About the NX7
The Topping NX7 is a portable headphone amplifier, not a DAC, designed to deliver very low distortion and high output power for both sensitive IEMs and demanding full-size headphones. It uses TOPPING’s NFCA amplifier modules, offers three gain settings, and includes both 3.5mm and 4.4mm headphone outputs. Review and retailer sources describe it as a compact, CNC-machined aluminum unit with a built-in 4000mAh battery and up to 20 hours of runtime on low/medium gain. Multiple sources indicate the NX7 has been discontinued.
