The earphones have Y-style cables and no extensions, giving them a lightweight feel. They also come with different sizes of silicone caps to fit any ear, big or small.
According to Radius, these earphones deliver the highest level of sound quality, great durability, and unparalleled style. I don't know about the quality, but judging from the look, these things definitely seem eye-catching.
And you can get them easily, too, as they cost only $20 a pair, which is cheaper than many other earphones. Most importantly, for the money, I don't think you can get anything else that makes your iPod Nano even more colorful.
