A transducer is mounted in the main bass reflex chamber at a transducer enclosure portion of the main bass reflex chamber. An earbud insert is mounted to the main bass reflex chamber and receives sound from the transducer. The earbud insert has an earbud opening formed at an earbud tip of the earbud insert. The earbud opening connects to an earbud channel. A stem extends from the main bass reflex chamber. The stem has a reflex connector channel. A reflex module is attached to the stem selected from either: a first reflex module removably secured to the stem of the main bass reflex chamber; or a second reflex module removably secured to the stem of the main bass reflex chamber when the first reflex module is removed from the stem of the main bass reflex member."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Headphone","description":"A headphone has a main bass reflex chamber formed inside a housing sidewall.
