TANCHJIM - OLA Wired IEM

A single dynamic driver IEM designed with lightweight and transparent PC cavities. The cavities have aerospace-grade aluminum covers creating an elegant design experience. The Tanchjim developed DMT4 Architecture Dynamic Loudspeaker independently that is configured in Tanchjim Ola. Tanchjim used FEM analysis and FEA finite element analysis software for tuning the drivers to make the sound natural and to give its clear presentation.

The aerospace-grade aluminum alloy cover made by precision CNC, equipped with ergonomic in-ear transparent PC cavity, fully fitting most people’s ear canal and providing non-fatiguing wearing. The pair simply looks exquisite and premium.

Tanchjim Acoustics R&D Department utilized the acoustic structure coupling (ASI) to analyze the inner cavity of IEM. After loading the geometric structure, the data such as the density of damping pores, cavity material and suspension system variables are controlled for FEM analysis and improvements. The reasonable inner cavity volume and design of OLA are obtained, which contributes to its excellent sound quality experience.

The front cavity of OLA is equipped with SATTI Filter imported from Italy, and the nano-Coating attached to the surface of the filter features dustproof and waterproof to enhance its durability.

OLA is highly fitted to the HRTF head-related transfer function curve, which brings clear imaging and hierarchical details, and ensuring the clear and realistic sound effects, percussion and footsteps during gaming.

OLA have a flat bass response, which is comparable to the objective index of the flagship HiFi in ear earphones, bringing a balanced and pleasant immersive listening experience. The cable has the strong toughness and can resist pulling to a certain extent. The skin is made of inert material, that make cable smooth and convenient to use.

The stock cable of OLA is twisted with double-core OFC core sandwiched with Kevlar fiber, and then covered with 4N OFC silver plated core for coaxial weaving. Due to its low capacitance, the outer silver-plated cable core does not participate in electric conduction, but only plays the role of suspension shielding. This gold-plated 0.78MM pin is designed to extend service life and is compatible with a variety of standard 2-Pin upgrade cables.
