Popular questions
Will the ANC in the Haylou S40 noticeably reduce the rumble of traffic?
The closed-back earcups themselves provide good isolation from external sounds, but in one review, active noise cancellation was weaker at low frequencies than on the S35. Adaptive mode helps with steady noise, although ANC performance may vary between units.Source:Expert reviews
How long does the charge last under normal use?
Haylou S40 are rated for up to 90 hours of use without ANC, while the review indicates around 60 hours with noise cancellation. Fast charging is also practical: 10 minutes plugged in provides up to 5 hours of listening.Source:SpecificationsExpert reviews
Are the Haylou S40 suitable for calls and team communication in games?
Yes, the detachable flexible microphone with ENC is designed for voice communication and transmits speech better than the built-in microphone. It can be turned off when headset mode is not needed.Source:SpecificationsExpert reviews
Can Haylou S40 be connected via a cable to a device with a 3.5 mm jack?
No, there is no 3.5 mm analog input here. The included USB-C cable is suitable for charging and wired playback, but according to the review, the 3.5 mm adapter does not work.Source:SpecificationsExpert reviews
Is it worth switching from Haylou S35 to Haylou S40?
The switch is justified if you value more detailed sound, LDAC, a detachable microphone, and additional settings via the app. The new model also supports Bluetooth 6.0 and use with two devices, but in one review its ANC performed worse at low frequencies than the S35.Source:SpecificationsExpert reviews
