pair for the office, the gym bag, or travel where losing an expensive IEM would sting.

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.
