The Sony NW-WS413 is a 4GB MP3 player built into a set of waterproof and dust-proof IP67/68 headphones.
There’s also the NW-WS414, which are identical but bump up the storage to 8GB. Both models form part of the Sony Walkman NW-WS410 series.
This generation of waterproof MP3 players offers better battery life than before, as well as fast-charging capabilities
To say that the Sony Walkman NW-WS413 headphones are comfortable and a good fit would be an understatement.
While they might look bulkier than your usual in-ears, they certainly don’t feel it. They’re light and well fitted so that whether you’re running or swimming they sit perfectly in place throughout.
