FAQ
Q: Will a USB-C to 3.5mm adapter work with any USB-C phone or laptop? A: Most do, but some devices handle the analogue conversion differently, so it is worth confirming your specific phone or laptop is supported before you buy.
Q: Does the adapter affect sound quality? A: A good adapter passes a clean signal to your headphones; for everyday listening any of these picks should sound clear and consistent.
Q: Can I charge my device while using one of these adapters? A: These are headphone-only adapters with no charging port, so if you need to charge and listen at the same time you will want a combo adapter that adds a separate USB-C power input.
