Our take on the Sudio K3 Pro Headphones

The Sudio K3 Pro is an over-ear headphone with 40 mm drivers, active noise cancelling and a built-in microphone, wired rather than wireless. The wired connection means no charging and no Bluetooth pairing, which suits desk, studio and travel use where a cable is acceptable. Against wireless rivals like the Sony WH-1000XM5 or Bose QuietComfort, it gives up cable-free convenience but keeps ANC and an over-ear fit. Buyers who want a simple plug-in ANC headphone with a water-resistant build are the target; those who need untethered listening should look elsewhere.

Pros
  • Active noise cancelling cuts steady background noise
  • No battery to charge or Bluetooth to pair
  • 40 mm drivers give a full-size over-ear sound
  • Built-in microphone for calls
  • Water-resistant build handles light rain and sweat
Cons
  • Wired only, so no cable-free use with a phone
  • No battery means ANC needs power from the source device
  • 32 ohm impedance is easy to drive but not aimed at high-end amps
  • Fewer features than wireless rivals at the same tier
