1. An insertable in-ear earphone configured as a hybrid transparency system, the insertable in-ear earphone comprising:
a user content sound system to receive an audio signal, and convert the audio signal into a user content sound for delivery into an ear in which the in-ear speaker has been inserted;
an ambient sound augmentation system having an external microphone which is configured to pick up sound in the ambient environment of the in-ear speaker, as a microphone audio signal, wherein the system is activated to process the microphone audio signal before converting the microphone audio signal into an ambient content sound for delivery into the ear, and to increase a gain of a plurality of frequency components of the microphone audio signal in accordance with a profile comprising a plurality of acoustic characteristics associated with the ear;
a valve that can be configured between i) an open state and ii) a closed state;
an active noise control (ANC) subsystem that is activated to produce anti-noise for delivery into the ear; and
logic to signal the valve into the open state while activating the ambient sound augmentation system, and then signal the valve into the closed state while activating the ANC subsystem.
