DMT 5 Coaxial Hybrid Driver Structure | PUREHI High-Frequency Balanced Armature Driver | Equipped with DSP-MASTER
DMT 5 Dual-Magnetic Circuit Dual-Cavity Dynamic Driver
The OLA II features a 10mm DMT 5 dual-magnetic circuit dual-cavity dynamic driver handling the entire frequency range, providing ample magnetic flux and precise control for smoother driving and lower distortion, achieving 0.03%@1kHz 94dB. The driver diaphragm was also retuned specifically for the OLA II after multiple adjustments and stress distribution analyses. The dual-cavity structure effectively controls airflow and resonance, resulting in an exceptionally pure black background and excellent transient response, achieving balanced and harmonious frequency response and a rich, three-dimensional musical performance.
PURE HI Ultra-High-Frequency Balanced Armature Driver
The balanced armature driver utilizes the PURE HI ultra-high-frequency balanced armature driver. The ultra-high frequency range of the OLA II is processed by the PURE HI ultra-high-frequency balanced armature driver after crossover. Because the ultra-high frequency range is handled independently by a dedicated tweeter, the OLA II excels in ultra-high frequency extension, overtones, and airiness.
Coaxial Sound Structure and Special Chamber Design
OLA II's DMT 5 dynamic driver and PURE Hi balanced armature driver are housed in a coaxial sound structure. Different frequency bands enter the ear canal along the same axis, reducing imaging shift at the sound source location. This results in a more focused listening experience, with vocals and instruments appearing more coherent and harmonious. Furthermore, the OLA II's internal chamber has been specially treated to increase its smoothness, providing a better sound transmission path and resulting in a cleaner, crisper sound that highlights musical details.
Ergonomic Design and Litz Structure
The OLA II's chamber shape was designed and tuned based on data from over 3000 ears. Combined with an external pressure relief structure, it balances the pressure within the user's ear and improves comfort. Therefore, the entire design ensures user comfort during extended wear. In addition, the OLA II features a Litz copper silver-plated twisted-pair braided cable, which effectively reduces interference and high-frequency loss, resulting in more stable performance and higher anti-interference capabilities.
TANCHJIM App：8-band PEQ
The OLA II DSP Type-C version supports 8-band PEQ adjustment and post-production sound tuning via the TANCHJIM App. Users can adjust the EQ according to their preferences and usage needs in different scenarios.
Built-in Decoding Chip
The OLA II DSP Type-C version features a built-in decoding chip, supporting 384kHz and 32-bit audio, offering stronger analytical capabilities and revealing more detail and clarity in sound and music.
