Bose Sport Earbuds are designed from the ground up to energize your exercise with acclaimed lifelike sound and a comfortably secure fit. Proprietary technologies make your music sound clear and balanced, no matter how loud you turn it up. The earbuds’ sleek design allows them to sit close to your ears. And the eartips won’t hurt your ears no matter how long you exercise and won’t fall out no matter how much you move.

Features:

• Patented acoustic port design and premium, high-efficiency drivers deliver big sound from a small acoustic package
• Bose's signature Volume-optimized Active EQ automatically boosts the lows and highs so that music, videos, and voices always sound balanced at any listening level.
• New StayHear™ Max tips create a tight seal with your ear canal — critical for hearing the deep low notes that add impact and emotion to your music and for blocking the ambient noise around you
• Comes with three sizes of StayHear™ Max soft silicone tips, so you can find the right fit for you.
• Unique umbrella-shaped tip and the extended flexible wing keep your Bose Sport Earbuds securely in place — without need of an ear hook
• Designed to resist moisture from sweat and weather
• Rated IPX4, which means the electronics inside each earbud are protected against splashing water in case you get caught in the rain on a run.
