HALO HAYLOU S40 Over-Ear Headphones

The HALO HAYLOU S40 is a pair of over-ear wireless headphones with hybrid active noise cancellation and Bluetooth 6.0 connectivity. It supports Hi-Res Audio and LDAC codec for high-quality wireless listening. The 40 mm titanium-plated diaphragm drivers deliver a 97 dB signal-to-noise ratio and 32 ohm impedance. A detachable boom microphone joins five built-in mics for AI-enhanced voice pickup during calls.

90-Hour Battery and USB-C Charging

Up to 90 hours of playback are available with noise cancellation off, and 60 hours with it active. A 10-minute charge adds roughly 5 hours of listening time, while a full charge takes 2.5 hours via USB-C. The lithium-ion cell powers the headset without increasing weight to 0.35 kg. Passive wired use is possible through the USB-C port, though the supplier advises against operating the headphones while they charge.

Hybrid ANC Up to 50 dB Reduction

Hybrid ANC reduces ambient noise by up to 95 percent, targeting low-frequency drone such as engines and trains. Adaptive algorithms adjust cancellation depth automatically to match the environment. Six microphones feed the AI noise-suppression system for clear calls even in wind or traffic. Bluetooth 6.0 provides a stable, low-latency link for extended sessions without connection drops.

Questions about this item

How do I pair the S40 with my phone and what step do people often miss?

Turn on the headphones, hold the power button until the indicator flashes, then select "HAYLOU S40" in your phone's Bluetooth 6.0 menu. The step many miss is enabling LDAC in the Haylou Sound app for Hi-Res audio.

Which parts will need replacement after extended use?

The ear cushions and the detachable microphone are the components most likely to wear out. The internal lithium polymer battery is not user-replaceable and supports up to 90 hours playtime per charge.

What is the first limitation I will hit during a long listening session with ANC on?

With active noise cancellation enabled, the battery lasts 60 hours before needing a 2.5 hour recharge. A 10 minute quick charge adds 5 hours of playback if you run low.
