Thanks Howdy. To be clear I was thinking isine over cipher v2 not Bluetooth and waiting for a next gen wireless IEM (I still have the sound sport wireless non free and MDR-1000x). I sold my K10u last month. Is the cable issue you mention, all or just BT. Do the isine over v2 cable hold up? Or should I look elsewhere for a good headset to use direct from iphone XS? If so then maybe I will get MTW in meantime.
