Ugreen USB-C to 3.5mm Audio Adapter

A USB-C to headphone-jack adapter with a proper digital-to-analogue converter inside rather than a passive pass-through, which is why it works on phones and laptops that removed the jack entirely. Sound quality is noticeably better than the cheapest adapters, which use minimal converters and hiss audibly. It supports inline microphone and volume controls. Small enough to live permanently on a pair of wired headphones.
