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.

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.

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

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

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.
Manufacturer source Manufacturer source
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

It is an open-back design (beyerdynamic's operating principle: open) with no active noise cancellation, and neither the product page nor the spec sheet gives an ambient-noise attenuation rating.
Manufacturer source Manufacturer source
There is no microphone or inline remote; the supplied cables are audio-only stereo leads.
