The Sony WF-C710N adopt a true wireless, in-ear design with no cables or neckband, keeping the form factor clean and minimal. Each earbud weighs just 10.4 g, and the fit relies solely on the ear tip without wingtips for additional securing. They carry an IPX4 ingress protection rating, making them sweat resistant and suitable for workouts or commutes in light moisture. Stereo speakers are present in the design, while features such as RGB lighting, a UV light, and a display are not included, reflecting a straightforward, no-frills aesthetic.
The Sony WF-C710N include both active noise cancellation (ANC) and passive noise reduction, giving them two layers of sound isolation for blocking out environmental distractions. The driver unit measures 5 mm and covers a frequency range of 20 Hz to 20,000 Hz, spanning the full standard audible spectrum. The earbuds do not feature a neodymium magnet in their driver construction, and on the software side, spatial audio, Dolby Atmos, and Dirac Virtuo are not supported.
The Sony WF-C710N are equipped with a rechargeable battery that delivers 12 hours of playback per charge, dropping to 8.5 hours when ANC is active. The included charging case extends the total available listening time to 21.5 hours, and a full charge from empty takes 1.5 hours. A battery level indicator is present to keep track of remaining power. Wireless charging and solar battery functionality are not supported, so the earbuds rely on a wired connection via USB-C for recharging.
The Sony WF-C710N connect wirelessly via Bluetooth 5.3 with a maximum range of 10 m, and support fast pairing for quick device setup. The AAC codec is supported for audio transmission, though the earbuds do not include any aptX variants — including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, or aptX Voice — nor do they support LDAC or LDHC. Bluetooth LE Audio and Auracast are also absent, and NFC pairing is not available. USB-C is present for wired charging, though it does not serve as an audio connection in a wireless-only design.
The Sony WF-C710N come with a well-rounded set of practical features, including ambient sound mode, in-ear detection that pauses playback automatically when the earbuds are removed, and a find device function for locating misplaced earbuds. Multipoint connectivity allows simultaneous pairing with up to two devices, and fast charging is supported to reduce time spent waiting for a top-up. The earbuds can be used as a headset and include a mute function, with controls handled via a control panel on the earbuds themselves rather than an in-line remote. Voice prompts are present to assist with status updates, and a travel bag is included in the box. Notification readout, a body temperature sensor, and a built-in camera remote are not part of the feature set.
The Sony WF-C710N feature a noise-canceling microphone, which works to filter out background sounds during calls and voice interactions, helping to keep the speaker's voice clear in noisy environments.
