I HAD 450BT's but they killed themselves when I accidentally plugged them into my USB-PD charger and just never worked again (probably a shitty firmware update breaking something important which means it just craps itself when it tries negotiating with a USB-PD device. Whatever it is it sucks and I need to get the warranty claim done on it before I forget)
