Features: -

>Wide Frequency Response Range

A wider frequency response range allows for greater accuracy and realism in reproducing instruments, capturing both the primary fundamental frequencies and the harmonic overtones effectively. Many earphones on the market can only handle the main frequency ranges and fall short in reproducing overtones due to their limited frequency response.

>Easy to Drive

Thanks to its advanced technology, the Performer 5+2 is highly efficient and easy to drive. While a high-quality source will maximize its potential, it still provides excellent sound quality when used with portable dongles or Bluetooth DAC/Amps.

>Exceptional Bass and Treble

The addition of two dynamic drivers and a micro planar unit, along with AFUL’s unique acoustic and circuit design, ensures that the bass texture, depth, treble resolution, and instrument separation are all top-notch.

Technology: -

>High-precision 3D Printed Acoustic Tube Structure

>LC Network Frequency Division Correction Technology

>High-Damping Air-Pressure Balance System

By integrating precise and complex 3D acoustic structures with RLC network crossovers, AFUL has significantly elevated acoustic performance. This advanced modeling and design of the "acoustic structure-speaker-RLC network" has achieved a substantial leap in sound quality.

Exceptional low-frequency and high-frequency acoustic characteristics.: -

>The low frequencies have been enhanced with dual dynamic drivers and a 3D-printed Y-shaped structure, significantly improving bass elasticity and density.

>The addition of a micro planar driver to the high frequencies significantly improves treble extension and enhances overall sound accuracy.

>The acoustic structure and crossover circuit have been further refined, enhancing the overall sound coherence and texture.

*The direction of the damping is determined by the technical specifications. To maintain consistency in tuning, the damping direction may vary on the same pair of headphones. It could be installed in either the forward or reverse direction. Additionally, there may be differences in the damping material used for headphones of the same model but in different colors. These practices are all aimed at achieving consistent frequency response curves.

This is because our factory’s standard for headphone testing is much higher than the industry average. Before factory testing, we fine-tune the damping position to improve the symmetry of the headphone's frequency response curve. In the industry, as long as the left and right channels maintain a certain degree of deviation, products can be shipped. Therefore, their damping positions are typically fixed. However, before shipping, we make every effort to achieve symmetry, and thus, on the production line, there is a step to fine-tune the damping position in order to meet better technical standards
