KBEAR Unveils the New TBX Featuring a 10mm CVD Carbon Fiber Dynamic Driver and Dual-Chamber Acoustic Structure

 

KBEAR officially introduces the brand-new TBX (Tourbillon-X), a dynamic driver in-ear monitor inspired by the precision and mechanical elegance of a tourbillon movement.

 

Designed around the concept of precision control and balanced acoustic performance, the TBX combines a newly developed 10mm CVD-coated carbon fiber diaphragm driver with a single external magnetic dual-chamber structure  to deliver a cleaner, more refined, and more natural listening experience.

 

Rather than focusing purely on aggressive detail or exaggerated tuning, the TBX aims to create a sound signature that feels engaging, controlled, and comfortable for long listening sessions.

 

From Pop and ACG to vocals, electronic music, and casual HiFi listening, the TBX is designed to provide an immersive and versatile everyday audio experience.

 

 

 

 

01  Precision of Motion, Perfection in Sound
Newly Developed 10mm CVD-Coated Carbon Fiber Dynamic Driver

 

At the heart of the TBX is a newly engineered 10mm dynamic driver equipped with a CVD-coated carbon fiber diaphragm.

 

Compared to conventional diaphragm materials, carbon fiber provides higher rigidity with lower weight, helping reduce unwanted vibration and distortion while improving transient response and overall resolution.

 

The result is:

•  Faster and cleaner bass response

•   More natural and focused vocal presentation

•  Better treble extension with improved micro-detail retrieval

 

Instead of delivering an overly sharp or analytical sound, the TBX focuses on achieving a more refined and controlled presentation.

 

 

Whether reproducing vocal textures, instrument overtones, or dynamic bass impact, the TBX maintains a balanced and coherent sound character.

 

 

02  Single External Magnetic Dual-Chamber Structure
Optimized Acoustic Airflow for Cleaner Sound Performance

 

To further improve acoustic stability and sound separation, the TBX adopts a single external magnetic dual-chamber design.

 

 

The dual-cavity structure helps optimize internal airflow and reduce unwanted resonance, resulting in a cleaner background and smoother frequency transition.

 

 

The TBX also integrates an optimized N52 magnetic circuit system, allowing faster diaphragm movement and improved dynamic control.

 

 

Compared with conventional single-chamber structures, the TBX delivers better layering, improved separation, and a more spacious presentation — especially in complex tracks with multiple instruments.

 

 

 

 

03  Balanced Yet Engaging Sound Tuning
Designed for Comfortable Everyday Listening

The TBX is tuned with a balanced and natural sound profile that prioritizes musicality and long-term listening comfort.

 

The bass delivers satisfying depth and impact without overpowering the mids.

 

Vocals remain naturally positioned with solid density and clarity, while the treble provides good extension and air without becoming harsh or fatiguing.

 

 

 

This versatile tuning style makes the TBX suitable for a wide variety of genres:

  •  Pop Music

  •   ACG

  •   Male & Female Vocals

  •   Electronic Music

  •   Instrumental Tracks

  •   Casual HiFi Listening

 

 

Easy to drive and highly versatile, the TBX is designed to work naturally across smartphones, portable gaming devices, PCs, and music players.

 

It is an earphone built not only for detail retrieval — but also for daily enjoyment.

 

 

 

04  CNC Alloy Craftsmanship with Ergonomic Comfort
Premium Metal Texture with Stable All-Day Fit

 

 

The TBX features a CNC-machined alloy shell with refined surface detailing, combining durability with a sophisticated metallic appearance.

 

Its carefully sculpted housing structure enhances both visual texture and structural stability while maintaining a compact and modern profile.

 

To ensure long-term comfort, the TBX also adopts an ergonomic cavity design that fits naturally inside the ear.

 

Whether used for commuting, gaming, entertainment, or extended music sessions, the TBX is designed to provide a secure and comfortable wearing experience.

 

 

 

05  High-Quality OFC Silver-Plated Cable
Multiple Plug Options for Different Devices

 

The TBX comes equipped with a high-quality OFC silver-plated cable for stable signal transmission and cleaner sound performance.

 

Multiple plug versions are available to better suit different user scenarios:

•   3.5mm

•   3.5mm with Microphone

•   Type-C with Microphone

•    0.78mm 2Pin Detachable Design

 

The detachable cable system also allows users to upgrade or replace cables more conveniently.
