Sony has released their first firmware update for the new WF-1000XM4. The version is now 1.1.5 and this update improves Bluetooth connection stability. Reading some reddit posts, it looks like some people have issues installing the firmware but I suspect this might be down to the earbuds powering down and the install failing.
Looks like Sony will have another wireless headset this year to complement the WF-1000XM4 and YY2952. Unknown what this is, could be a low end device, as it is made in Vietnam (see update).
Sony Group Corporation and Sony Corporation have developed "Original Blended Material," an environmentally conscious and sustainable paper material made from bamboo, sugar cane fiber and post-consumer recycled paper, whose origins are specified.
After many leaks, Sony has finally announced the new WF-1000MX4. Most of the details leaked, so rather than post the press release and specs again, I will go over some of the new things for me.
Another day, another retail listing. This will probably be removed shortly but I have gathered all the information from it. The listing provides two new details, the driver size, still 6mm unfortunately and that Speak-to-Chat uses Sony's Precise Voice Pickup technology which uses 4 microphones for better voice quality.
