Abstract
In-ear active noise-cancelling (ANC) earphones for which the ANC circuit remains stable even under varying wearing conditions, the earphones being worn so that an eartip of the earphone is at least partially in the external auditory canal, with at least one speaker with a frontal volume leading to a tip area and/or speaker channel, and with at least one ANC microphone. To ensure that the ANC circuit remains stable even with a small available space, the earphones feature the connection of a frontal volume and/or a speaker channel with an additional volume via a tube ending in the tip area.
