Open headphones with active noise cancellation

A wearable apparatus comprising:

• a first structure configured to contact a head at a first location and at least partially surround a first ear;
• a second structure configured to contact the head at a second location and at least partially surround a second ear;
• a third structure linking the first structure to the second structure;
• and
• a housing coupled to the first structure such that a first edge of the first structure and a second edge of the housing are separated by a first distance, the housing including(i) an audio transducer configured to generate output audio, (ii) an acoustic structure having a funnel shape and configured to direct the output audio towards the first ear, and (iii) a microphone coupled to the acoustic structure, wherein a wide opening of the acoustic structure faces the audio transducer and a narrow opening of the acoustic structure faces the first ear.
