Apple redesigned its signature headphones today, with a new geometry that’s made to better fit the ear. They don’t seal like in-ear phones, however, and have three ports designed to maximize air flow through the design.
A port in the back is aimed at delivering better mid-tones, and there’s one in the stem and the primary one for delivering sound to the inside of your ear. It’s all aimed at delivering the best sound possible.
These ship today on their own, and are included with new iPods and iPhone. They’ve gotta be better than the existing ones, but I’ll reserve judgement about how much better until I get actual ears-on experience.
