Paired with 30mm neodymium driver units the nanotubes diaphragms enable the HA-S400 to deliver exceptionally crisp, detailed full-range sound, particularly in the mid-high frequency range, and vivid, deep bass. The lightweight design and soft headband make the HA-S400 ideal for extended periods of use, while the unique three-way foldable structure makes the HA-S400 compact and portable. Additionally, the on-ear design helps to effectively block out background noise while also providing a comfortable fit with the soft cushioned ear pads. Other features include 1.2m cord with gold-plated iPhone-compatible slim stereo plug.
