Overview
ZTONG ZT-A1 is a portable analog headphone amplifier that takes any source (your phone, your laptop, your existing DAC) and gives it a much more powerful, cleaner output stage. Pair it with a dongle DAC and your IEMs or full-size headphones for a real step up.
Sound & Power
A high-voltage ±6V analog rail drives demanding headphones with authority. Up to 300mW into 32Ω on the single-ended output. THD ≤ 0.0008%. The clean, transparent amplification doesn’t color your music — it just gives it more grip and headroom.
Design & Battery
Compact 140g aluminum block with a precision volume knob, 3.5mm SE output and a 4.4mm balanced output. 4.4mm balanced input is supported for fully balanced signal chains. 12-hour battery, USB-C charging.
