iBasso 3T-154 Dynamic Driver In-Ear Monitor (OPEN BOX)

Remarkable Performance
3T-154
Dynamic Driver In-Ear Monitor

• ≈3T Magnetic Flux
• 15.4mm Diaphragm
• Magnesium Shell
• 1.2mm Quick Switch Plug System

≈3T Magnetic Flux
Impressive Micro Detail & Exceptional Transient Response

Innovative dual magnetic circuit design combines with the custom high magnetic strength N55 NdFeB magnet presenting an astonishing magnetic flux of approximately 3T, which is nearly double compared to the current 1.6T magnetic flux of other flagship IEMs. The strong magnetic flux of the 3T-154 has many advantages such as superb transient response, concise detailed bass, better micro details and many other music qualities. The listening experience is outstanding.

3T-154 ≈3T
Typical IEMs＜1T
Other Flagship IEMs ≤1.6T

15.4mm Maximized Diaphragm
Dynamics of Live Music

The 3T-154 utilizes a 15.4mm diaphragm, a maximized size of diaphragm for an IEM. The 15.4mm large diaphragm has excellent sound pressure, and combined with the ≈3T magnetic flux, you can experience the most superb dynamics that you have ever heard from an IEM.

Beryllium-plated Diaphragm
Utilizing Embossing Technology

The beryllium-plated diaphragm possesses remarkable internal resistance and exceptional rigidity. Additionally, the embossing technology further enhances the diaphragm's rigidity, which drastically minimizes distortion while enhancing sound precision.

• Japanese Daikoku CCAW voice coil
• High-precision CNC diaphragm bracket.
• Replaceable nozzle design.

Magnesium Alloy Shell
Lighter & Stronger

3T-154 uses high-hardness magnesium alloy as the shell material. Comparing the same volume, this magnesium alloy is about 36% lighter than an aluminum alloy. It also has stronger rigidity, impact resistance, reduces resonance caused by the unit, and has excellent stability.

When compared with aluminum alloy shell,
Weight reduced by 36%

When compared with stainless steel shell,
Weight reduced by 78%

1.2mm Quick Switch Plug System
Outstanding Conductivity

3T-154 has added the 1.2mm quick switch plug system, which consists of four 1.2mm large-size pins. Compared with the common 0.78mm*4 pins, our system has a more robust contact area, the internal resistance is lower, the signal transmission loss is negligible, and the conductivity is outstanding!

The 1.2mm pin cross-sectional area is 2.37times that of the 0.78mm pin

0.78mm Two-pin Detachable IEM Cable
High Purity Silver-plated Copper Cable is A Standard

The 3T-154 is detachable cable design, adopts standard 0.78 two-pin interface, which accommodates sourcing a cable replacement as very convenient.

High purity silver-plated copper cable is a standard.
