Hi, thanks for your question.
Bose SIE2i sport headphones are designed for use with select Apple products, however, the audio will likely work normally with other smartphones and music players that have a standard 3.5mm output jack. The volume up/down controls will not work with non‐Apple products. The answer/end button may or may not operate properly on an HTC or other brand of phone. (This function varies from model to model.)
