The HE-400i planar magnetic headphone from HiFiMan.  HiFiMan took all the great features of the already acclaimed HE-400 and improved upon them, with a particular focus on fit and ergonomics.  Claiming to be 30% lighter than most other planar magnetic models, the HE-400i will be one of the very lightest planar magnetic headphones available.  The newly-designed headband has improved pressure points, and the all new FocusPads, a beveled pleather and velour hybrid, will make these headphones more comfortable for long term listening sessions.  The smoky gray earcups with their contemporary glossy finish also fold flat for convenient storage and transport.  And don't forget HiFiMan's signature refined sound quality available at excellent price points.  The new HE 400 i are shaping up to be an affordable premium headphone choice, or another great addition to any headphone lover's collection.
