Overview
ZTONG ZT-D20 is our flagship portable music player. Dual AKM AK4499EX DACs feed a balanced 4.4mm output capable of up to 720mW into 32Ω — enough to drive demanding headphones and flagship IEMs with authority. Android 14, a 5.5-inch 2K touchscreen, Wi-Fi 6 and Bluetooth 5.3 make streaming and local Hi-Res one and the same device.
Sound & Power
Up to 32-bit / 768kHz PCM and DSD512 native. The dual AK4499EX architecture is renowned for its musical, natural character with deep detail retrieval. Up to 720mW into 32Ω on the 4.4mm balanced output gives real authority with planar and high-impedance loads; 3.5mm single-ended covers classic IEMs. THD is held below 0.0005% across both outputs.
Design & Connectivity
Aviation-grade aluminum unibody chassis in deep graphite, with a knurled precision volume wheel, side function buttons, and a 5.5-inch 2K (2160 × 1080) touchscreen. Wi-Fi 6 dual-band and Bluetooth 5.3 with LDAC, aptX HD and aptX Lossless support. 6000mAh battery delivers up to 12 hours of playback. 256GB internal storage plus microSD expansion to 1TB.
