≈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.

Good for the price

Audiophile IEM under $200, yep. Comments are made given price point. Decent timbre, clear, coherent. Lacks the detail retrieval of higher price IEMs but at this price it’s good, Bit disappointed in bass, was expecting more texture and depth give the size of the driver. But for the price it’s just fine.

Big sound, small cost!

I am very pleased with the overall excellent performance of the 3T-154!
Tonality is well-balanced with instrumental timbre very realistic. Overall soundstage and imaging are quite lifelike and exhibit a surprising sense of you-are-there. The sound is expansive with superb dynamics.
Although the shells are large, I find them comfortable for long term listening. They are easily driven but also scale well with my desktop components and can compete without apologies when compared to far more expensive IEMs!
Well-done, iBasso!
