Product Description

Equipped with the industry's largest diaphragm at 15.4mm
the 3T-154 reproduces the most vivid dynamics ever seen. This large-diameter diaphragm, among the largest in the industry for IEMs, allows for unparalleled sound reproduction. Despite its significantly larger size compared to the general standard of 10mm diaphragm drivers, the unit size is 65% smaller than those utilizing a 12mm diaphragm, enabling simultaneous enlargement of the diaphragm while reducing the overall unit size. This 15.4mm large-diameter diaphragm delivers exceptional sound pressure levels, seamlessly integrated with the 3T magnetic flux circuit, resulting in exquisite dynamics unattainable with conventional IEMs.

Utilizing embossing technology, the beryllium-plated diaphragm boasts exceptional internal resistance and rigidity. 
The 3T-154 achieves superior sound quality by employing high-precision embossing techniques to enhance the durability and strength of the diaphragm, minimizing distortion to an absolute minimum.

With meticulously selected parts and iBasso technology, the 3T-154 ensures an optimal listening experience. 
Featuring a lightweight yet robust magnesium alloy shell, this material offers exceptional strength and rigidity while remaining lightweight. Compared to aluminum alloy, the magnesium alloy is 36% lighter with similar volume, possessing high rigidity, impact resistance, and excellent vibration damping properties, thereby minimizing sound distortion and ensuring stability.

The 3T-154 is compatible with 0.78mm 2Pin replacement connectors, providing flexibility in cable replacement. 
The standard cable is constructed with high-purity silver-plated copper, compatible with 3.5mm/4.4mm switches, allowing users to effortlessly switch between single-ended and balanced modes according to their preferences and connected equipment.

Employing a 1.2mm quick plug switch system renowned for its excellent conductivity
the 3T-154 features a cable equipped with four large 1.2mm pins. With a contact area approximately 2.3 times wider than the typical 0.78 pin plug exchange system, this design ensures durability and low internal resistance, facilitating high-conductivity signal transmission without loss. Included plug parts comprise 3.5mm and 4.4mm connectors.
