ORIVETI O400
Premium 4 BA HiFi IEM Earphones

The O400 project began when we started reviewing the O800 product inspection. The goal of the project was to make the high-resolution and dynamic sound, which characterizes the sound of our new O series, more accessible through a reference-class IEM at a more affordable price. For this, we utilized the know-how accumulated during the development of our flagship O800 for the O400.

ELEVEN SOUND WITH GREAT DYNAMICS
Since the development of the O800 was delayed, the development of the O400 reached maturity, and as a result, it created a sound with high resolution, high density, perfect balance, and dynamics. The sound of the O400 is so natural that it expresses music very closely to the listeners and makes them forget that they are hearing it through IEMs. It offers the same level of immersion as listening to the recording in a large studio.

EXCEPTIONAL QUALITY 4 BA DRIVER
Out of the four BA drivers used in the O400, three are from Knowles, and one is customized using our own technology based on the design experience of the O800 drivers. All drivers in the O400 are carefully selected, designed, and scrutinized, and the combination of new proprietary drivers and Knowles drivers perfectly reproduces ultra-low, medium-low, medium-high, and high sounds.
APPROPRIATE CROSSOVER
The O400 used an innovative four-way crossover. Through fine micro-tuning, the O400's crossover perfectly achieves the desired sound.

HANDMADE RESIN HOUSE
The O400 case is based on the new design of the O800. It is made with fine, handcrafted artisan work by skilled engineers.

HANDMADE 8TH GRADE WIRED BRAIDED SPC CABLE
The silver-plated Oriveti 8 Wires copper wire is made from high-quality, low-impedance wires to prevent losses caused by cables.
We used a 0.78 mm 2-pin connector, which is more durable and more common than the MMCX.
