The maximum transmission unit (MTU) is the maximum size of a single data unit that can be transmitted over a digital communications network. Higher-level network protocols, like TCP/IP, can be configured with a maximum packet size, which is a parameter that’s independent of the physical layer MTU over which TCP/IP runs....

However, there is a lot of unneeded information, too. This includes graphs and bar charts that look impressive at a glance, but are overblown and unnecessary.

Sony has taken that aesthetic and that technology and brought it to a product that competes directly (and in my opinion, capably) with the popular Apple AirPods and Airpods Pro....
