HIFIMAN HE400S

General Features:

• Wired Lightweight Stereo Headphones
• Over-ear design
• Large Planar Magnetic speaker driver produces amazingly clear sound
• Detachable cable for easy storage
• Adjustable headband for comfortable listening sessions
• Gold-plated, corrosion-resistant stereo jack
• NOTE: With this remarkable sensitivity, HE400S does not require a large amplifier. In fact, best results will be achieved if you use this particular model with a high quality amp of moderate power. We recommend not pairing HE400S with an amp that has an output of 500mW per channel or greater. If HE400S is paired with too much power, distortion or damage can result so choose high quality and moderate power. It sounds terrific driven right from a smartphone.
