Product Overview
CMF BY NOTHING builds the Clip Pro around an open ear, clip-on form factor rather than a sealed in-ear tip, aiming the design at listeners who want audio without blocking the ear canal. The clip uses a custom 3-point contact design, spreading pressure across three areas of contact to hold the earbud in place during movement rather than relying on a single pressure point.
Audio comes from 10.8mm dynamic drivers, which CMF certifies for Hi-Res Audio and positions as delivering both bass and clear highs despite the open ear format. A Voice Pickup Unit with a 4 HD mic system is built specifically to separate the wearer's voice from background noise during calls.
Controls run through a Smart Dial that can be spun or pressed, and the earbuds pair with the Nothing X app for Anti-Leakage Mode, Spatial Audio and custom EQ settings, on top of the core Bluetooth 5.4 connection.

Key Features
A 5.92 gram clip spreads pressure across three contact areas for a secure, slip-free fit.
Dynamic drivers certified for Hi-Res Audio deliver bass and clear highs.
Separates the wearer's voice from background noise during calls.
A physical dial that can be spun or pressed for intuitive playback control.
Supports dual-device connectivity and a Low Lag Mode.
Design and Build Quality
Each Clip Pro earbud weighs 5.92 grams and clips on using a custom 3-point contact design, spreading grip across three points rather than one. The overall package measures about 3.15 inches long by 3.15 inches wide by 1.38 inches tall and weighs about 0.11 pounds in coral, under model and part number B189.
Inside, 10.8mm dynamic drivers are certified for Hi-Res Audio, paired with a 4 HD mic Voice Pickup Unit for call clarity. A physical Smart Dial sits on the earbud for control by spinning or pressing, and the design connects over Bluetooth 5.4 with dual-device connectivity and a Low Lag Mode.
CMF backs the Clip Pro with a 1 year manufacturer warranty.
Performance in Everyday Use
Playtime is listed at up to 10 hours of continuous use per charge, with 32.5 hours total once charging case cycles are included, running on Bluetooth 5.4 for what CMF describes as rock-solid connection stability. Dual-device connectivity lets the earbuds stay paired to two sources at once, and Low Lag Mode is built in for latency-sensitive use.
The 4 HD mic Voice Pickup Unit is designed to separate a wearer's voice from environmental noise in real time, which CMF ties specifically to staying clear on a crowded street or in strong wind rather than only in quiet rooms. The 3-point clip is the mechanism responsible for keeping the 5.92 gram earbud secure during activity without an in-ear tip to anchor it.
Software features, including Anti-Leakage Mode, Spatial Audio and custom EQs, are accessed through the Nothing X app rather than on the earbud itself, alongside the physical Smart Dial for everyday volume and playback control.

Who Should Buy It
- Calls where situational awareness matters more than noise isolation
- Workouts and activity needing a secure clip-on fit
- Anyone wanting Hi-Res certified sound from an open ear design
- Nothing X app users wanting custom EQ and Spatial Audio
- Anyone wanting maximum noise isolation or deep bass from a sealed in-ear or over-ear design
- Open ear design does not seal the ear canal, so it offers less passive noise isolation than an in-ear bud
- Smart Dial and app features add a learning curve compared with simple tap controls
- Advanced features like Spatial Audio and custom EQ require the separate Nothing X app
- At 5.92 grams per earbud, the clip relies on consistent contact pressure rather than an in-ear seal to stay put
