The Edifier Comfo Fit II use an open-ear fit, meaning they rest outside the ear canal rather than sealing it, and wingtips are included to help keep them in place during wear. They are fully wireless with no cables or neckband, and stereo speakers are built in for two-channel audio. The earbuds carry an IP55 ingress protection rating, making them sweat resistant and suitable for use during physical activity.
The Edifier Comfo Fit II cover a frequency range of 20 Hz to 20,000 Hz, spanning the full extent of standard human hearing. The earbuds do not include active noise cancellation or passive noise isolation, which is consistent with their open-ear design. A neodymium magnet is not part of the driver configuration.
The Edifier Comfo Fit II are equipped with a rechargeable battery that delivers 8 hours of playback per charge, while the included charging case extends the total available battery life to 32 hours. A full charge takes 1.5 hours, and a battery level indicator is on hand to keep track of remaining power. Wireless charging is not supported, so the earbuds rely on a wired connection to recharge.
The Edifier Comfo Fit II connect wirelessly via Bluetooth 5.3 with a maximum range of 10 meters, and USB Type-C is used for wired charging. Fast pairing and NFC pairing are not supported, and the earbuds do not include any aptX variants — covering aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, and aptX Voice — nor do they support LDAC, LDHC, or the AAC codec.
The Edifier Comfo Fit II support fast charging and can function as a headset, with a mute function available during calls. Controls are handled through a panel placed on the device itself rather than an in-line control panel, and voice prompts provide audio feedback for various functions. A travel bag is included in the box for storage and transport. The earbuds do not feature ambient sound mode, in-ear or on-ear detection for auto-pausing playback, a find-device function, or a body temperature sensor.
The Edifier Comfo Fit II include a noise-canceling microphone, which works to reduce background noise when the earbuds are used for calls or voice communication.
