The EarFun Wave Life uses an over-ear fit and weighs 264 g, striking a balance between coverage and portability. It features a foldable design, making it more compact for storage or travel, though no travel bag is included. The headphone comes with a detachable, tangle-free cable and houses stereo speakers within a closed-back enclosure. It is not designed for kids and carries no water resistance rating, so it is best kept away from moisture.
The EarFun Wave Life is equipped with active noise cancellation alongside passive noise reduction, giving it two layers of sound isolation. Its 40 mm driver unit covers a frequency range of 20 Hz to 20,000 Hz, spanning the full extent of standard human hearing. The headphone does not support spatial audio and does not use a neodymium magnet in its driver construction.
The EarFun Wave Life runs on a built-in 500 mAh rechargeable battery that is not removable, delivering up to 60 hours of playback under standard conditions and 37 hours with active noise cancellation enabled. It charges fully in 2 hours via USB Type-C and includes a battery level indicator so users can keep track of remaining charge. Wireless charging and solar charging are not supported.
The EarFun Wave Life supports both wireless and wired connectivity, with the wireless side handled by Bluetooth 5.4 across a maximum range of 15 m and an audio latency of 55 ms. It does not include any high-resolution or enhanced audio codecs — aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, AAC, LDAC, and LDHC are all absent — nor does it support Bluetooth LE Audio or Auracast. Fast pairing and NFC-based pairing are likewise not available.
The EarFun Wave Life includes four microphones with noise-canceling capability, making it suitable for use as a headset for calls. It also features an ambient sound mode, allowing users to let in environmental audio when needed. Controls are handled through an on-device panel rather than an in-line remote on the cable. The headphone supports multipoint connection with up to two devices simultaneously, though it lacks in/on-ear detection for automatic playback pausing and does not offer a dedicated mute function.
