HAYLOU S40 Noise Cancelling Headphones Over Ear - LDAC Hi-Res

In this review the HAYLOU S40 stands out as a travel- and commute-friendly over-ear headset that prioritizes noise suppression and long battery life. The single biggest reason to consider the S40 is its 50dB hybrid active noise cancellation, which adapts to surroundings and noticeably reduces engines and train noise; combined with LDAC Hi-Res support and a long-lasting battery, it targets listeners who want detailed wireless audio without constant charging. The reviewer found the package balanced: strong ANC, clear calls, and app customization make it a practical everyday companion.

Key Features

• 50dB Hybrid ANC: Adaptive hybrid noise cancellation can reduce up to 95% of steady ambient sounds like airplane or subway noise for quieter listening.
• Hi-Res Audio with LDAC: LDAC support and dual titanium-plated diaphragm drivers deliver clearer, more detailed wireless playback when LDAC is enabled in the Haylou Sound app.
• Bluetooth 6.0: Newer Bluetooth offers a stable connection and lower latency for everyday listening and streaming across devices.
• 90H Playtime: Exceptional endurance provides up to 90 hours of playback (60 hours with ANC) and a 10-minute fast charge adds about 5 hours.
• Custom App & Multipoint: The Haylou Sound app enables EQ presets, ANC depth control, game mode, and seamless two-device switching for flexible use.
• Comfort Foldable Design: Soft protein leather earcups and an adjustable headband make the S40 comfortable for extended wear and easy to stow.

Who It's For

The HAYLOU S40 is best for frequent travelers and commuters who need strong, adaptive noise cancellation and long battery life to get through flights, trains, or long workdays without frequent charging. Audiophiles on a budget who want Hi-Res wireless playback with LDAC will appreciate the dual-driver setup and app-controlled EQ.

Those who should look elsewhere include listeners who require studio-accurate monitoring or wired pro-audio workflows, since the S40 is optimized for consumer listening and wireless convenience rather than professional reference use. Also, users who prefer ultra-compact true wireless earbuds for workouts may find over-ear bulkier than desired.
