Binatone's MaskFone is a $50 (42 euros) washable mask that features Bluetooth headphones and a microphone.

Whether we like it or not, masks have been a part of our daily lives for quite some time now and will remain so until the COVID-19 pandemic ends. At CES 2021, many gadgets and products related to the use of masks for COVID-19.
A good example is Binatone's MaskFone mask. The MaskFone is a washable N95 mask with a Bluetooth headset and microphone built into it, allowing you to talk to people on the phone without your voice being distorted by the mask. The mask costs $50 (42 euros).
The headphones connect with a cable clip that hooks around your ears, and there are buttons for play/pause and volume control on the mask itself. The MaskFone also features Siri and Alexa, so you can listen to music by giving the command through your voice assistants. The MaskFone is also supported by the Hubble Connect app, offering clear, interruption-free sound.
Binatone says the headphones last for 12 hours, so that means you'll need to charge your MaskFone if you want to use its full range of features .

It's one of several devices unveiled at CES aimed at making our lives easier during the COVID-19 pandemic. LG showed off its lineup of air purifiers, which included a battery-powered mask with a purifier inside, as well as a portable PuriCare Mini purifier that you can take with you on the go. Existing products have also been updated, like LG's new InstaView refrigerator that opens with voice command and disinfects water with UV rays.
