HiFiMan HE-6 Headphones Unmatched Musicality and Transparency That's Worth Every Penny A Huge Step Above the Rest: Ultra-Sensitive and Revealing Performance The HE-6 is HiFiMan's flagship design, a no-compromise approach that creates gorgeous soundscapes with lifelike presence. Considered by many to be the world's finest headphone, the HE-6 features HiFiMan's proprietary planar magnetic technology in a no-compromise design. It is the reference choice of critical listeners around the world. Unfortunately, the efficiency of the HE-6 is so low, it requires more power than most headphone amps provide. The solution: HiFiMan designed the small HE-Adapter box that connects the headphones via speaker wire to an integrated or power amplifier. "HiFiMAN's new HE-6 is a world-class headphone that, though certainly not cheap, is reasonably priced for the quality on offer. Enthusiasts seeking the very best of the best would be wise to include this headphone on their 'must audition' lists." - Chris Martens, Playback, Nov. 2010 Silky smooth treble, wicked-fast transients, deep propulsive bass, and a midrange so sweet it'll bring tears to your eyes. HiFiMan's HE Series headphones use a featherweight diaphragm driven by a massive magnet structure that makes ordinary headphones sound slow and bloated. "The HE-6 reminds us of hyper-revealing loudspeakers like the MartinLogan CLX, but with the ability to deliver deep, powerful bass on demand." - The Absolute Sound, "2012 Editors' Choice Awards"
