Oneplus ctype to 3.5mm adapter??? No they do not work. You will need a ear phone with ctype cable or buy a sound card. You can also buy a costly fan accessory from asus to get a 3.5mm port if you want.
I have one of those and only charging works, the sound doesnt come from the 3.5mm. tried everything and only sound card works for me out of all. You can buy the fan accessory or sound card or a headphone with ctype built in. I hope i could help.
