Bose 627479-0040 SIE2i Sport Headphones - Purple

The Bose SIE2i Sport Headphones in Purple are built around Bose's TriPort acoustic structure, which uses external ports to vent the ear cups and produce fuller bass and more natural sound than typical sport earbuds of comparable size. The StayHear ear tips—available in small, medium, and large—use a wing-shaped design that rests in the outer ear's ridges rather than pushing deep into the ear canal, providing a secure hold during running, cycling, or gym workouts without the pressure and discomfort of traditional in-ear seals.

Sweat and weather resistance means the SIE2i can handle rain-soaked runs and heavy perspiration without degrading performance. The inline remote and microphone allow one-touch control of music playback and phone calls, though full functionality is optimized for select Apple devices—Android users may find volume and track controls unresponsive. The bundled Reebok fitness armband keeps your phone accessible on your arm, while the clothing clip and extension cable help manage cord length and prevent snags. As a wired sport earphone, the SIE2i requires a 3.5mm headphone jack, which limits compatibility with many current smartphones unless paired with a Lightning or USB-C adapter.
