Instead of wearing headphones all day while working from home, Sony is proposing wearing a speaker around your neck.
NB10 Sound and Features
The speaker fits around collared shirts and sweatshirts. I also didn't notice any audible rustling sounds caused by clothing, and no one complained about static noise. The microphones are on the top right side and should remain out of the way. I'm not sure how the device would fare during a summer heatwave and whether it would cause sweating, but in general, it becomes invisible to the wearer under normal home use.
On the bright side, there is some stereo separation between the left and right. Plus, because of the proximity from the device to my ears, the sound is certainly listenable. But given the chance to use any small speaker, I would much rather do so on a HomePod mini or Sonos Roam. Both of those could also be used for conference calls, but the HomePod mini can't travel from room to room.So, the NB10 is not an ideal music speaker.
