HAYLOU S40 ANC Wireless Headphones Bluetooth 6.0 Hi-Res Audio Over Ear Headset 50dB Hybrid Active Noise Cancellation Earphones

Noise can be reduced at three levels, and most reviews confirm that ANC works, though it's not perfect — in loud environments like subways or streets, you'll hear approximately 15–20% of the sound. The Haylou app is intuitive and offers multiple sound modes. The headphones can also be used via a USB-C cable, which is useful for long workdays. The package includes a cable and adapter.

Some buyers noticed that ANC deactivates when multipoint mode is enabled. The external microphone connected via Bluetooth has lower quality than the internal one or the one connected via USB-C cable — according to reviews, this is likely a firmware issue. At maximum volume, sound is audible to those around you. Some also noticed a plastic sound when moving the headphones to the sides, though this is less noticeable at higher volumes.
