Title

The Questyle M18i is a portable headphone amplifier and USB DAC that works both wired and over lossless Bluetooth, with support for Android and iOS. Questyle builds current-mode amplification into its portables, and the M18i is the model that lets you use it without a cable tethering you to the phone.

The dual-mode design is the selling point: run it wired at the desk for the cleanest path, then go Bluetooth when you're moving around without dropping to phone-grade sound. Cross-platform support means it survives a phone change. This is a step above dongle territory in both capability and size — the right call if you're driving demanding IEMs or a portable-friendly headphone and want real amplification on the go.

  • Portable USB DAC and headphone amplifier
  • Lossless Bluetooth operation
  • Works with Android and iOS devices

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.
