The Questyle M18i is a portable Bluetooth DAC amp that also works as a wired USB DAC, with lossless Bluetooth and support for Android and iOS. Built around Questyle's current-mode amplification, it suits listeners driving demanding IEMs or portable-friendly headphones who want real amplification on the go.
Who the Questyle M18i is for
Desk by day, Bluetooth on the move: Run it wired at the desk for the cleanest path, then go Bluetooth when you're moving without dropping to phone-grade sound.
Demanding IEMs and portable headphones: It sits a step above dongle territory in capability, for real amplification on the go.
Switching phone platforms: Android and iOS support means it survives a phone change.
Skip it if: You want the smallest possible DAC; the M18i is a step above dongle territory in size as well as capability.
vs xDuoo XD05 Basic 2: Both stream over Bluetooth, but the XD05 Basic 2 uses a socketed, swappable op-amp, while the M18i relies on Questyle's current-mode amplification. Pick the XD05 Basic 2 for op-amp rolling.
vs ONIX Beta XI2: The Beta XI2 is a dongle powered by your phone or laptop; the M18i is larger than dongle class and also runs over lossless Bluetooth. Pick the Beta XI2 for compact wired use.
