Q15预热图-EN.jpg


After 4 years, the upgraded model of the Q5S, the Q15, is finally coming out.

We first use AG glass for the Q15’s back panel, which is anti-scratch and anti-fingerprint with a delicate touch. Coupling with the golden size ratio of 18:9 makes it comfortable to use both when being handheld and when bundled with other portable devices.

The Q15 is not only easy to hold, but also features desktop-grade technical features and strong performance.

The Q15 features a new desktop mode, sporting a separate Type-C power connector for it. When the Q15 is connected to the PD power adapter, the Q15 will be powered externally completely bypassing the battery, allowing for a desktop-like experience even on the go. When put in Desktop Mode, the Q15 under balanced output is capable of putting out 1600MW in enhanced over-ear headphone mode, which is more than enough to easily drive various IEMs and full-size headphones.

There are 3 days left before the DAC and Headphone Amplifier Q15 comes out. Let's stay tuned!

It will be interesting to see how this compares to the Q7, given that it kind of looks like a mini-Q7. Will it effectively be a Q7 without DC power and an "Ultra Gain" mode?

The Q15 is the only model among products of the same grade that features AKM’s newest DAC combination - the AK4191EQ+AK4499EX. When working in tandem with the newly developed “DWA Routing Technology”, audio performance is greatly improved. The result is a more detailed, yet natural and realistic sound that makes the listener think they have been transported to the concert site.

output power without "desktop mode": 340mW BAL and 85 for SE.

what amp tech is used?

And why Fiio do not used LHDC codec? LHDC much better than LDAC
