(SINGAPORE, May 2017) – Keep the music going on any terrain with the all-new waterproof and dustproof wearable WS623 Walkman®, now with Bluetooth® Wireless Technology. Built to endure extreme outdoor conditions or any sporting activity, the wearable Walkman® is the ultimate sports companion that brings you music without limits.

With improved wearing comfort, the WS623 Walkman® features an ergonomic, slim and light design[1] that stays in place no matter the movement. Newly equipped with Bluetooth® Wireless Technology[2], you now have the option of streaming music from your smartphone using the convenient Near-field Communication (NFC) one-touch pairing, or simply store up to 16GB of audio within.


Love the sea? The WS623 Walkman® is salt waterproof[3], allowing you to swim to a depth of 2 meters with up to 30 minutes of submerged time. Also dustproof[4], it can withstand small particles – making it perfect for any sand based activity or a run along the beach. It also comes with standard earbuds[5] and specially designed waterproof earbuds that are covered with a thin film to prevent water damage to the Walkman® and optimise sound levels for underwater listening. Together with a temperature feature, the Walkman® can endure extreme temperatures from -5°C to 45°C, making it ideal for a hike or climb.


Stay in touch with your surroundings by enabling Ambient Sound Mode, utilising nifty in-built microphones to pick up external voices and sounds in the surrounding environment – allowing you to communicate with your workout buddy or trainer without skipping a beat. A quick charge feature gives a full 60 minutes of audio time with just a three-minute power-up, while a full charge will provide 12 hours of battery life[6].


The WS623 Walkman® will be available at all Sony Stores, Sony Centres and selected Sony authorised dealers from May 2017 at a recommended retail price of S$199.
