X4
We are excited to introduce the X4, our flagship X-Series of custom in-ear monitors. The X4 is the culmination of our commitment to providing an exceptional sound experience for musicians and audiophiles alike. With an additional ultra-high driver and our proprietary In-Air Canal technology, the X4 delivers unprecedented levels of clarity, detail and realism.
The X4's tuning is finely tuned to deliver a warm sound signature that reveals every subtle detail of your music. The ultra-high driver provides an extended frequency response and delivers a very smooth and natural sound. The In-Air Canal technology enables the most comfortable CIEM listening experience. So comfortable that you feel like you have nothing in your ears! The X4 are the best in-ear monitors in their class and the perfect choice for those who demand the highest audio quality.
Like all X-Series models, they feature a variety of additional technologies such as ATOM Venting which significantly increases the soundstage, beautiful 3D printed matte cabinets, the ultra-durable RCX cable connector, modular drivers and removable front panels for quick and easy maintenance and repairs.

"The Bellos Audio X4 is smooth sounding and yet enjoyably rhythmic at the same time making it a very nice matchup for modern pop and soul vocal performances. Nothing is overly fatiguing in its delivery."
Bellos Audio X4 Review — Headfonics

Bellos Audio X4 Review - Headfonia Reviews
"Perfectionistic expectations aside, when it comes to very well made value for money professional grade CIEMs with very easy to like sound signatures, there is little to fault in the Bellos IEMs, with the build and convenience of quick delivery being exceptional. If you can afford the $999 X4, that's the one I'd recommend going with. It sure is their best one."

technologies
Our proprietary technologies that enable us to produce best-in-class custom in-ear monitors.
in-air ducts
If you've ever used custom IEMs, you'll know that when you open your jaw to sing or speak, your ear canals deform. As a result, the CIEMs lose their seal and feel uncomfortable in the ear. Introducing the revolutionary In-Air Canal technology. A patented design that allows a complete seal at the opening (entrance) of the ear canal. It offers all the benefits of CIEMs without their drawbacks. They're so comfortable, you'll forget you have them in!
ATOM ventilation
A pressure relief system that disperses air pressure that builds up in a sealed ear canal. This increases the sound image and greatly reduces listener fatigue, so you can hear more and listen for longer. You no longer feel cut off from your surroundings.
3D printed mat Housing
Using our patented 3D printing technology, we design the Custom In-Ear Monitors in 3D software with nanometer precision. The parts are printed and efficiently assembled by hand. Shortly after, the matte finish is applied to the CIEM shell to ensure a very comfortable and organic fit with a "grippy" consistent seal.
RCX cable
One of the most common sources of failure is the cable. Our proprietary RCX cable changes this. The only cable connection specifically designed for Custom In-Ear Monitors. It is rated for 5,000 connections without failure. The RCX cable comes with our standard 2-year CIEM warranty.
Removable faceplates
A revolution in custom in-ear monitor design. A traditional custom IEM must be cut open to be repaired. Our design features a front panel that is attached with alloy steel screws, allowing us to repair custom in-ear monitors quickly and efficiently.
Modular drivers
The CIEM enclosure is designed to accommodate a pre-assembled driver package that is tested in advance to ensure it meets all specifications. Modular drivers can be installed and removed without damaging or destroying the CIEM enclosure.
