Hong Kong, August 13, 2026 — HAYLOU today introduced the FlowLoop S33, a new wireless over-ear headphone designed for people who want uninterrupted listening throughout their daily routines. Combining up to 100 hours of battery life, lightweight comfort, and practical noise cancellation, FlowLoop S33 is built to deliver a reliable audio experience from daily commutes and work sessions to travel and relaxation.

Designed Around Everyday Freedom

Modern users rely on headphones throughout the day — during commuting, studying, working, traveling, and relaxing. However, frequent charging and uncomfortable designs can interrupt the experience.

FlowLoop S33 addresses these everyday frustrations with a long-lasting battery and comfort-focused design, giving users more time to enjoy their music, podcasts, calls, and entertainment without worrying about battery life.

Up to 100 Hours of Battery Life

FlowLoop S33 delivers up to 100 hours of playback on a single charge, allowing users to go days or even a full week of regular use without reaching for a charger. With ANC enabled, users can still enjoy up to 70 hours of uninterrupted listening.

Whether on a long journey, working remotely, or using headphones throughout the day, FlowLoop S33 is designed to keep up with modern lifestyles.

Lightweight Comfort for Long Listening Sessions

Built for extended wear, FlowLoop S33 features a lightweight 250g design that helps reduce pressure during long listening sessions. Soft ear cushions and a foldable structure provide a comfortable and portable experience for daily mobility.

From morning commutes to evening entertainment, FlowLoop S33 is designed to feel effortless wherever users go.

Practical Noise Cancellation and Immersive Audio

FlowLoop S33 features hybrid active noise cancellation with up to -45dB noise reduction, helping users stay focused in everyday environments such as public transportation, offices, and coffee shops.

Through the HAYLOU Sound App, users can customize noise control modes and EQ settings based on different preferences. With LDAC support and Hi-Res certification, FlowLoop S33 delivers detailed and immersive sound for music lovers.

A New Everyday Standard for Wireless Headphones

With its combination of ultra-long battery life, lightweight comfort, and practical audio features, HAYLOU FlowLoop S33 is designed for users who want headphones that simply fit into everyday life.
