Sony – LinkBuds open style wireless earphone

Bose Sport Earbuds make your music sound like the performer is right there beside you, pushing you to go one more mile or do one more rep. Our patented acoustic port design and premium, high-efficiency drivers combine to deliver big sound from a small acoustic package. Our signature Volume-optimized Active EQ automatically boosts the lows and highs so that music, videos, and voices always sound balanced at any listening level. And our 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 so you can focus on your music and your workout.
