Images show prototype Sony WF-1000XM4 earphones with new design

The website The Walkmanblog has found new images of what would be a prototype of the WF-1000XM4. These new wireless earphones from Sony have a slightly rounder design than the elongated pill shape of the current WF-1000XM3.

The images from The Walkmanblog show six photos of each earplug. These earplugs are now largely in the shape of a circle, which will probably serve as a touchpad to increase or decrease the volume, for example. At the bottom of this circle is a convex bulge, which has a gold-colored circle on the outside that protrudes from the housing. This gold-shaped ‘button’ may serve as a microphone.

The site also shows images of the charging case. What is striking about this case is that a higher output of 5V=140mA is mentioned. The WF-1000XM3 has an output of 5V=120mA. The current earphones can last for an hour and a half after charging for ten minutes with a fast charging function. The new earphones will probably last longer after the same charging time. Sony may show the earphones at the beginning of June. The site does not say how it got the images, but only says that it concerns ‘prototype images from a PDF document’.
