TANCHJIM OLA II 1DD+1BA In-ear Headphone

TANCHJIM OLA II 1DD+1BA In-Ear Monitors Overview

I’ve been selling audiophile gear and tech accessories in Dhaka for 7 years, and I can tell you the budget IEM (in-ear monitor) market is more competitive than ever. When the original Tanchjim OLA dropped, it was a massive hit, but people wanted a bit more treble extension and a fuller low-end. Tanchjim listened. They completely redesigned the architecture and released the TANCHJIM OLA II 1DD+1BA In-ear Headphone, and we made sure to get it on the shelves at Gadget Breeze immediately.

This isn’t just a minor refresh. Tanchjim upgraded from a single dynamic driver to a coaxial hybrid setup. It now features a 10mm DMT5 dual-magnetic dynamic driver handling the punchy bass and warm mids, paired with a dedicated PURE-Hi balanced armature that takes care of the ultra-high frequencies. The result is a sound that punches way above its price bracket—offering incredible clarity, precise imaging, and zero muddiness even when listening to fast-paced rock or heavy metal.

The Shop Floor Reality Check: Why We Recommend the OLA II

We test a lot of earphones at our counter, and specs only tell half the story. Here is my honest, hands-on breakdown of why the OLA II stands out from the sea of budget IEMs:

• Zero “Cheap BA” Harshness: A lot of budget hybrid IEMs sound harsh or metallic in the treble because of cheap balanced armatures. Tanchjim tuned the PURE-Hi BA driver perfectly. You get beautiful sparkle and airiness in female vocals and cymbals without any ear-piercing sibilance at high volumes.
• Incredible Build Quality: These look and feel like premium monitors. The faceplates are CNC-machined from aerospace-grade aluminum, while the inner cavity is a transparent resin that lets you see the drivers inside. Plus, they are extremely lightweight and ergonomically shaped, so you can wear them for hours without ear fatigue.
• Ultra-Low Distortion: Because they separated the highs into a dedicated BA driver, the dynamic driver doesn’t have to work as hard. This drops the Total Harmonic Distortion (THD) down to an insane 0.03% at 1 kHz. Music sounds incredibly clean and separated.
• Three Connection Options: We love that they offer choices. You can get a standard 3.5 mm (with a mic) for normal use, a 4.4 mm balanced version for your audiophile DAP, or the brilliant DSP Type-C version that plugs straight into modern phones and features a built-in DAC with customizable 8-band EQ through their app.
• Easy to Drive: You don’t need to buy an expensive, heavy portable amplifier to make these sound good. At 30Ω impedance and 121 dB sensitivity, they get plenty loud and dynamic straight out of a standard smartphone headphone jack or a basic Type-C dongle.

Real Questions Customers Ask Us (FAQ)

1. Which cable version should I actually buy?

If you use an older phone or laptop with a headphone jack and want to take calls, get the 3.5mm version. If you are a serious audiophile plugging into a dedicated digital audio player (DAP) or high-end amp, buy the 4.4mm balanced version. If you have a modern Android or iPhone 15/16 without a headphone jack, the DSP Type-C version is the smartest choice because it has a built-in DAC.

2. Does the Type-C version need a separate dongle DAC?

No! The DSP Type-C version actually has a high-quality Digital-to-Analog Converter (DAC) built right into the plug. It decodes high-res audio at 384kHz/32-bit natively, so you just plug it straight into your phone and hit play.

3. Can I change the cable if it breaks?

Yes. The OLA II uses industry-standard 0.78mm 2-pin connectors. If your dog chews the cable or you eventually want to upgrade to a pure silver cable, you can simply pull the old cable out of the earbuds and snap a new one in.

4. Will these fit comfortably in small ears?

Tanchjim is famous for ergonomic designs. They analyzed over 3,000 ear shapes to design this shell. The rounded-square faceplate and curved inner resin cavity sit very flush against the ear. Combined with how lightweight the aluminum is, they fit beautifully even in smaller ears without causing pressure points.

5. Can I use the OLA II for competitive gaming like PUBG or Valorant?

Yes. Because it uses a hybrid setup, the BA driver provides excellent high-frequency detail and instrument separation. This means you will have very clear directional audio for hearing footsteps and reloads. Plus, the 3.5mm and Type-C versions come with a great in-line mic for squad chat.
