On February 28, 2023, SONY held the SONY Audio Product Launch and Unbox Experience Event, where it officially announced three new headphones, including Float Run, a non-in-ear open sports headset for comfort, and two cost-effective headsets -- WH-CH720N, the lightest wireless noise cancellation headset in SONY's history. And the WH-CH520, featuring a colorful Morandi palette with a sense of style and quality.

With the promotion of public health awareness, more and more people are incorporating exercise and fitness into their daily life. Based on users' insight into the need for sports headphones to be "comfortable, firm and sound" and healthy with their ears, SONY has created and launched Float Run, a sports headset designed for comfort. Weighing only about 33 grams and with a delicate ear and head support design, Float Run makes wearers' headphones feel as light as nothing. While comfortable, it is also firm and reassuring to wear.

In terms of sound quality, the new product uses a 16mm driving unit, benefiting from SONY's profound acoustic accumulation and professional tuning technology, creating a broad stereo field, three frequencies clear, bass surging listening experience. Float Run's vocal unit is located next to the ear canal, making the user's music experience more comfortable and transparent. IPX4 waterproof rating, about 10 hours of battery life and fast charging and other functions, so that users can enjoy easy, convenient and secure music experience.
