Over-ear noise-canceling headphones are no longer limited to premium price ranges. Many brands are now offering powerful features such as hybrid ANC, Hi-Res audio support, and long battery life at much more affordable prices. The HAYLOU S40 aims to be one of those value-focused options.
Designed for everyday listening, travel, and work, the HAYLOU S40 brings together features like 50dB hybrid active noise cancellation, LDAC Hi-Res wireless audio, Bluetooth 6.0 connectivity, and up to 90 hours of battery life. It also includes multiple microphones for clear calls and an app that allows users to customize sound settings.
With its foldable design and comfortable earcups, the S40 is built to be practical for long listening sessions. At a price that is far below most premium noise-canceling headphones, the S40 attempts to deliver strong performance without stretching your budget.
HAYLOU S40 Features
One of the standout features of the HAYLOU S40 is its 50dB hybrid active noise cancellation system. This technology can reduce up to 95% of surrounding noise, helping users stay focused while listening to music, podcasts, or taking calls.
The hybrid ANC system works by combining external and internal microphones to detect and cancel unwanted sounds. It is particularly effective against consistent background noise such as airplane engines, car traffic, and subway trains.
The headphones also include adaptive ANC technology, which automatically adjusts the noise cancellation level depending on your surroundings. This allows the headphones to maintain effective noise reduction without requiring manual adjustments.
For sound quality, the HAYLOU S40 focuses on delivering detailed audio through 40mm + 20mm titanium-plated diaphragm dual drivers. This setup is designed to produce a wide soundstage with balanced bass, clear vocals, and detailed highs.
The headphones are Hi-Res Wireless Audio certified and support the LDAC codec, which allows compatible devices to transmit more audio data than standard Bluetooth codecs. This results in improved clarity and more accurate sound reproduction.
Users can enable LDAC through the Haylou Sound App, unlocking higher-quality wireless audio for supported devices.
Connectivity is handled by Bluetooth 6.0, which offers faster data transfer and a more stable connection compared to earlier versions of Bluetooth.
For calls, the S40 includes six microphones in total — five built-in microphones along with one detachable microphone. These microphones use AI algorithms to isolate your voice while reducing background noise.
This setup helps improve voice clarity during calls, making the headphones suitable for remote work, online meetings, and voice chats.
Battery life is one of the strongest features of the HAYLOU S40. With ANC turned off, the headphones can deliver up to 90 hours of playback on a single charge.
Even with active noise cancellation enabled, the headphones still provide up to 60 hours of listening time, which is far above the industry average.
The headphones also support fast charging, where a 10-minute charge provides around 5 hours of playback. This feature is especially useful when you need a quick power boost before leaving home.
In addition, the S40 supports USB-C wired connectivity, allowing you to use the headphones with a cable when needed.
The Haylou Sound App gives users greater control over their listening experience. Through the app, you can adjust sound profiles, customize EQ settings, and control the depth of noise cancellation.
The app also includes features such as preset sound profiles, device renaming, and a game mode designed to reduce audio latency while gaming.
Another useful feature is multipoint connection, which allows the headphones to connect to two devices simultaneously. This makes it easy to switch between devices such as a laptop and smartphone without needing to reconnect manually.
Comfort plays an important role in over-ear headphones, and the HAYLOU S40 is designed with long listening sessions in mind.
The headphones feature soft protein leather earcups that provide a comfortable fit around the ears. The adjustable headband allows users to find a personalized fit, making the headphones suitable for extended use during work, travel, or workouts.
The foldable design also makes the headphones easier to carry in a backpack or travel bag.
The HAYLOU S40 is available in the United States for $54.99, with limited-time offers currently available on Amazon. At this price, the headphones fall into the budget category while still offering features commonly found in more expensive models.

The HAYLOU S40 stands out mainly because of the number of features it offers at a very affordable price.
The hybrid ANC system performs well for everyday situations, particularly when dealing with consistent background noise such as transportation or office environments. While it may not completely match the performance of premium flagship headphones, it still delivers noticeable noise reduction for the price.
Sound quality is also respectable. The dual driver setup combined with LDAC support helps produce clear and detailed audio. Music sounds balanced, with vocals remaining sharp while bass stays controlled rather than overpowering the mix.
Battery life is arguably the strongest aspect of the S40. With up to 90 hours of playback, users can go days without needing to recharge the headphones. Even with ANC enabled, the 60-hour battery life is more than enough for long trips or extended work sessions.
The inclusion of multipoint connectivity and app customization also adds flexibility, making the headphones more practical for people who use multiple devices throughout the day.
Overall, the HAYLOU S40 delivers a strong combination of features, comfort, and battery performance for its price category.
If you are looking for budget-friendly over-ear headphones with strong battery life and useful features, the HAYLOU S40 is definitely worth considering.
These headphones are especially suitable for travelers, remote workers, students, and casual listeners who want noise cancellation and long battery life without paying premium prices.
However, if you prioritize premium materials or industry-leading noise cancellation, you might prefer more expensive flagship models.
The HAYLOU S40 proves that affordable headphones can still deliver impressive features. With hybrid ANC, Hi-Res audio support, multipoint connectivity, and an exceptional 90-hour battery life, the S40 offers excellent value for its price.
