Our Verdict

Sony INZONE H9 Wireless

Sony INZONE H9 II

The Sony INZONE H9 II is the successor to the Sony INZONE H9 Wireless. The H9 II has a physical redesign alongside improvements and additions under the hood, including LC3 codec support with Bluetooth LE. The sequel is lighter overall and more comfortable, opting for a more adaptable suspension headband design. The controls on each ear cup have also been marginally improved with a more distinguishable power button shape. Meanwhile, the newer microphone is also better sounding with and without background noise. Both headphones also have a similar sound signature with a heavy mid-bass to low-mid emphasis. If you're a fan of this sound, you'll have to decide whether improvements of the H9 II are worth the extra spend compared to the original H9.
