22 specifications in 6 groups. Values are manufacturer specifications unless a row says “Measured result” or “Calculated from cited specifications”.
HyperX does not state whether the microphone is included. The US page lists 0.7 lb.
HyperX lists no Bluetooth and no analogue input; the supplied cable is described as a charge cable.
HyperX's test condition: 50% headphone volume. The charge time appears on the US page only. Manufacturer footnote [2] describes a fully charged headset plugged via USB to a system, with system and media-player volume at 50%; it does not clearly identify whether that USB wording refers to the headset or its wireless adapter. Retain the rated battery claim, but the exact test connection remains unresolved.
HyperX notes range may vary with environmental conditions.
SourceHyperX's UK and US pages list 'Compatibility: PC' in the specification summary, but the same pages' key-feature list advertises 'Multi-platform compatibility' without naming the platforms. Check the listing for console or mobile support.
