Narrative:

During an otherwise ordinary approach procedure; portions of both doors departed the aircraft. Due to the orientation of the door fragment on my side; my headset departed my head. The pilot in the right seat attempted to return them to my head but I could not hear over the wind noise and shortly thereafter they departed my head again. I was also unable to communicate with the pilot in the right seat due to the noise generated by the remaining fragment of the door. Although the aircraft can be flown without doors I was unsure the impact of the partial door on flight characteristics and with the inability to maintain communication; I decided to land on the nearest suitable runway surface. I felt the right seat pilot tugging at the controls and interpreted his tugs to cancel my approach and enter left traffic for runway xx; which I then did and performed a short approach.
