A:Answer Our JBL Endurance Peak has Bluetooth capability and can pair with most devices such as phones, tablets, and laptops. Please check the volume of the source you're playing or adjust it using the touchpad. To increase the volume, move your finger up the ridges above the JBL logo on the RIGHT earbud. To decrease, move your finger down along the ridges. If you need more help, please reach out to our Customer Support. https://support.jbl.com/us/en/
