Headphones you charge about once a month? Welcome to Tech After Dark, I'm Nova, here with Hopper, and Panasonic just launched a pair with a 100-hour battery life. They're the R B-HJ800, just announced in Japan. But hold on, Nova, that 100 hours is with noise cancelling switched off. Of course it is. Turn it on and Panasonic says about 72 hours, which is still nearly a month of listening at two and a half hours a day.

And it's 14,850 yen in Panasonic's Japanese online store. Fun part? The product page says November 18th, but the store says the 19th. Can't even agree on the day. International pricing isn't confirmed yet. Thanks to Notebookcheck, the full post is linked. See you next time!
