Flagship DAC AKM AK4191EQ+AK4499EX
The Q15 uses a new product from AKM – the DAC combination AK4191EQ+AK4499EX. When working in tandem with the new DWA Routing Technology, sound quality is significantly improved. The result is a more detailed yet natural and realistic sound that makes the listener feel like they have been transported to the concert venue.

Desktop-class portable machine
The Q15 features a new desktop mode of operation, for which a separate Type-C power connector is provided. When connecting the Q15 to a PD adapter, the Q15 will be powered externally, bypassing the battery, allowing it to work in desktop mode even on the road.

1600 mW of power that rivals desktop amplifiers
In desktop mode, the Q15 is capable of delivering 1600 mW of balanced output in headphone mode, which is more than enough to drive a variety of IEMs and full-size headphones.
