The question is whether the mic works. If it does then the headset is probably CTIA (if it would be OMTP the mic wouldn’t work). If the mic works then your question is about the buttons on the remote - which judging by other posts on the forum can be tricky to get right. There are some apps that are occasionally recommended to map the buttons to a specific function - I can’t specifically recommend any (no experience) try searching around a little for recommendations (though I do note there appears to be a philips specific one that offers button customisation - but maybe only for 1 button models - and audio ‘enhancements’).
