Do your wired earbuds and headphones with an audio jack no longer fit in your smartphone or tablet? Use a cable converter to listen to your favorite music again. The new iPhone and Samsung models often don't have a round 3.5mm audio jack anymore. Do you have an iPhone (from 7)? Use an Apple Lightning to 3.5mm jack cable converter. Do you have a new Android smartphone, Samsung S, or Note series (since 2020), iPad Pro (since 2017), or iPad Air / Mini? Use a USB-C to 3.5mm jack cable converter. Do you also want to fast charge your smartphone while listening to music? Choose a converter with a Power Delivery charging port.
