Overview

The Zendstanding HA400 is a rugged, metal 4 channel headphone amplifier designed to deliver clean, controlled sound to up to four listeners at the same time. It is powered by a 12V 1A adapter and supports headphones in the 32 to 100 ohms range with comfortable headroom.

Key benefits

  • Independent volume controls on each channel allow friends, bandmates, or students to tailor their listening level without muting others.
  • The low noise JRC4580 op amp helps maintain clear highs and balanced mids across all channels.
  • Four separate outputs reduce crosstalk, making it suitable for shared monitoring during rehearsal, live performances, or classroom demos.
  • Compact metal chassis at roughly the size of a cassette tape makes it easy to tuck into a bag or small rack.
  • Includes a reliable 12V DC adapter for stable power in studios, stages, and homes.

Real world use cases

In a home studio, connect your audio source via the 1/4 inch TRS input and give each musician their own headphone mix. On stage, distribute the click track, vocal, guitar, and monitor feeds to four headphones with independent levels. For remote practice, it sits on a desk or in a backpack and travels between rooms with ease.

Key capabilities at a glance

  • Powerful multi-user listening with individual adjustments
  • Quiet operation for distraction-free monitoring
  • Portable, sturdy metal build for on the go sessions
