This headphone's open-air design lets you enjoy full, rich stereo sound without the boxy, "closed-in" feeling imparted by many closed-ear headphones. An open-air design prevents unwanted resonance from coloring your music. While great for home listening, the JF40 may be inappropriate for public portable use, where the open-air design will make your music audible to others and will do nothing to keep external noise from interfering with your listening.
The headphone's 40mm elements and neodymium drivers are perfect for dynamic reproduction of digital sources, and a self-adjusting headband ensures a comfy fit.
A single-sided, 7-foot cord grants freedom of movement, while a volume control (with mute!) lets you adjust your listening at some remove from your source player.
A nice touch is a gold-plated minijack terminus, whose .25-inch stereo adapter facilitates hookup with component equipment. Jensen covers the headphone with a lifetime warranty.
