The bone-conduction headphones that let runners and cyclists hear their surroundings while listening to music, creating a safer audio category.
Open-Ear Safety
AfterShokz (rebranded to Shokz in 2022) specialized in bone-conduction headphones that vibrate the cheekbones instead of using earbuds. The Trekz Titanium (July 2016, $129) allowed users to hear ambient sound while listening to music—critical for runners and cyclists avoiding traffic. Sound quality lagged traditional headphones, but safety-conscious athletes embraced them.
Runner and Cyclist Adoption
Marathoners, triathletes, and cyclists made Shokz mainstream. Running forums and subreddits recommended them constantly. The Aeropex (2019, $159) improved audio quality and battery life (8 hours). Military and law enforcement adopted them for communication while maintaining situational awareness. By 2020, Shokz dominated the bone-conduction category they essentially created.
Mainstream Expansion
The OpenRun Pro (2022, $179) added bass via dual transducers, addressing sound quality criticisms. Rebranding from AfterShokz to Shokz signaled mainstream ambitions beyond athletes. By 2023, millions of units sold. While Apple AirPods dominated earbuds overall, Shokz owned the open-ear niche. The company proved bone conduction could be more than novelty—it was essential for safety-conscious active users.
