Extremely small and light, with perfect fit and high soundproofing qualities. It is situated close to the user's eardrum and is exceptionally airtight. This model offers high resolution, a vast soundstage, and clear bass.

By bringing the driver unit closer to the eardrum, a more realistic, lively sound quality is achieved. In the F3100, we have precisely minimized the casing with a design consisting of the minimum possible elements. With a diameter of 5.5 mm, the casing is finished with a hard anodized film of aluminum-magnesium alloy, which helps in reducing the weight.
