Haylou S40 VS Skullcandy Hesh 540

Both the Haylou S40 and Skullcandy Hesh 540 have an over-ear fit, a detachable cable, and a foldable design, making them suitable for portability and convenience. The Haylou S40 includes a tangle-free cable, whereas the Skullcandy Hesh 540 also offers a tangle-free cable and additionally comes with a travel bag, which the Haylou S40 does not include.

Neither product offers water resistance, and neither features an open-back design or stereo speakers, as both are equipped with stereo speakers. Both products are not designed specifically for kids, either.

Overall, while both headphones have similar core design features like the fit and foldability, the Skullcandy Hesh 540 has the added benefit of a travel bag, which is not included with the Haylou S40.

Both the Haylou S40 and Skullcandy Hesh 540 feature active noise cancellation (ANC) and support spatial audio, offering enhanced sound experiences. They also share the same frequency range of 20 Hz to 20,000 Hz and the same 40 mm driver unit size, providing a similar foundation for sound quality.

However, there are differences in impedance and sound pressure level. The Haylou S40 has an impedance of 32 Ohms and a sound pressure level of 97 dB/mW, while the Skullcandy Hesh 540 has a slightly higher impedance of 36 Ohms and a notably higher sound pressure level of 119.4 dB/mW, which could impact their overall loudness and efficiency.

Both models feature passive noise reduction, and neither has a neodymium magnet. These sound specifications point to a broadly similar performance profile, with the Skullcandy Hesh 540 offering a slightly higher output in terms of sound pressure level.

The Haylou S40 offers a significantly longer battery life than the Skullcandy Hesh 540, with a total of 90 hours compared to 65 hours. Both models share several key features, including USB Type-C charging, a battery level indicator, and a rechargeable battery. Neither product supports wireless charging or has a solar power battery.

Both the Haylou S40 and Skullcandy Hesh 540 have a non-removable battery, which means users will not be able to swap out the battery for a new one during use. However, the Haylou S40's longer battery life could make it more convenient for extended usage without needing a charge.

In summary, the Haylou S40 stands out with its longer battery life, while both products offer similar charging capabilities and a rechargeable, non-removable battery.

Both the Haylou S40 and Skullcandy Hesh 540 offer wireless and wired connectivity, but they differ in several key wireless features. The Haylou S40 uses Bluetooth version 6, while the Skullcandy Hesh 540 features Bluetooth version 5.3. The Haylou S40 also supports LDAC and AAC audio codecs, whereas the Skullcandy Hesh 540 does not support AAC.

In terms of audio latency, the Haylou S40 has a latency of 80 ms, while the Skullcandy Hesh 540 has a lower latency of 50 ms, potentially resulting in a quicker response time on the latter. The Haylou S40 has a maximum Bluetooth range of 20 m, double that of the Skullcandy Hesh 540, which has a range of 10 m.

Both headphones lack support for features like fast pairing (except the Skullcandy Hesh 540) and Bluetooth pairing using NFC, and neither model includes aptX Adaptive, aptX HD, or LDAC. Overall, the Haylou S40 offers a stronger Bluetooth range and codec support, while the Skullcandy Hesh 540 features lower latency and fast pairing functionality.

Both the Haylou S40 and Skullcandy Hesh 540 are equipped with a noise-canceling microphone and ambient sound mode, offering similar core features in this category. However, there are a few notable differences in their functionality. The Haylou S40 features 11 microphones, while the Skullcandy Hesh 540 has 4 microphones, which could impact the overall microphone performance and voice clarity.

Both models support multipoint connectivity with a count of 2, allowing for simultaneous connection to two devices. The control panel placement differs, as the Haylou S40 has the control panel placed on the device, while the Skullcandy Hesh 540 does not have this feature, relying instead on the in-line control panel, which both models share.

Additionally, the Haylou S40 does not support in/on-ear detection, while the Skullcandy Hesh 540 does. Both headphones can be used as a headset, making them versatile for calls or communication purposes.
