The iBasso DC04Ultra is a stainless steel USB DAC/amp dongle with dual Cirrus Logic CS43198 chips, 980mW + 980mW at 32Ω from its 4.4mm output, and a 3.5mm jack that also handles mic calls; this set includes both USB-C and Lightning cables. It suits Android and iPhone listeners who want one dongle for IEMs, full-size headphones and voice chat.
Who the iBasso DC04Ultra is for
Full-size headphones on a phone: iBasso rates the 4.4mm output at 980mW + 980mW into 32Ω (6.1Vrms on high gain) with no external power supply needed.
iPhone and Android owners: This set adds a USB-C to Lightning cable to the standard USB-C to USB-C cable and USB-C to USB-A adapter.
Gaming and calls: The 3.5mm jack supports CTIA headset mics, and iBasso says its UAC 1.0 mode works as an external sound card for Switch 2 and PS5.
Hands-on tuning: Three side buttons and a 0.96-inch color display handle volume, filters, gain and channel balance; the Android iBasso UAC app adds a 10-band PEQ.
Skip it if: you want the 10-band PEQ on an iPhone — iBasso's UAC app is an Android APK, so iOS users rely on the on-device controls.
