Sony INZONE H9 II

The exact model is worn over the ears. Closed dynamic construction is stated only for INZONE H9 II in its exact UK specification table; no construction negative is inferred for WH-CH730N.

Approximately 260 g without the detachable microphone. The microphone with windscreen is separately listed at 13 g; the UK product page separately states 273 g with it attached.

The exact model guide expressly states that the headset is not waterproof. This is a documented manufacturer limitation.

Approximately; the exact UK page explicitly states 273 g with the detachable microphone. This is separate from its 260 g without-microphone claim.

Approximately; detachable boom microphone including windscreen, separately from headset and USB transceiver.

Only positively documented audio connections are listed. A charging USB connector is not represented as USB audio. Analogue listening uses the supplied headphone cable. Inserting the analogue cable disables wireless connections.

Manufacturer full-charge maxima for distinct modes. Game-only power saving automatically disables unused calling blocks, but may not activate with every game console or app. Noise cancelling and Ambient Sound have equal limits in these rows. Actual usage varies; the headline 30 hours is not the game-only or analogue maximum.

Built-in lithium-ion batteries are explicitly named. The operating voltage is not converted into a capacity; user replaceability is not inferred.

Approximately; actual charging time varies with conditions of use.

The retained exact-model specification does not establish a battery capacity in mAh. Operating voltage and playback endurance do not establish this quantity.

Wireless charging is not established in the retained exact-model evidence; documented USB charging does not establish absence.

SBC and AAC are positively listed for Classic Audio; LC3 requires compatible LE Audio. Unlisted codecs are not marked unsupported.

A stated version does not establish every optional feature or universal device compatibility.

Approximately; single-sided detachable cable, with CTIA four-pole device connector. No extension or charging-cable length is substituted.

The exact UK specification table names a 30 mm driver unit and carbon-composite diaphragm. No measured sound-quality superiority is inferred.

The exact guide positively names a noise-cancelling headset and documents its active noise-cancelling mode. Presence is not an independently measured attenuation result.

The exact model guide documents voice pickup and call or chat controls; microphone noise filtering does not establish measured attenuation or call quality.

The detachable boom microphone is expressly described as cardioid; no measured pickup pattern is supplied here.

Software functions depend on device, connection and settings. INZONE Hub is for supported PC configuration; it is not available through an analogue-only connection.
