The Flat-Head Plug "Resurrected" By Titanium Alloy: This Retro Trend Is Simply Amazing!

Once upon a time, it was the "standard equipment" for everyone in the headphone industry. However, with the rise of in-ear and noise-cancelling headphones, problems such as leakage, weak bass, and cavity resonance made the flat-head earphones gradually fade out of the public's view and become a nostalgic choice for niche players.

But who could have imagined that with the assistance of materials science, a "titanium alloy flat-head plug" emerged unexpectedly. Not only did it solve many problems of the traditional design, but it also triggered a "retro sound quality revival" in the wave of consumption upgrade!

Titanium Alloy: Unlocking the "Golden Finger" for Flat Head Speakers

The core problems of flat head speakers actually lie within the "cavity" - the open structure leads to the loss of low-frequency, the lack of rigidity of traditional materials causes resonance, ultimately making the sound muddy and loose. However, the addition of aerospace-grade Gr5 titanium alloy directly addresses these issues head-on.

As a commonly used material in the aerospace field, Gr5 titanium alloy has inherent acoustic advantages:

1) High hardness and low resonance can effectively suppress excessive vibrations in the cavity, making the sound base clear and transparent. The smooth texture of violin bowing and the delicate details of human breathing can all be accurately captured;

2) The structural stability is at its peak, and the sound propagation path remains consistent. The horizontal sound field is directly "superior" - it feels as if the band is extending half a meter on both sides of your ears, with an immersive experience that is fully achieved;

3) The weight is also extremely friendly! Its density is only 60% of that of steel. Wearing it on the ears is almost "unnoticeable", and there will be no pressure during long commutes or binge-watching.

From Materials to Craftsmanship: Embedding "Precision" Deep Within

A good material requires a good craftsmanship; otherwise, even the highest-quality titanium alloy will struggle to showcase its full potential. The manufacturing process of this flat-head plug can be described as a "fanatic's delight":

1) Five-axis CNC Precision Machining: Using a Japanese STAR five-axis machine, the titanium block is meticulously cut layer by layer, with the error controlled at the micrometer level to avoid any impact on sound quality due to tolerances;

2) Mirror-Glass Surface Treatment: The 316 stainless steel hardware components are hand-polished, not only maintaining an excellent appearance but also reducing the interference caused by microscopic bumps in sound wave reflection;

3) Modular Wire Design: Without the need for specialized tools, one can freely switch between 3.5 single-ended/4.4 balanced interfaces, and choose between over-ear and direct-insertion wearing methods, adapting to different scenarios as needed.

Tuning Philosophy: Nature Is The Best Sound Experience

Compared to overloading parameters, this titanium alloy flat-head speaker truly understands that "sound quality is king".

32Ω impedance + 115dB sensitivity. It can be easily driven by the phone's direct power supply without the need for an additional player; the total harmonic distortion (THD) is controlled below 0.1%. Even when the sound pressure is as high as 100dB, the sound remains stable and pure.

Its tonal tuning does not follow an "extreme" approach but focuses on "natural balance":

1) The low frequencies do not strive for a powerful impact. Instead, they gently descend with elasticity, stopping precisely at the right point, avoiding the suppression of mid-high frequency details. This allows for long listening without fatigue.

2) The mid-high frequencies have a slightly sweet tone. Whether it's the tender interpretation of human voices or the bright texture of instruments, they are extremely compelling.

3) The sound field is clearly layered, and the positioning of the instruments is precise. It feels as if the recording studio has been directly brought to one's ears, restoring the music to its most authentic form.

Not just one hit product: Innovative material design sets new trends in the industry

The success of this titanium alloy flat-head plug was not accidental.

Under the same brand, there is also a titanium alloy earplug known for its "microscope-level resolution". By optimizing the purity of titanium alloy and the cavity structure, it suppresses background noise to the extreme. Even the entry-level model retains the core titanium alloy framework design, allowing ordinary consumers to experience the material advantages at an affordable price.

Market data never lies: Within just three months of its launch, this series of earphones achieved a sales volume of over 1,500 units. "Comfortable to wear" and "Natural sound quality" have become the most frequently mentioned words in user reviews. Behind this is everyone's pursuit of “true sound quality” under the upgrading of consumption-high-end materials are no longer gimmicks, but the core of truly enhancing product competitiveness.
