Our Verdict
Jaybird Freedom 2 Wireless 2017
AfterShokz Trekz Air Bone Conduction
The Jaybird Freedom 2 Wireless 2017 are better and more versatile headphones than the AfterShokz Trekz Air Bone Conduction. The Jaybird are more portable, and since they are closed-back in-ears, they isolate ambient noise and don’t leak much. However, the AfterShokz are designed for runners and cyclists who want to hear what’s going on around them. With their bone-conducting design, the AfterShokz have a better soundstage and act more like background music while you train. They also have better battery life than the Jaybird.
