THE DIFFERENCES, MADE VISIBLE

Visual facts

Differences first. Select a topic for its graphic, sources and conditions.

How to read this comparison
  • Manufacturer facts for the exact models shown. Not a quality rating or a test result.
  • “Different” means the known values differ, not that one is better.
  • Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.
FEATURES SIDE BY SIDE7 topics

Yes and No describe the listed feature. Missing evidence stays unverified.

SELECTED TOPIC

Impedance

Nominal electrical load, not sound quality or loudness. Output capability and headphone sensitivity matter together; impedance alone cannot decide whether an amplifier is needed.

HyperX Cloud Alpha Wireless62 Ω

Explore the full specifications

Start with your listening environment. Open and closed earcups suit different surroundings. A closed back is not the same as active noise cancellation. Check the exact cable and headphone output. We do not turn impedance, driver size or unpaired lab results into a sound-quality score.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

HyperX Cloud Alpha Wireless

What it brings

  • HyperX rates the battery at up to 300 hours (tested at 50% headphone volume), with a full charge taking about 4.5 hours according to the US page.
    Manufacturer source Manufacturer source
  • The detachable microphone has an LED status indicator, and HyperX lists a wireless range of up to 20 m.
    Manufacturer source

What to check

  • The specification summary names PC, while a feature bullet claims multi-platform compatibility without naming platforms. The documented audio connection uses the 2.4 GHz USB adapter; other input support is not explicitly established.
    Manufacturer source Manufacturer source
  • The manufacturer’s “noise-cancelling” description applies to the microphone. The reviewed exact sources do not explicitly establish active noise cancellation for listening.
    Manufacturer source Manufacturer source

Sennheiser HD 300 PRO

What it brings

  • Sennheiser rates up to 32 dB of passive ambient-noise attenuation from the closed back and viscoelastic ear pads, for loud environments such as stages and broadcast.
    Manufacturer source Manufacturer source
  • Ear pads, headband padding and the cable are described as field-replaceable by the user.
    Manufacturer source Manufacturer source
  • Impedance (64 Ω), sensitivity (108 ±3 dB SPL at 1 V) and maximum SPL (123 dB) are all published, which helps when matching it to a mixer or headphone amplifier.
    Manufacturer source

What to check

  • Sennheiser rates the contact pressure at approx. 6 N for a secure fit, and at approx. 297 g without the cable, comfort over long sessions is personal.
    Manufacturer source Manufacturer source
  • Check the supplied cable configuration: Sennheiser describes a coiled section near the earpiece, lists a 1.5 m cable in the box and approx. 1.55 m in the technical data. The separately listed straight cable is a replacement option. The transducer diameter is not stated.
    Manufacturer source Manufacturer source
  • The specification sheet lists this HD 300 PRO configuration without ActiveGard. Switchable ActiveGard hearing protection belongs to the separate HD 300 PROtect, article 506898; it is distinct from the unresolved active noise-cancellation claim.
