New smartphones often no longer feature a traditional headphone jack, instead relying on Bluetooth to connect both devices. If you want to continue using your beloved headphones but your smartphone only has a USB Type-C port, you can opt for the analog Terratec Connect C100: this adapter converts the output into both a classic 3.5 mm headphone jack and a USB Type-C port, allowing you to charge your device while listening to music. This is an analog adapter and does not work with all peripherals. Some smartphones have a digital output, for which this adapter is not suitable.
