The earbuds sport 8mm dynamic drivers with a 20 Hz to 20 kHz frequency response that delivers punchy bass. Furthermore, these aluminum earbuds are magnetic, aiding in the fight against cable tangling when you're not using the in-ear headphones. Eartips are provided in various sizes, as is a charging cable.
