Premium 4BA In-Ear Monitor

The O400 project began when we began product review of the O800. The aim of the project was to achieve the high-resolution and highly dynamic sound that is the hallmark of our new O-Series through a reference class IEM in a more affordable price segment. To achieve this, we used the know-how we gained during the development of our flagship O800 for the O400.


  • Handmade resin headphone case;
  • 4 BA driver technology;
  • Handmade Class 8 Wires (Silver Plated Copper) Braided Detachable Cable;
  • Perfect natural and balanced sound;

Lively sound with high dynamics

As the development of the O800 was extended, the development of the O400 was sufficiently mature, and as a result, it implemented a high-resolution, high-density sound with perfect balance and a sense of dynamics. The sound of the O400 is so natural that it brings the music close to the listener and makes them forget that they are listening to it through IEMs. You have the same feeling as if you were listening to the recording in a large studio.


Of the four BA drivers used in the O400, three are from Knowles and one was developed using our technology based on experience with the O800 drivers. All drivers in the O400 have been carefully selected, developed and tested, and the combination of new drivers and Knowles drivers ensure perfect reproduction of low, mid-low, mid-high and high frequencies.


The O400 uses an innovative four-way crossover network. Thanks to a fine micro design, the crossover of the O400 perfectly implements the sound we intended.


The O400 case is based on the new O800 case shape. It is finely handcrafted by qualified engineers.


The Oriveti 8 Wires silver plated copper wires are made of high quality low impedance wires to avoid cable losses.
We used 0.78mm 2 pin connectors, which are more durable and universal than MMCX.

AZLA SednaEarfit™ Xelastec

In addition to the Bullet Shape Eartip, Bowl Shape Eartip, Double Flange Eartip and Formtip, we offer AZ'LA's SednaEarfit™ Xelastec Eartips.
