JVC HA-S400 and HA-SR500 Headphones

JVC announced the HA-S400 and HA-SR500 on-ear, foldable headphones, which each feature 30mm neodymium driver units with carbon nanotubes which help produce crisp, clear sound. Other key features include soft-cushioned ear pads for comfort and sound isolation, a compact three-way foldable structure for portability, and a lightweight design with a soft headband for comfortable extended listening. The HA-SR500 offers a slight improvement in specs along with a one-button remote and microphone that can be used with iPhone, Blackberry and Android smartphones

JVC says carbon nanotubes diaphragms represent a breakthrough in headphone technology as the material provides a balance of strength and flexibility that cannot be matched by diaphragms made from either metals or plastics. 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 headphones ideal for extended periods of use, while the unique three-way foldable structure makes them 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.

Designed for use on the go with smartphones and other mobile devices, the HA-SR500 features a one-button remote and microphone that can be used with iPhone, Blackberry and Android smartphones. The user-friendly in-line single-button remote control makes it easy to play, stop, skip and answer a phone call, and a microphone is built into the tiny remote control unit. A new “Smart Switch” makes the one-button remote and microphone compatible with most smartphones on the market without requiring a conversion cable.
