Exceptional High-Resolution Audio in an Ultra-Comfortable Design
The Tanchjim OLA II marks a massive leap forward from the highly acclaimed original OLA. Upgraded to a powerful hybrid configuration, the OLA II combines a next-generation 10mm DMT5 dynamic driver with a custom-engineered Pure Hi ultra-high-frequency balanced armature driver. By aligning both drivers along a precise coaxial acoustic axis, Tanchjim delivers an incredibly cohesive, rich, and detailed soundstage with crisp transient response and zero phase interference. Wrapped in a sleek, lightweight, and dustproof chassis, the OLA II delivers professional audiophile performance in a shell designed to comfortable fit any ear.

Dual-Driver Coaxial Hybrid System
The OLA II features a highly advanced hybrid driver configuration. A custom-developed Pure Hi balanced armature handles the ultra-high frequencies, adding incredible air, sparkle, and natural overtone extensions to your tracks. By offloading the extreme treble load to the BA, the main dynamic driver is free to focus strictly on delivering deep, snappy bass and beautifully lush midranges.

Next-Generation DMT5 Dynamic Driver
At the heart of the OLA II is Tanchjim's proprietary 10mm DMT5 dual-magnetic-circuit, dual-chamber dynamic driver. This structural design maximizes the magnetic flux density inside the voice coil, allowing the diaphragm to move with lightning-fast transient response and incredibly low distortion. Bass hits with tactile authority and precise texture without muddying the vocal ranges.

Aerospace-Grade Aluminum and Ergonomic Design
Built with premium, CNC-machined aerospace-grade aluminum alloy faceplates and transparent medical-grade PC inner cavities, the OLA II looks as stunning as it sounds. The ergonomic shell shape was sculpted after analyzing physical ear profiles, ensuring a pressure-free, incredibly secure fit for hours of comfortable listening.

Built-In Dust and Waterproof Protection
Perfect for outdoor commuting, workouts, or daily travel, the OLA II comes equipped with Tanchjim's specialty waterproof and dustproof nozzle filters. This protective mesh shields the internal hybrid drivers from moisture and debris, preserving the acoustic pathways for long-term performance.

High-Purity Silver-Plated Litz Cable
To guarantee clean signal transmission without coloration, the OLA II includes a premium, detachable silver-plated copper Litz cable in a twisted structure. Using standard 0.78mm 2-pin connectors, this cable is highly flexible, tangle-resistant, and easily upgradeable.
