Sony WH-1000XM4C leak suggests Bluetooth 6 upgrade, but fewer extras in the box
Sony appears to be preparing a refreshed version of its popular WH-1000XM4 over-ear wireless headphones, reportedly called the Sony WH-1000XM4C. While the design seems familiar, the updated model may bring a few notable changes that could affect buyers looking for premium noise-cancelling headphones.
One of the biggest reported upgrades is wireless connectivity. The WH-1000XM4C is expected to replace the older Bluetooth 5.3 modem with a newer Bluetooth 6-capable option. If accurate, this could improve connection stability, efficiency, and overall wireless performance, depending on device support.
However, not every feature appears to be making the jump. The absence of NFC branding suggests that Sony may remove NFC quick pairing support from the WH-1000XM4C. That means users might need to connect through standard Bluetooth pairing instead of tapping a phone to the headphones for instant setup.
The leak also suggests Sony may simplify the retail package. Instead of including a matching premium carrying case and accessories, the WH-1000XM4C could ship with a basic grey case and standard cables. This may point to a cost-conscious refresh rather than a full next-generation release.
In terms of hardware, the headphones are still expected to include a 3.5 mm audio jack and a USB Type-C port, giving users both wired and modern charging options. The familiar 40 mm dynamic drivers are also rumored to return, which means the sound profile may remain close to the original WH-1000XM4.
Battery life could be one area where the new model takes a small step back. Reports suggest the WH-1000XM4C may offer around 10% shorter battery life when active noise cancellation is turned on. For frequent travelers or long listening sessions, that detail may be worth watching closely.
Overall, the Sony WH-1000XM4C looks like a modest refresh of a well-known pair of wireless noise-cancelling headphones. With Bluetooth 6 support, USB-C, a 3.5 mm jack, and proven 40 mm drivers, it could still be a strong option for listeners who want reliable audio and ANC. But the possible removal of NFC pairing, fewer bundled accessories, and reduced ANC battery life may make it feel less premium than expected.
