Sony is expected to launch its WH-1000XM5 headphones later this year and a massive new leak seems to reveal some of the key features, specifications and design. The 1000XM5 will succeed the popular WH-1000XM4, widely regarded as one of the best ANC headphones in the market. The headphones have received widespread praise for their Active Noise Cancellation, sound quality, and battery life, but the next-gen model promises to improve on some of those aspects.

Earlier leaks have already revealed a few key details about Sony’s upcoming WH-1000XM5 headphones. The device was listed earlier this year on the official FCC website under the codename ‘Y2954.’ Sketches included with the listing seemed to suggest a sleeker form factor than the existing model, while some rumors also claimed that the headband could be made out of metal rather than plastic. Additionally, an import listing from India suggested that they will be available in the usual silver and black options.

German tech blog TechnikNews claims that one of the biggest improvements to the WH-1000XM5 headphones will be the battery life. Citing an unnamed retail source, the report says that the device will be able to play audio for around 40 hours on a single charge with ANC turned on, possibly making it the best-in-class in terms of battery life. The report adds that the 1000XM5 will take about three and a half hours to fully recharge. This is about half an hour more than the predecessor, but that’s to be expected, given the larger battery.

The report further claims that the 1000XM5 will come with a new driver, although there’s no additional information about that at this point. As for the rest of the hardware, the report claims that the noise cancellation will be taken care of by two processors, while as many as three microphones will be available for audio input. In terms of connectivity, the 1000XM5 will reportedly ship with a 3.5mm socket and Bluetooth 5.2 support. There will also be a USB Type-C port for charging.

TechnikNews also published a series of renders that show off the upcoming device in all its glory. The renders, which are said to be official, seem to confirm the silver and black color options. They also show off a sleeker profile than that of the WH-1000XM4 and reveal more cushioning on the earcups than the current model. The renders also reveal that the the on/off switch is now a slider. As noted by the report, Sony has also seemingly renamed the ‘Custom’ button to ‘NC/Ambient’ even though it’s still positioned at the same spot.
