An earpiece 2 comprisesg an earbud, which is arranged such that it may be inserted into the ear canal of a user (see figs 5-7). The earpiece housing includes at least one microphone that is arranged to sample the ambient environment through a port 5. The earpiece is arranged such that when the earbud is inserted into the ear canal of a user the microphone samples the ambient environment between the earpiece and the concha. This is said to reduce the effects of wind noise, etc. The port 5 remains open because the protrusions or ribs 15, 16, 17 keep the concha away from the port. |
