Jaybird topic: Fit Comes First


Pay No Attention To Your Headphones.

Pay No Attention To Your Headphones.

Great fit should be an afterthought—so seamless and free from restrictions that all you experience is the pursuit at hand.

So, as strange as it sounds, our mission is to create the least noticeable in-ear headphones possible. If our products are working as intended, the only thing you should notice about them is your music, because anything else is getting in the way of your athletic potential.

There Is No One Size Fits All.

Like fingerprints, no two ears are exactly alike. We test with as many different people as possible—hundreds of runners, skiers, bikers, climbers, and adventurers around the globe—to create our fit profile.

Our fit data also pulls from tens of thousands of high-tech ear scans—the same ones used for one-of-a-kind custom earpieces—to create a system that optimizes our headphones for intense activity. We want to provide you the comfort, security, and performance of a full-custom earbud without the price or wait time.

Every pair of Jaybird in-ear headphones offers a customizable wearing experience through a combination of overall design and interchangeable fit kits.

The canals and shapes of your ears are not symmetrical, and you shouldn’t be surprised if one ear requires a different size of fin and tip or material to create the perfect fit.  

Perfect is however you define it. You may prefer the added security of a larger fin for high-intensity motion, like plyometrics, or like a smaller tip that allows ambient noise awareness for city running. Adjusting your fit allows you to increase or decrease noise isolation and ease of removal for sports, work, or travel. It’s all up to you.

Over/Under Routing

Why Over/Under Routing Matters.

Interconnected Jaybird headphones feature a streamlined, adjustable cord that joins the buds together behind your neck. You can route the cord over your ears for a more secure, active fit, or under your ears for a looser fit that’s ideal for working, traveling, or simply relaxed listening.
