Hi @audiophile88 

That’s great, thanks - I’ve passed it along to my colleague for him to examine. I’ll let you know what comes of it.

Hello !
I didn’t update my Sonos Ace since i bought it at launch (begining of june) in France. I use it in a work space environment with many people talking around me. After the update, i observe that the active noise reduction seems clearly less effective for canceling human voice. Is it on purpose ? I’m currently running on the 2.9.5 firmware.

Hi @Lofn 

I am not aware of any changes made to Active Noise Cancellation on Sonos Ace headphones since their launch.

I can confirm the recent update did fix the USB-C PD Charging issue. Was on the road this weekend and plugged my set in to charge overnight. Woke up and it didn’t work. Downloaded the update, plugged it in and the orange charging light appeared immediately.
