Mangetic Earbuds - NW20
There are magnets on the back of the earbuds that allow them to stick together so that they don't dangle around and stay nice and neat.
Ergonomic Neckband Design - NW20
The neckband design has been improved with comfort in mind. The neckband is shaped specially to fit the curve of the neck to provide better comfort.
Improved Wire Connection - NW20
The wire is housed in the middle of the neckband, compared to the NW10 where the wire is coming from the end. This makes the wire shorter, easier to manage, and more durable.
