A:AnswerYes, you can use Shokz OpenFit earbuds with just one earbud at a time. Both earbuds can function independently, and you can use either the left or right earbud.
A:AnswerHello-Shokz here! DirectPitch™ technology keeps the listening experience for you alone as you enjoy awareness of any situation. They should not be able to hear your music. Please reach out to our Customer Happiness Team if you have any other questions. Thanks!
