Open-Ear Advantage: Safety and Comfort Combined

  • Enhanced Situational Awareness: Runners and cyclists can stay alert to their surroundings, a crucial safety feature.
  • Reduced Hearing Damage: By bypassing the eardrum, bone conduction is gentler on your ears, especially during long listening sessions.
  • All-Day Comfort: No more ear fatigue or discomfort – ideal for extended workouts or swims.

Sound Quality: Balancing Bone Conduction with Bass

Bone conduction technology is known for prioritizing clarity over deep bass. While the Crank delivers crisp highs and mids, bass tones are slightly less pronounced compared to traditional headphones. However, Wildhorn's audio engineers have implemented technological advancements to deliver a richer and more balanced soundscape than many bone conduction headphones on the market.
