The Soundpeats C30 use an in-ear fit and are fully true wireless, meaning there are no cables or cords involved. They carry an IP54 ingress protection rating, making them sweat resistant and suitable for use during workouts or active sessions. Stereo speakers are present, delivering audio to both ears, while features like RGB lighting, wingtips, a display, UV light, and a neckband design are all absent from this model.
The Soundpeats C30 are equipped with active noise cancellation alongside passive noise reduction, giving them two layers of sound isolation from the surrounding environment. Each earbud uses a 12 mm driver unit with an impedance of 18 Ohms, and the frequency response spans from 20 Hz up to 40,000 Hz, covering a wide audible and beyond-audible range. The earbuds do not include a neodymium magnet, and there is no support for spatial audio, Dolby Atmos, or Dirac Virtuo processing.
The Soundpeats C30 offer 10 hours of battery life per charge, with the accompanying charging case extending total playback to 42 hours before needing to be plugged in. A full charge takes around 2 hours, and the earbuds feature a rechargeable battery along with a battery level indicator so users can keep track of remaining power. Wireless charging and solar battery functionality are not supported on this model.
The Soundpeats C30 connect wirelessly via Bluetooth 6 with a maximum range of 10 meters, and the charging case uses USB Type-C. For audio codecs, the earbuds support LDAC and AAC, while aptX in all its variants — including aptX Adaptive, aptX HD, aptX Low Latency, aptX Lossless, and aptX Voice — is not available. Bluetooth LE Audio and Auracast are also absent, and pairing options do not include fast pairing or NFC.
The Soundpeats C30 include an ambient sound mode for staying aware of surroundings, along with a mute function, voice prompts, and on-device touch controls. They can be used as a headset for calls, and fast charging is supported for quicker top-ups. A travel bag is included in the box, adding a small but practical convenience for storage and transport. Features not present include in-ear detection for auto-pause, a find-device function, notification reading, a built-in translator, an in-line control panel, a body temperature sensor, and a camera remote shutter.
The Soundpeats C30 feature a 6-microphone array with noise-canceling capability, helping to reduce background noise during calls and voice input for cleaner audio pickup.
