Spatial audio is supported, adding a dimensional quality to playback, though Dolby Atmos and Dirac Virtuo are not included. The earbuds do not feature a neodymium magnet, and neither active noise cancellation nor passive noise reduction is present, which is consistent with their open-ear design.
The Haylou Earhook 1 carry a 60 mAh rechargeable battery that delivers up to 9 hours of playback per charge, while the 600 mAh charging case extends the total available battery life to 31 hours.

Fast pairing and NFC-based pairing are not available either, keeping the connection setup straightforward without those extras.
The Haylou Earhook 1 support multipoint connectivity for up to two devices simultaneously and can function as a headset for calls, with a mute function available for added control during conversations. Fast charging is supported, and voice prompts are included to assist with device feedback. Controls are placed on the device itself rather than on an in-line panel, and a travel bag is included in the box. Features such as ambient sound mode, in-ear detection, a find-device function, notification readout, a built-in translator, a body temperature sensor, and a camera remote are not part of this product.
The Haylou Earhook 1 are equipped with a four-microphone setup that includes noise-canceling microphone technology, helping to reduce unwanted background sound during calls and voice interactions.
