The in20 is the latest in-ear headphone in our award-winning thinksound line. It combines the best of everything in a small package with big sound. It’s our most versatile headphone yet and is engineered to have a smooth sound signature via upgraded acoustics so you can listen for hours on end.  

The gunmetal aluminum baffle is mated to a hand-crafted, sustainable walnut housing to give it that distinctive thinksound character. Passive noise cancellation minimizes ambient sounds and there’s a high definition in-line mic for clear communication. We’ve retained the corded design to ensure a consistent and reliable connection, which is a necessity in today’s world of virtual meetings.
