Can I keep two Bluetooth devices connected to the H9 II at once?
Sony documents a 2.4 GHz game link with one smartphone connected over Bluetooth for chat or calls. That is a mixed USB-transceiver-plus-one-phone arrangement, not two simultaneous Bluetooth connections; it does not meet a phone-and-computer Bluetooth multipoint requirement.
Explore this need in the finder →Can I keep noise cancellation while listening through the supplied 3.5 mm cable?
Yes, with the headset powered on. Sony rates powered cable use with ANC for up to 30 hours. Cable connection disables Bluetooth and the USB transceiver; with power off, the cable can still carry audio but ANC is unavailable.
Explore this need in the finder →Can I keep listening if the H9 II battery is depleted?
Sony documents audio through the supplied headphone cable with the headset powered off. That passive fallback has no active noise cancellation or wireless features, and the headset's own volume controls are inactive in cable mode, so check the source output and volume controls.
Explore this need in the finder →What is the ANC-on runtime for game chat?
Sony's maximum is 20 hours for game plus chat over the USB transceiver with ANC active. The maximum falls to 18 hours when Bluetooth phone calls or music are also active; game-only USB use is listed at 24 hours. These are different modes, not guaranteed personal runtimes.
Explore this need in the finder →This review covers the black US WH-G910NB, not a hands-on gaming or listening test. Sony places the INZONE H9 II in its gaming headset line, but the product is still a closed, circum-aural headphone with documented active noise cancellation, so it belongs in an over-ear ANC comparison. Its game-focused connections make the operating plan more important than a single headline runtime.
One headset, several different wireless paths
Sony's US model page describes both Bluetooth and 2.4 GHz wireless, and the Help Guide spells out what that means: a computer or PS5 can use the USB-C transceiver for game audio and chat, while one smartphone can connect over Bluetooth at the same time for calls or chat. That combination is useful if a phone needs to remain reachable during a game session. It is not two-device Bluetooth multipoint. A phone and laptop connected to two Bluetooth slots is a different feature, and the H9 II does not meet that requirement on the evidence reviewed. The dongle route is also not universal just because the headset is wireless. Sony specifically documents a 2.4 GHz transceiver with a computer or PS5; confirm that the device you use can accept the supplied USB-C receiver and that your console or computer supports the intended game/chat mode. Bluetooth is another route, but it does not provide the same documented game/chat setup. Sony's support specification lists Bluetooth 5.3, classic Bluetooth and LE Audio, with SBC, AAC and LC3. Those are compatibility details, not proof that every host exposes every codec or gaming feature.Wired listening is a real feature, with a power switch attached
Unlike the original INZONE H9 reviewed separately, the H9 II includes a headphone cable. Sony says ANC works in both wired and wireless modes. With the cable connected and the headset powered on, ANC and ambient sound remain available. Sony rates powered cable use at up to 30 hours with ANC active. But the cable disables the USB transceiver and Bluetooth; the headset's volume dial and game/chat balance control are also inactive in cable mode, so volume moves to the connected source. Check that the source has a compatible analog output or adapter before planning around this route. Powering the headset off changes the arrangement again. The supplied cable can continue to carry audio passively, but noise cancellation, ambient mode and wireless functions stop. That makes a useful battery-empty fallback if you only need audio, not a way to keep ANC running without charge. The plug and cable are not a USB audio connection; Sony's documents describe an analog headphone cable. Read the distinction carefully if a laptop or console normally sends audio over USB.Runtime depends on the radio and on what is active
Sony's Help Guide lists up to 24 hours for game-only USB-transceiver use with ANC on, and up to 20 hours when game and chat are both active. Add Bluetooth phone calls or music while gaming and the maximum falls to 18 hours. Powered cable listening is listed at up to 30 hours with ANC active. These figures answer different questions; the largest number is not the runtime for a wireless game-plus-chat session. With ANC off, Sony lists up to 40 hours for game-only use, 30 hours for game and chat, and 48 hours with the cable. The guide also says about five minutes of charging gives roughly an hour of use. All of these are manufacturer maximums for specified modes, not independent measurements or a promise of a particular session length. Call duration, settings, battery age and connection conditions can matter. For a long tournament or commute, plan around the exact mode you will use and leave charging margin rather than relying on the maximum.ANC is available; measured quiet is not established
Sony documents noise canceling and ambient sound, and identifies the headset as closed, circum-aural. That supports a basic feature-level conclusion: ANC is part of the product, and the earcups surround the ears. It does not establish how much noise the H9 II removes for a given wearer. A tight, comfortable seal can affect passive isolation and perceived ANC; hair, glasses, head shape and ear-pad position can all change that seal. Sony's own precautions also warn that the listening environment and fit matter. This review has no microphone-array test, cabin measurement or comparison against the WH-1000XM6, despite Sony's marketing reference to a shared driver unit. For a mixed gaming and everyday routine, ask whether you value ambient awareness or complete quiet more, whether you want the headset's mic and USB receiver to stay set up at a desk, and whether the ear cups clear your ears comfortably. Neither the listed 260 g weight without microphone nor Sony's “lightweight” wording predicts individual comfort; the US product page also gives 273 g with the microphone. The boom mic is detachable and its microphone specification identifies a cardioid pickup pattern. That is a documented design detail, not a voice-clarity score.Package and care checks
Sony lists a detachable boom microphone with windscreen, USB-C transceiver, USB-A-to-USB-C charging cable, headphone cable, soft pouch and printed guides in the box. The inclusion of the USB charging cable does not mean a wall charger is included. Before ordering, confirm the exact WH-G910NB model and package contents, check the host ports for the USB-C gaming receiver, and verify that the analog source accepts the supplied cable. Sony's precautions advise against water exposure; the headset should not be treated as workout or rain gear.Who should shortlist the H9 II?
It is a source-supported fit for someone who wants ANC in a gaming headset, a 2.4 GHz USB-C game/chat link, one Bluetooth phone connection alongside that link, and both powered ANC and passive listening over an included analog cable. It is a weaker fit if you require two simultaneous Bluetooth devices, passive ANC with the headset off, a guaranteed 20-hour-plus runtime with Bluetooth phone audio active, or a universal analog/digital connection without checking the host. Sony's original H9 has a lighter feature set and different port/accessory arrangement; the H9 II's cable and USB-C receiver are meaningful distinctions, not cosmetic updates. This is source-based product analysis, not ownership, testing or a claim about sound, ANC effectiveness, mic quality or comfort. Use the operating modes and exact package checks above to decide whether this gaming-oriented model fits your everyday listening as well as your setup.Key specifications
