Bose's own TriPort technology is incorporated to help provide maximum low-end presence within the unit's lightweight enclosure, working to provide optimal acoustic equalization for fine-tuned response between bass, middle and treble frequencies. The OE2's slim headband memory foam ear cushions promote user comfort throughout extended listening applications, minimizing discomfort that may be caused through heavier, bulkier components. For storage purposes, an simple fold-flat collapsible design has been implemented for quick storage and maximal protection between listens. A zippered protective case is also included.
