Sony Inzone H9 II

Manufacturer: Sony

The Sony Inzone H9 II is a wireless over-ear headset designed for PC and console gaming, offering a blend of flexibility and comfort in a foldable, 260 g chassis. It supports multiple connection methods — 2.4GHz wireless, Bluetooth, and a 3.5mm wired option — making it compatible with PC, PlayStation, Nintendo Switch, and Xbox. Active noise cancellation and an ambient sound mode give users control over how much of their environment they let in, while the tangle-free detachable cable adds everyday convenience.

On the audio side, the Inzone H9 II uses two 30 mm drivers covering the full 20 Hz to 20,000 Hz frequency range and supports both spatial audio and virtual surround sound. Bluetooth LE Audio and AAC codec support round out the wireless audio options, alongside a maximum Bluetooth range of 10 m. The headset includes a removable noise-canceling microphone with a mute function, charges via USB Type-C in 3.5 hours, and delivers up to 30 hours of battery life with a built-in charge level indicator. A travel bag is included in the box.

Cons
  • No aptX, aptX HD, aptX Adaptive, LDAC, or LDHC support limits higher-quality wireless audio codec options
  • Bluetooth range is capped at 10 m, which may be restrictive in larger spaces
  • NFC pairing and fast pairing are not supported, making Bluetooth setup slightly less convenient

  • Only one microphone is included, with no option for a multi-mic setup
Who is this for?

This headset is well-suited to gamers and remote workers who need versatile connectivity across multiple platforms, as it supports PC, PlayStation, Nintendo Switch, and Xbox alongside 2.4GHz wireless, Bluetooth, and wired options. The combination of active noise cancellation, passive noise reduction, and ambient sound mode makes it a solid choice for users working or gaming in noisy environments. Those who move between devices frequently will also benefit from multipoint pairing for two simultaneous connections, and the foldable build with an included travel bag suits users who regularly carry their headset between locations.

Who is this NOT for?

Users who prioritize high-fidelity wireless audio will find this headset limiting, as it lacks support for LDAC, aptX, aptX HD, and aptX Adaptive — codecs commonly sought for lossless or near-lossless Bluetooth transmission. The 10 m Bluetooth range may also frustrate users who need to move freely around a larger space while staying connected. Additionally, those who prefer a quick and seamless Bluetooth setup will notice the absence of NFC pairing and fast pairing, making initial connections slightly more involved.
