The images show the Sony WF-1000XM5 as the most compact of the three, while the Sony WF-1000XM4 appears to be the tallest. The purported WF-1000XM6, meanwhile, looks thicker than the WF-1000XM4 and taller than the WF-1000XM5, suggesting it could sit further out of the ear than earlier generations. Sony has not confirmed these details and has not revealed if the updated design will affect comfort or fit.
A new leak from tipster Roland Quandt on Bluesky suggests that Sony plans to introduce the WF-1000XM6 in a third colour option called "Sandpink". This would mark a change from Sony's usual launch strategy for its premium earbuds. The Sony WF-1000XM5 debuted in 2023 with only Black and Platinum Silver colour options. The company later expanded the lineup in 2024 with a Smoky Pink variant.
