Expert Audio Engineering Commentary
Headroom notes
Same two-mode trap as the KA17, but wider: 5 mW into 300 ohms on phone power against 19.5 mW in Desktop Mode, a 2x voltage difference from one line of the same table. Phone-mode numbers are recorded. The 2.3 Vrms figure quoted in most shop listings is the Desktop-Mode value and does not apply to a phone.
Amplification Warning
Output impedance is <1.7 ohms on 3.5 mm — high enough to shift the tonal balance of a multi-driver IEM whose impedance curve is not flat. This is not a dongle for 8-ohm balanced-armature sets.
