Material choices, a compact ear-side body and a slender C-bridge help keep each earbud at 4.7g, while making room for a 10.95mm dual-magnet driver.

The engineering
behind all-day audio.
See how C-Flow’s fit, acoustics and controls support comfortable wear, clear sound and everyday ease.
Comfort and stability, designed together.
At just 4.7g each, C-Flow combines a lightweight build with an offset support layout, an ear-contouring shape and a flexible bridge for lasting comfort and a secure fit.
Your sound. Your surroundings. Ears open.
C-Flow sits outside the ear canal, sending audio through the air toward your ear while leaving the canal open for surrounding sounds.

Directional Steel-Mesh Design
Larger central openings and smaller side openings regulate sound transmission across the mesh. Together with the outlet’s position and orientation, this pattern helps direct audio toward the ear canal and reduce sideways leakage.
*Some sound may still be audible to others, particularly at higher volumes. Leakage varies with fit and surroundings.
NATURAL PRESENCE ACOUSTIC SYSTEM
Natural vocals. Music with body and detail.
A 10.95mm dual-magnet driver, composite diaphragm and open-ear tuning work together to bring voices into focus while retaining the richness and rhythm of music.
Driver & Diaphragm
10.95mm Dual-Magnet Dynamic Driver
An audio signal drives the voice coil within a magnetic field, moving the diaphragm to produce sound.
PU + LCP Composite Diaphragm
The composite combines flexibility and rigidity. Its response works with the driver and acoustic structure to shape the sound you hear.
Tuning & Measurements
See the tuning in the measurements.
Natural Presence tuning balances vocal clarity with musical body and detail. Its 16-level volume-aware EQ adjusts the tuning as volume changes, helping music retain its body at lower levels.
*Higher levels on the graph do not automatically mean better sound.
LDAC & Hi-Res Audio
LDAC supports high-resolution Bluetooth audio from compatible devices. C-Flow also supports AAC and SBC.

Less background noise.
Clearer conversations.
AI Voice Call Enhancement processes microphone audio to help reduce background noise sent to the other person, so your words come through clearly.
One microphone per earbud.
*Results vary with your surroundings. This processing does not reduce the surrounding sounds you hear.
Thoughtful design. Less everyday effort.
From the battery inside to the way audio switches and controls respond, C-Flow is designed to make everyday listening easier.
Each 4.7g earbud houses a rechargeable lithium-polymer battery for approximately 9 hours of playback per charge, supporting listening throughout your day. Recharges from the case extend total playback to approximately 70 hours, reducing the need to plug in on longer trips.
Based on LINKLIKE laboratory testing at 40% playback volume. Actual results vary with settings and use.
