Easily use any 3.5mm earphone on a Huawei P20 pro. No noticable change in sound quality but sound level might be slightly lower, note that I'm not an Audiophile or even close. Construction feels sturdy due to braided coverings. Connection fits well on both sides, usb c and 3.5mm side. Length is just enough for an adaptor. Overall It serve that purpose of my purchase. I would definitely recommend considering the price.
