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.

Manufacturer specification · Listed on the UK page; the US page omits impedance.

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 it brings and what to check

Beyerdynamic DT 900 PRO X

What it brings

  • A 48-ohm nominal impedance and a rated 100 dB SPL at 1 mW mean it is specified for use with laptops, tablets and phones as well as studio interfaces.

  • The single-sided cable detaches at a mini-XLR connector and can be replaced by cables of different lengths and connection options; the ear pads and headband pad are also replaceable.
    Manufacturer source Manufacturer source

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.
