Sony INZONE H9 II Review: Has the manufacturer created one of the best gaming headsets of 2026? This flagship wireless gaming headset combines the acclaimed drivers from the WH-1000XM6 (review), active noise cancellation, and dual connectivity via 2.4 GHz wireless and Bluetooth. After the first INZONE H9 (review) proved solid but not entirely convincing, Sony is taking a second shot with this successor. The result is a headset that, weighing just 260 grams, ranks among the lightest in its class while also aiming to be an all-around performer for gaming, music, and on-the-go use. Our review will determine whether it succeeds in this balancing act and whether the steep price tag is justified.

Sony INZONE H9 II Review: Design and Build Quality
Visually, Sony stays true to itself and keeps the INZONE line deliberately understated. The large, round ear cups are clearly reminiscent of the predecessor, but appear cleaner and more modern. The headset is available in either black or white, though the white version, with its soft curves, looks more like a lifestyle headset than a classic gaming accessory. If you remove the microphone arm, you can easily wear the INZONE H9 II on the train or in a café without drawing attention to yourself.
The real highlight when you hold them is their weight. Weighing in at around 260 grams (without the microphone), the H9 II is one of the absolute lightweights among fully-featured wireless headsets. This is made possible by a newly designed headband: A thin steel frame is wrapped in fabric, beneath which sits a separately mounted, padded synthetic leather strap that rests directly on the head and distributes the pressure. The result is a fit that remains stable without creating uncomfortable pressure points on the top of the head. In my opinion, the comfort is excellent.
The ear cushions are generously sized and covered with a dense mesh fabric that strikes an amazingly good balance between sound isolation and ventilation. You get the passive isolation of closed-back headphones without your ears getting sweaty after a short time—and the balanced clamping force is comfortable even for glasses wearers. The ear cups can be rotated flat in both directions, making it convenient to drape them around your neck. However, the headset cannot be folded up.
There are a few minor issues with the build quality. Although the housing is mostly made of ABS plastic—which at first glance seems a bit cheap—that impression is misleading: nothing creaks, the gaps are precise, and the components give the impression of durability on par with Sony’s audiophile flagship models. The only recurring criticism in practice is the somewhat thin padding on the headband, which can cause slight pressure on the crown of the head for some users after one to two hours. A quick adjustment usually solves the problem.
What I really don’t like, however, is how loose the ear cups are. While they can be swiveled (and even in both directions), they feel very wobbly and don’t stay in place. This doesn’t bother me when wearing them, but they feel a bit cheap when held in your hand.
Package Contents and Features
When it comes to accessories, Sony gets a lot right and even includes items that are often missing from more expensive competitors. In addition to the headset, the box contains:
- a detachable boom microphone with a windscreen (connected via a 3.5-mm jack on the left ear cup)
- USB-C 2.4 GHz wireless dongle
- USB-C-to-USB-A charging cable (approx. 1.8 m)
- 3.5-mm analog audio cable (approx. 1.8 m)
- soft carrying case with additional compartment
- Documentation, warranty information, and INZONE sticker
A particularly nice touch is the included carrying case with a separate zippered compartment for cables and the dongle. For a headset that’s explicitly designed as a travel companion, this is exactly the right addition.
An important consideration before purchasing is platform compatibility. Via the USB-C dongle, the INZONE H9 II works with PCs, PS5, compatible handhelds, and other devices with a USB-C port. On older PCs, a USB-A adapter may be required, depending on the connection. The Xbox is not supported: It can only be connected to the controller via the analog 3.5-mm jack cable, meaning that ANC and wireless features are not available on the Xbox. Anyone who primarily plays on the Xbox should consider this carefully.
Controls and Connectivity
Sony has thoughtfully distributed the controls across both ear cups, spacing them far enough apart that you won’t accidentally press the wrong button even when operating the headset by feel. On the right side are the two buttons for game/chat balance, the power button, and the Bluetooth pairing button. On the left, you’ll find a switch that toggles between ANC, Ambient Mode, and normal operation, a volume wheel, the USB-C charging port, and the microphone jack. The large mute button is located at the top of the left ear cup, making it accessible in a flash. The volume wheel has enough resistance to prevent accidental adjustments.
The Sony INZONE H9 II really shines in terms of connectivity, thanks to its dual-connection feature. For gaming, you use the included 2.4 GHz USB-C dongle, which provides a virtually latency-free wireless connection. At the same time, the headset can be paired with a smartphone via Bluetooth 5.3, allowing you to answer calls or listen to music while gaming without disconnecting from the console. This simultaneous use of wireless and Bluetooth is invaluable in everyday life.
On the Bluetooth side, the headset supports SBC, AAC, and LC3 as part of LE Audio, which ensures longer battery life and better sound quality, as well as Auracast Broadcast streaming. While classic multipoint (i.e., two simultaneous Bluetooth devices) is missing, this is largely compensated for in practice by the parallel use of the dongle and Bluetooth. In addition, there’s an analog 3.5-mm connection—handy for handheld devices, Xbox controllers, or as a workaround when the battery is dead.
Battery Life of the Sony INZONE H9 II
When it comes to battery life, you have to look a little closer. Sony officially claims up to 30 hours—but that’s without ANC enabled. If you’re gaming with noise cancellation enabled via the 2.4-GHz wireless connection and at medium volume, you’ll typically get around 19 hours in practice. That’s okay, but compared to other high-end headsets—some of which last 40 hours or more—it’s not top-tier performance.
A Glorious GHS Wireless InfinitePlay (review) lasts significantly longer at 85 hours, while the similarly equipped SteelSeries Arctis Nova Pro Omni (review) offers a similar battery life. Precisely because the H9 II aims to be an all-around performer even on the go, you’ll need to plug it in a bit more often than with some competitors.
At least the fast-charging feature makes this a much less of an issue: According to our tests, five minutes on a USB-C cable restores about three hours of playtime, while a full charge takes about 3.5 hours. It’s also convenient that you can continue using the headset as usual while it’s charging. If you make a point of giving it a quick charge every evening, you’ll hardly find the average battery life to be an issue in everyday use.
App Connectivity via INZONE Hub and Sound Connect
Software connectivity is handled in two ways. On a PC, there’s the INZONE Hub; on mobile devices, there’s the Sony Sound Connect app for iOS and Android. Both offer largely the same range of features, so the choice is primarily a matter of personal preference. The Hub features a clean, organized interface and consolidates all relevant settings in one place.
At its core is the equalizer, which includes several FPS-specific presets as well as a customizable 10-band EQ. It also includes controls for ANC and Ambient Mode, microphone settings, sidetone (i.e., feedback of your own voice), and virtual surround sound, which positions sounds within a 3D soundstage. While it lacks a true parametric EQ with freely selectable frequencies, the feature set is solid for a gaming headset.
A particularly clever feature: EQ profiles can be saved directly in the headset. This allows you to use your preferred sound settings on the console as well, without having to run PC software in the background. This makes the INZONE H9 II significantly more flexible across platforms than many competitors, whose EQ only works when desktop software is active.
Focus on Active Noise Cancellation
ANC is still a rarity in gaming headsets, although more and more manufacturers are jumping on the bandwagon. Audeze already impressively demonstrated the benefits of this for gaming with the Maxwell 2 ANC (review): Anyone playing in a noisy environment benefits from being able to block out distracting background noise. Since Sony is one of the leading manufacturers of ANC headphones in the WH-1000 series, expectations are correspondingly high—and the INZONE H9 II largely meets them.
The system reliably filters out monotonous, continuous noises such as PC fans, air conditioners, or street noise, creating noticeably more peace and quiet and allowing for better concentration while gaming. Combined with the already robust passive noise isolation provided by the closed-back design, the typical background noise of a home office or gaming room is significantly pushed into the background. As expected, the system doesn’t quite measure up to the absolute top tier of pure lifestyle ANC headphones, such as the Sony WH-1000XM6, when it comes to voices and high frequencies. Keyboard clicks and speech are muffled but not completely eliminated. For a wireless gaming headset, however, the performance is absolutely impressive.
Two additional points stand out positively: First, the sound signature remains virtually unchanged with ANC activated. This is precisely where many competitors fall short, sounding thin or artificial when noise cancellation is turned on. Second, the ANC doesn’t create any unpleasant pressure on the ears, and in silence, only a very faint background hiss is audible. One real drawback remains: the H9 II doesn’t offer a full-fledged transparency mode that lets outside sounds through as naturally as possible. While there is an Ambient Mode that lets in more ambient noise, it doesn’t come close to the natural sound quality of specialized headphones.
Audio Quality, Spatial Sound, and Microphone
The most exciting aspect is the sound, as Sony uses the same 30-mm carbon-fiber composite driver unit here as in the highly acclaimed WH-1000XM6. However, anyone who automatically assumes this means audiophile-level music enjoyment will need to adjust their expectations: The Sony INZONE H9 II is first and foremost a gaming headset, developed in collaboration with the esports team Fnatic, and you can hear that in the tuning.
The sound is deliberately tuned to be understated right out of the box. But honestly: I really like that! It’s not that typical bass-heavy sound found in many gaming headsets. The deep bass is subdued, and the highs are slightly rolled off, so nothing overpowers the soundstage. For music and movies, this initially feels a bit cold, and the midrange lacks a bit of warmth and precision. For competitive gaming, however, this tuning is ideal: footsteps, reloading sounds, and directional cues stand out clearly without being drowned out by boomy bass. In games like Counter-Strike 2, Valorant, or Overwatch 2, you can pinpoint enemies with great precision; the stereo image is cleanly layered and wide. Explosions sound crisp and controlled rather than overwhelming.
The good news: You can significantly enhance the sound profile using the EQ in the INZONE Hub or app. If you tweak a few settings for music, you’ll get a thoroughly pleasant, balanced sound—one that, while it doesn’t replace dedicated hi-fi headphones, reaches a high standard for a gaming headset. The virtual surround sound credibly rounds out the immersive experience in single-player and story-driven games. The bottom line is this: As a gaming headset, the H9 II is among the very best; as a dedicated music and multimedia headset, however, there are better alternatives available for the same price.
Good Microphone with AI Filter
The detachable, highly flexible boom microphone with a windscreen features a cardioid pickup pattern and AI-powered noise cancellation. In our test, it impressed with clear, intelligible, and interference-free voice transmission—background noise such as keyboard clacking is reliably filtered out, and the volume remains pleasantly consistent, without the dropouts or level fluctuations typical of wireless mics. It’s more than sufficient for in-game chat, Discord, and even video calls while working from home.
There are some minor trade-offs in the details: the voice tends to sound slightly muffled, plosive sounds occasionally come through a tad too harshly, and the microphone’s sound itself cannot be fine-tuned via EQ. What you hear out of the box is the final result. It’s also noticeable that the voice quality on the PS5 sounds audibly thinner than on the PC.

For serious streaming or recording, a dedicated USB or XLR microphone remains the better choice—but for everyday use at your desk, the headband mic does a really good job.
Sony INZONE H9 II Review: Conclusion
The Sony INZONE H9 II is an all-around excellent premium wireless headset that clearly defines its priorities. Its greatest strength is the combination of light weight, high comfort, and flexible dual connectivity: Weighing in at around 260 grams, it practically disappears on your head, and thanks to simultaneous operation via 2.4 GHz wireless and Bluetooth, it becomes a true all-rounder for consoles, PCs, and on the go. Add to that the high-quality WH-1000XM6 drivers, ANC that’s very impressive for a gaming headset without compromising sound quality, and a microphone that delivers clear, intelligible audio.
Still, the headset isn’t perfect. The factory settings are heavily geared toward competitive gaming and only sound truly balanced for music after EQ adjustments; the microphone performs poorly on the PS5; a full-fledged transparency mode is missing; and the battery life with ANC is only average at around 19 hours. The price also takes some getting used to—at a MSRP of 349 euros, the H9 II is an expensive purchase, even though the street price is now significantly lower.
The bottom line is that the INZONE H9 II is aimed at a clearly defined target audience: ambitious gamers looking for a lightweight, highly comfortable wireless headset with top-notch spatial audio, good ANC, and maximum platform flexibility. Those who primarily listen to music or need an Xbox-compatible wireless headset will find more suitable alternatives. For everyone else, the H9 II is one of the best wireless gaming headsets in its class.
