    Thank you for your inquiry. It is made to answer calls.


    It works on Samsung Galaxy S4 ?


    Yes they do!


    Can they be used for online gaming on the ps4??


    Any Audio-Technica ear-bud/headset that features a single "i" at the end of the title are MFi, or "Made For iPhone". It might not be an ideal choice to use with PS4 because of that. However, any Audio-Technica headphone that features an "iS" at the end of the title feature a should work, such as the ATH-CKX7iS. Also, if you are to use any third-party ear-buds/headsets from any manufacturer with PS4, you might not have full functionality of the ear-bud's controller. If you have any further questions or for any correspondence, please include your original question and this response, and contact the Audio-Technica United States (ATUS) Audio Solutions Team at: Thanks!
