Hello, yes i am looking for a cable with microphone for a smart phone. in german hifi forum I got a tip for this here
I must first wait until the ES-3 for me, if I like I will buy a cable.
I hope the earsonics is better as my westone um pro 20
Almost all upgrade cable manufacturers already offer a mic option. Send them an email to further ask.
I have the UM2 before...and IMO, yes, they are definitely a few steps up in every aspect.
