≈3T Magnetic Flux
iBasso's innovative dual magnetic circuit design combined with the custom high magnetic strength N55 NdFeB magnet yields an astonishing magnetic flux of approximately 3T. This 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 more. The listening experience is outstanding.

15.4mm Maximized Diaphragm
The 3T-154 utilizes a 15.4mm diaphragm, one of the largest out there for an IEM (an increase in size of about 137% over popular 10mm diaphragms.) The 15.4mm large diaphragm has excellent sound pressure, and combined with the ≈3T magnetic flux, you can experience the most superb live music dynamics you've ever heard from an IEM.
Embossed, Beryllium-plated Diaphragm
The beryllium-plated diaphragm possesses remarkable internal resistance and exceptional rigidity. Additionally, the embossing technology further enhances rigidity, drastically minimizing distortion while enhancing sound precision.

Magnesium Alloy Shell
3T-154 uses high-hardness magnesium alloy as the shell material. Comparing the same volume, this magnesium alloy is about 36% lighter than aluminum alloy shells and 78% lighter than stainless steel shells. It also has stronger rigidity, impact resistance, reduces resonance caused by the unit, and has excellent stability.
1.2mm Quick Switch Plug
3T-154 has added the 1.2mm quick switch plug system which consists of (x4) 1.2mm large-size pins. Compared with the common 0.78mm pins, iBasso's system has a more robust contact area, the internal resistance is lower, the signal transmission loss is negligible, and the conductivity is outstanding!

2-Pin Detachable IEM Cable
The 3T-154 features a detachable cable design and adopts the standard 0.78" 2-pin interface, making cable replacement sourcing super convenient. This high-purity Silver-plated Copper cable is a standard, stock feature in the 3T-154 package.
