Hi there! Thank you for requesting clarification as to how the Bluetooth Galaxy Watch Active Smartwatch (40mm) will work for enjoying your music. Regarding the ability to listen to the music through the headphones (Bluetooth) or earbuds, you would have to ensure that your Smartwatch/Wearable stays within range of the mobile device to ensure the connection between the Bluetooth and the mobile device is solid allowing the Bluetooth headphones or earbuds to remain connected for full enjoyment of your music selection(s). You, also, have the option to store music within the Smartwatch. You can find all the details using this link (https://bit.ly/2X08YR6) and starting within the e-manual at page thirty-seven (37). Thank you for taking the time to validate the information and for choosing Samsung! ^Liz
