The Sony Float Run are wireless sports headphones with a unique design. Their neckband and ear hooks feature two open-back dynamic drivers positioned slightly away from your ear. It allows for more ambient noise to enter your ear, permitting you to wear them during runs and instances outdoors where it's crucial to maintain spatial awareness. As a result, they struggle to properly reproduce bass, so mixes sound thin and flat. Fortunately, their battery life will last through long workouts and outdoor excursions. They're also rated IPX4 for resistance against water splashes but have slight issues with their build quality.
