Overview
ZTONG ZT-D2 is the bigger sibling of ZT-D1: dual ES9219 DACs, more output power, and a focus on driving the most demanding IEMs and headphones from any USB-C device.
Sound & Power
Up to 32-bit / 384kHz PCM and DSD256. THD below 0.0004%. Up to 80mW into 32Ω on the 4.4mm balanced output — enough to comfortably drive planar IEMs and full-size headphones that ZT-D1 struggles with. 3.5mm single-ended for classic IEMs.
Design
Same compact aluminum shell family as ZT-D1 but with the wider end of the body to accommodate both 3.5mm and 4.4mm jacks side by side. USB-C bus powered — no battery, no app, no fuss.
