Shokz S661
Bone conduction technology paired with an open-ear design delivers situational awareness and a 6-hour battery life, all protected by an IP55 sweat- and water-resistant rating. Its entry-level price undercuts the brand’s premium models while preserving a lightweight titanium frame and universal USB-C charging. This headset is ideal for outdoor runners and cyclists who need to stay alert to their surroundings during training sessions or calls.
