5. A method for reducing occlusion in a hearing device placed in an ear canal of a user, the method comprising:

deforming a malleable structure placed in the ear canal to vary a size of at least one channel to adjust a degree of venting provided by the at least one channel,

wherein the malleable structure is sized and configured for placement in the ear canal and has a cross-section shaped to define the at least one channel between the inner wall of the ear canal and an outer surface of the malleable structure;

adjusting the degree of venting in response to one or more of detected feedback or an environmental cue; and

emitting an optical signal from the malleable structure.

6. The method of claim 5 , wherein the optical signal is emitted by a laser photodiode.

7. The method of claim 5 , wherein the malleable structure comprises a gel.

8. The method of claim 5 , further comprising adjusting the degree of venting in response to one or more of detected feedback or an environmental cue.

9. The method of claim 5 , wherein the detected feedback or the environmental cue is indicated from a sensor and wherein the sensor comprises one or more of a microphone, an accelerometer, a vibration sensor, an internal sensor of the hearing device, or a sensor of a control device external of the hearing device.

10. An ear tip apparatus for use with a hearing device, the ear tip comprising:

a malleable structure sized and configured for placement in an ear canal of a user, the malleable structure having a cross-section shaped to define at least one channel between an inner wall of the ear canal and an outer surface of the malleable structure for venting of the ear canal;

an output transducer positioned in the malleable structure,

wherein the malleable structure is deformable to adjust the cross-section thereof so as to vary a size of the at least one channel to adjust a degree of venting provided by the at least one channel; and

an actuator coupled to the malleable structure and operable to cause the malleable structure and operable to cause the malleable structure to deform,

wherein the actuator is configured to vary the degree of venting provided by the at least one channel in response to one or more of detected feedback or an environmental cue.

11. The apparatus of claim 10 , wherein the output transducer comprises an emitter for emitting an optical signal.

15. The apparatus of claim 10 , wherein the actuator is configured to vary the degree of venting provided by the at least one channel in response to one or more of a volume or a sound directionality of an ambient environment.

16. An ear tip apparatus for use with a hearing device, the ear tip comprising:

a malleable structure sized and configured for placement in an ear canal of a user, the malleable structure having a cross-section shaped to define at least one channel between an inner wall of the ear canal and an outer surface of the malleable structure for venting of the ear canal;

an output transducer positioned in the malleable structure,

wherein the malleable structure is deformable to adjust the cross-section thereof so as to vary a size of the at least one channel to adjust a degree of venting provided by the at least one channel,

wherein the malleable structure is deformable between a low cross-sectional area configuration and a high cross-sectional area configuration, the at least one channel providing more venting when the malleable structure is in the low cross-sectional area configuration than when in the high cross-sectional area configuration.

17. The apparatus of claim 16 , wherein the output transducer comprises an emitter for emitting an optical signal.
