What they are

No Sew USB-C wired over-ear headphones with a 40 mm dynamic driver, 32 ohm impedance and inline volume control. The foldable frame weighs 0.25 kg and connects through a digital USB-C port on compatible laptops, computers and recent phones. Built-in microphone supports calls and voice pickup for everyday use.

Who they suit

Buyers wanting a single-cable headset for stereo listening, online classes or conference calls on devices that accept USB-C digital audio. Not for gamers who need real-time chat while playing, nor for owners of older USB-C ports that lack digital audio support. Wireless users and anyone requiring active noise cancellation should look elsewhere.

Deciding specification

The headphones use the USB-C Digital Audio standard, so they only work on hosts that implement that protocol. If your device does not support USB-C digital audio, the headset will not function regardless of its 40 mm driver or 32 ohm rating.

Questions about this item

Should I pick the 32 ohm version or look for a different impedance?

The headphones have a fixed 32 ohm input impedance; there is no alternative version to choose.

What does the 40 mm driver mean for everyday sound?

The 40 mm dynamic driver delivers stereo sound across a 5 Hz to 20 KHz range for music, calls and media.

Does the USB-C connector limit volume or audio quality on my laptop?

The USB-C digital audio connection powers the headphones directly; some older or entry-level USB-C ports may not support this standard.
