Tanchjim OLA II HiFi Earbuds In-Ear Wired IEM Headphones with Mic (3.5 mm)

Why it's a great deal

• PURE Hi Ultra-High-Frequency BA Driver. PURE Hi is an independent BA driver designed to extend the ultra-high-fre-quency range while enhancing overtones and airiness. By reducing the load on the DMT 5 dynamic driver in the extreme treble region, the main diaphragm can focus more effectively on the lows, mids and core treble range. Working coaxially together, the two drivers create a more complete and co-herent sound.

• Harmonic Coherence. OLA ll places the DMT 5 dynamic driver and PURE Hi BA driver within a coaxial acoustic structure. Different frequency ranges enter the ear canal along a more closely aligned acoustic axis, reducing imaging shifts caused by differences in sound-source position and helping each frequency band arrive from a more coherent position. With a higher proportion of direct sound, imaging becomes more focused, treble is more precise, and vocals and instruments connect more naturally for a more balanced overall presentation.

• Balanced Geometry, Refined Precision. OLA ll continues the distinctive OLA design language, combining squared lines with soft curves. lts lightweight construction combines a precision CNC-machined aerospace-grade aluminum alloy faceplate with a transparent polycarbonate (PC) in-ear housing. The clear shell reveals the internal acoustic structure, while the lightweight design provides a comfortable fit even during extended listening.

• High-Performance Goertek MEMS Microphone, Clearer voice pickup for calls, meetings, and gaming. OLA ll is equipped with a high-performance MEMS microphone from Goertek. It captures your voice with improved clarity, making speech easier to hear during calls and voice chat. Whether you are in an online meeting, gaming with teammates, or taking everyday calls, your voice stays more present with less background noise.

• A Natural Fit for Long Listening. The housing of OLA ll has been refined using high-precision artificial ear data and more than 3,000 real ear-shape samples. From the nozzle angle and shell curvature to the support points and weight balance, every detail has been adjusted for a more secure and comfortable in-ear fit. Whether you are listening to music, gaming, or monitoring audio during a live stream, OLA ll is designed to stay comfortable through long sessions.
