The Questyle Qlink-C is a 5g USB-C to 3.5mm DAC dongle built on the Conexant CX31993, with playback up to 32-bit/384kHz, 28mW into 32Ω and a 100dB signal-to-noise ratio. It suits anyone who wants to plug wired earphones into a jack-less phone, tablet or laptop.
Who the Questyle Qlink-C is for
Phones without a headphone jack: It is plug-and-play with no drivers on USB-C iPhones and iPads, Android phones, Macs and Windows PCs, so wired earphones work again on jack-less devices.
Everyday IEMs and earbuds: The Conexant CX31993 plays up to 32-bit/384kHz and puts out 28mW into 32Ω with a 100dB signal-to-noise ratio.
Calls on the go: Questyle says headset microphones and inline controls for volume and play/pause keep working through the adapter.
Laptops and desktops: A USB-C (female) to USB-A (male) adapter comes in the box for computers with older USB-A ports.
Skip it if: you need a 4.4mm balanced jack or more power for full-size headphones — it has one 3.5mm output rated 28mW at 32Ω, and its USB-C plug does not fit Lightning iPhones.
