Some companies like Westone, also make a replacement bluetooth cable since their IEMs all have replaceable cables. https://www.amazon.com/Westone-MMCX-Bluetooth-Cable-78548/dp/B01H3XS2ZQ https://www.amazon.com/Westone-MMCX-Bluetooth-Cable-78548/dp... I am pretty sure the correct answer is: Stop making phones so thing and bring back the 3.5 headphone jack. If the 3.5 really is a hindrance, come up with a connector that allows a simple adaptor to 3.5 jacks and still allows cabled charging. I already have a couple of L-adaptors for my headphones with straight connectors, so carrying a 3.5-to-Lightning doesn't bother me. But not being able to charge at the same time. WTF? iPhone SE forever!
