The Ola is the second budget IEM from Tanchjim after Tanya. It features aerospace-grade aluminium alloy covers connected to transparent resin shells. The Ola is equipped with a nano-coated SATTI nozzle filter that makes the pair dustproof and waterproof.
Tanchjim has equipped the Ola with the latest-gen DMT4 architecture dynamic driver unit on each side. Tanchjim Ola adopts FEM analysis and FEA finite element analysis software to simulate and analyze the driver with a large number of improvements such as optimizing the magnetic circuit, lowering the suspension quality, and adjusting the diaphragm rigidity.
Tanchijm Ola follows the HRTF (Head-Related Transfer Function) frequency curve.

Tanchjim has included a high-quality double-core OFC wire with Kevlar fibre covered with 4N OFC Silver-plated cable in a Litz coaxial structure. It has standard 3.5mm termination plug and 2-pin 0.78mm connectors. Users can also buy Tanchjim Ola with a Mic cable.

I would like to thank Hifigo for providing me with the review sample of Tanchjim OLA (no affiliate link).

The cable is very good (to my taste). It’s soft, has no microphonics and has beautiful colour matching metal connectors on both sides.
I solved the problem with IKKO foam tips. The foam material is amazing, they are shorter in length which helps to keep the sound as it is, they are kinda sticky on the outside too, they fit and secure perfectly. Finally.
Another potential problem that you might have is the sharp corners of the shell. You see my ears are not equal in size, no problem with the left ear but I have a problem in the right ear with sharp edges because it touches my outer ear and starts to hurt after a while. Foam tips seem also solve this problem for me.
Tanchjim Ola definitely is a very unique and technical IEM with very enjoyable tonality and overall sound performance. For under 50$ I don’t know any other contender, yet. BUT the fit issues-lack of isolation can be a BIG problem for some. It can be a hit or miss depending on your ear structure, I must add.
