Our Verdict

Bose SoundSport Free Truly Wireless

AfterShokz Aeropex Bone Conduction

The Bose SoundSport Free Truly Wireless and the AfterShokz Aeropex Bone Conduction are both sports-oriented headphones with different features, so depending on your preferences, you may prefer one over the other. The Bose in-ear headphones are more versatile. They leak less audio, so they're better-suited for uses like office work and have a semi-open design that doesn't block a lot of ambient noise, which is great for people who exercise outside. They also deliver sound more consistently and have a more neutral sound profile, which some listeners may prefer. The AfterShokz, on the other hand, are more comfortable if you don't like the fit of in-ears, have much better controls and block even less external noise than the Bose because they sit outside of your ears. They also have an IP67 rating for dust and water resistance, although we don't currently test it.
