[Direct from Japan] Sony NW - WS414 Walkman 8GB Headphone-In …, Mandai

Product Description
A Walkman with integrated headphones, eliminating the hassle of cables during sports. Enjoy comfortable music even while running, swimming, or engaging in other athletic activities.
Weighing approximately 32g, it's incredibly lightweight for sports. The neckband design securely stabilizes the Walkman on your head and is optimized for water resistance. The seamless, rounded earpiece further enhances the fit. It stays securely in place during running, swimming, and other sports activities, ensuring comfortable use without worrying about it slipping or falling out.
The included adjustment band allows for secure fastening even if there's some space between the neckband and your head. It resists shifting even during vigorous movement and provides a secure fit for those with smaller or narrower heads.
In addition to high water resistance equivalent to JIS IPX5/8, it also features saltwater resistance and JIS IP6X dustproof protection. Enjoy your favorite music while running in the rain, swimming in a pool, or at the beach.

Featuring terminals resistant to corrosion and less prone to foreign matter accumulation, and a stain-resistant coating on the main body surface, these headphones are compatible with fresh water, pool water, and even seawater (saltwater). Furthermore, a unique sealing structure that equalizes the compression rate of the annular gasket ensures dustproof performance in various usage environments, allowing for comfortable use at the beach or in the sea.

Using silicone material that resists hardening even at low temperatures, and employing a battery protection system for high temperatures, these headphones offer excellent cold and heat resistance, from -5°C to 45°C. Enjoy them in a variety of situations, including running in cold climates, winter sports, and even in the bathroom.

The design prevents water from entering the headphone section, providing higher waterproofing than standard ear tips, allowing for more comfortable music enjoyment while swimming.

The waterproof design also allows for washing. Sweat and dust can be easily washed away, ensuring a clean and pleasant user experience.

Equipped with an "ambient sound capture function" that uses built-in microphones in both headphones to pick up surrounding sounds such as car noises and people's voices and mix them into the music. This allows you to be aware of your surroundings during sports and communicate with those around you. It features a mode for enjoying music directly and a mode that allows you to adjust the ambient sound volume in three stages.

It automatically charges when connected to a PC using the included USB cradle. A full charge provides up to approximately 12 hours of playback. This ensures ample stamina for full marathons and long training sessions.

A quick 3-minute charge provides approximately 60 minutes of playback. It's convenient to quickly charge it before running and take it with you.
