TANCHJIM OLA II 1DD+1BA In-ear Headphone

TANCHJIM OLA II 1DD+1BA Hybrid IEM Overview

The TANCHJIM OLA II is a coaxial hybrid in-ear monitor built around two different driver technologies. It combines a 10mm DMT5 dual-magnetic, dual-chamber dynamic driver with a dedicated PURE Hi balanced armature, creating a 1DD + 1BA acoustic configuration.

TANCHJIM specifies a frequency response of 8Hz to 48kHz, 30Ω impedance, 121dB/Vrms sensitivity and total harmonic distortion of 0.03% at 1kHz and 94dB. The earphones also use a detachable 0.78mm 2-pin cable and are available with 3.5mm, 4.4mm balanced and DSP Type-C connection options.

10mm DMT5 Dynamic Driver + PURE Hi Balanced Armature

The OLA II uses TANCHJIM’s 10mm DMT5 dual-magnetic, dual-chamber dynamic driver together with a PURE Hi balanced armature. The hybrid arrangement allows the two drivers to work together within the same acoustic system instead of relying on a single driver for the entire frequency range.

Coaxial 1DD + 1BA Acoustic Architecture

The two drivers are integrated through a coaxial hybrid acoustic structure. This is one of the major differences between the OLA II and the original OLA, which used a single dynamic driver. The updated architecture gives TANCHJIM more control over different parts of the frequency range.

Low 0.03% Total Harmonic Distortion

TANCHJIM rates the OLA II at 0.03% total harmonic distortion at 1kHz and 94dB. Lower measured distortion means less unwanted harmonic content is introduced into the audio signal during playback.

8Hz–48kHz Frequency Response

The specified frequency response extends from 8Hz to 48kHz. Combined with the hybrid driver configuration, this gives the OLA II a technically capable foundation for listeners looking for a wired IEM with extended frequency coverage.

Detachable 0.78mm 2-Pin Cable

The OLA II uses standard 0.78mm 2-pin connectors rather than a permanently attached cable. This makes cable replacement easier and also allows users to switch to another compatible cable when needed.

The supplied cable uses a silver-plated Litz wire construction with a twisted structure according to TANCHJIM’s specification.

3.5mm, 4.4mm Balanced and DSP Type-C Options

TANCHJIM offers the OLA II with several connection options, allowing buyers to choose a version that matches their source device.

• 3.5mm: Suitable for compatible phones, laptops, dongles, DACs and amplifiers with a standard headphone output.
• 4.4mm Balanced: Intended for compatible DACs, headphone amplifiers and digital audio players with a 4.4mm balanced output.
• DSP Type-C: Connects directly to compatible USB Type-C devices and adds digital sound-processing features.

Device compatibility may vary, so buyers should check the available audio output on their phone, computer, DAC or music player before choosing a cable version.

8-Band PEQ Support on the DSP Version

The DSP Type-C version supports an 8-band parametric EQ through the TANCHJIM App. Users can adjust the sound according to their preference and access compatible sound presets through TANCHJIM’s software ecosystem. These DSP features apply specifically to the Type-C version.
