The Sony WF-C700N true wireless noise-canceling earbuds pair featherweight 4.6-gram Ergonomic Surface Design shells with a custom 5 mm high-compliance driver, Sony's Digital Sound Enhancement Engine (DSEE), Active Noise Cancellation, and 2-device Bluetooth 5.2 Multipoint inside a pocket-sized 31-gram cylindrical charging case.
5 mm high-compliance driver, DSEE upscaling, and 5-band custom EQ
Despite its ultra-compact footprint, the WF-C700N houses a custom 5 mm dynamic driver engineered with a high-compliance diaphragm that delivers punchy low-end bass and clean midrange vocal separation across the 20 Hz – 20,000 Hz spectrum. Sony's Digital Sound Enhancement Engine (DSEE) restores high-frequency harmonics lost in compressed streaming audio, and the Sony Sound Connect (Headphones Connect) app provides a 5-band equalizer with Clear Bass adjustment, Find Your Equalizer, and 360 Reality Audio ear-shape personalization.
Active Noise Cancellation, Wind Noise Reduction, and physical button controls
Noise-sensing microphones inside each earbud suppress steady background transit and office hum while a recessed Wind Noise Reduction mesh structure minimizes outdoor wind buffeting during both ANC listening and hands-free phone calls. Pressing the left earbud button switches seamlessly to Ambient Sound Mode, which uses the feedforward microphones to let in surrounding traffic or announcements across 20 adjustable transparency steps (with an optional Voice Focus toggle) or automates mode switching via Adaptive Sound Control. Unlike capacitive touch earbuds that can trigger accidentally when adjusting fit, the WF-C700N uses tactile physical push buttons on both earbuds and supports single-earbud mono listening on either the left or right unit.
IPX4 sweat resistance, Bluetooth 5.2 Multipoint, and cylindrical USB-C case
Shaped using extensive human ear-cavity data, each 4.6 g earbud sits securely for commutes and workouts and carries an IPX4 water-resistance rating against sweat and rain splashes. Wireless connectivity covers Bluetooth 5.2 with 2-device Multipoint, Google Fast Pair, and Microsoft Swift Pair. Battery life reaches up to 7.5 hours with ANC on (up to 10 hours with ANC off), doubled to 15 hours (ANC on) / 20 hours (ANC off) by the textured 31 g cylindrical charging case, with a 10-minute USB Type-C quick charge adding up to 60 minutes of playback.
Bangladesh buyer checklist
Before ordering the Sony WF-C700N from any seller in the BiponiBD catalog, confirm the color variant (Black, White, Lavender, or Sage Green), check that the hybrid silicone eartips (SS, M, LL) and USB-C charging cable are sealed in the box, and verify seller warranty coverage.
