TANCHJIM OLA II 1DD+1BA Hybrid In-Ear Monitor
The TANCHJIM OLA II is a wired hybrid in-ear monitor built for listeners who want detailed, balanced sound without a complicated setup. It pairs a 10mm DMT5 dynamic driver with a PURE Hi balanced armature in a coaxial 1DD+1BA configuration, giving you punchy bass alongside clear mids and extended treble in a single, cohesive sound signature.
What sets the OLA II apart is its dual-magnetic, dual-chamber dynamic driver design, engineered to reduce distortion and improve control across the frequency range. With a frequency response of 8Hz–48kHz and total harmonic distortion as low as 0.03%, the earphone is tuned for accuracy whether you're listening to vocals, instrumentals, or bass-heavy tracks.
The OLA II also includes an 8-band PEQ through the TANCHJIM app, so you can fine-tune the sound to match your preference or your source device. Combined with a detachable silver-plated Litz cable and multiple connection options, it's a flexible hybrid IEM for everyday listening, critical listening sessions, or on-the-go use.

Why Choose the TANCHJIM OLA II Hybrid In-Ear Monitor
