I own a Wh xm4 headphones but seldom use it and dun really like it, plus the ear pad smells and feel sticky when u sweat. With APM, i can just wash the foam ear pads easily and smells great again.I gotta say the XM4 has overall better SQ vs APP1/APP2. But it just doesn't fit my ears. I tried the XM4 with multiple sized spinfit eartips in ConnectIT. It just feels heavy & gonna drop anytime if i start running(It's just me).
But I am a big fan of their WH-1000X series headphone s tho.![]()
