FiR/Bellos Audio X-Series IEM Features

The FiR/Bellos Audio X-Series comes with innovative features for elevated sound, comfort, and durability:

  • In-Air Canal Technology
  • 3D Printed Matte Finish Shell
  • ATOM Venting Technology
  • RCX Cable & Connector

Three Drivers Your Choice - X-Series Modular Drivers

The FiR/Bellos Audio X-Series IEM comes in three unique driver configurations, each boasting unique sound capabilities. Choose between the X2 (two BA drivers), X3 (one Dynamic Driver and two BA), and X4 (one dynamic driver + 2BA) and experience your preferred sound.

Pick the X2 with its twin BA drivers tuned to deliver a mid-centric sound with great instrument separation, or choose the X3, which features a similar tuning to the X2 but with extra low-end energy brought by the 6mm dynamic driver.

If you want the best sound possible, the X4 is the one to get. Its 6mm dynamic driver and three BA drivers are tuned to deliver unmatched detail, clarity, and immersion.

Experience next-level sound no matter which variant you go for with the FiR/Bellos Audio X-Series IEMs.

Consistent Sound No Matter What - In-Air Canals Technology

All X-Series IEMs come with the innovative In-Air Canals Technology for enhanced fit and comfort.

By perfectly sealing the entrance of the ear canal, the Bellos Audio X-Series ensures you hear nothing but your favorite tunes. This ultimately enhances immersion and sound quality, allowing you to hear your music without any distractions.

Listen For Longer - FiR/Bellos Audio X-Series ATOM Venting

All three X-Series variants come with FiR Audio's ATOM Venting technology for unbeatable comfort and soundstage performance.

Without optimal venting, IEMs will eventually feel uncomfortable to wear due to pressure buildup. ATOM Venting not only vents out extra air for enhanced comfort but also extends the soundstage for a more realistic sound.

Lasting Connections - FiR/Bellos Audio X-Series RCX Cables

IEM connectors and cables are the most common points of failure in any in-ear monitor system. FiR/Bellos Audio addresses this issue through their proprietary RCX Connector/Cable.

Swap cables without worry with the X-Series RCX Connector/Cable. Rated for up to 5000 connections, the RCX Connector/Cable ensures you get reliable performance onstage or in the studio.

Paired with the X-Series' impressive 2-year warranty, you're guaranteed to get a worry-free monitoring experience for years to come.

Precision and Comfort - 3D Printed Matte Shells

Each X-Series IEM is built through FiR/Bellos Audio's patented 3D Printing technology for accurate fit and comfort. The shells are built using soft-touch matte material for secure grip and a soft feel.

Enjoy a soft, smooth feel with comfort that disappears in your ears with the X-Series IEMs.

No More Waiting Around - Short-Build Time for X-Series IEMs

Custom-molded IEMs can take weeks or even months to build - not the X-Series IEMs.

The FiR/Bellos Audio X-Series IEMs offer a brisk 5-day build time (after receiving usable ear impressions), making it one of the easiest custom IEMs to get.

Choose your preferred model, color, and cable, send in your ear impressions, and get your very own X-Series IEMs in a matter of days.

FiR/Bellos Audio X-Series Frequency Response

The X-Series IEM covers frequencies from 20hz to 20kHz (18kHz for the X2 and X3) - allowing for a wide range of frequencies to be reproduced accurately.

FiR/Bellos Audio X-Series Price

The FiR/Bellos Audio X-Series is a premium universal hybrid IEM from FiR/Bellos Audio. The X2 starts at $499, while the X3 costs $799. The top of the line X4 model will set you back $999.

Ordering Process:

At HiFiSoundGear, we understand that the journey to perfect audio is unique for every individual. We also understand that the custom IEM ordering process can be confusing at times. That's why our custom IEM ordering process is designed to be as seamless and supportive as possible. 

Here's how we do it:

1) Choose your custom IEM model, add to cart, and proceed through checkout. This authorizes payment for the base IEM, and gets the ordering process started.

2) We'll reach out with an order confirmation and send you a form with instructions on choosing your custom options. You can fill out the form yourself, or contact us by phone or email. We're happy to fill in the options for you - just let us know what you're looking for!

3) If you've chosen any options that have an extra cost associated with them, we'll handle it at this point of the process with an invoice. (Custom artwork, wood faceplates, etc.)

4) We'll find a few audiologists in your area and work on helping you get an appointment set for your impressions! All you need to do is show up. We'll provide you with a special guide and instructions for your audiologist.

5) Send us pictures of your impressions so that we can verify whether they can be used for production. This prevents the headache of shipping your impressions only to find that they are not detailed enough.

6) We'll send you a shipping label and a confirmation sheet for your impressions, marked and addressed to the right place.

7) We'll confirm that your impressions have been received, and that the production of your custom IEMs has begun! Expect to wait 4-6 weeks for production and final shipment. (Bellos Audio X-Series are 1-week production time)

As always, we're available to help at any point of the process. Just reach out by phone at (888) 926-8024 or by e-mail at info@hifisoundgear.com.

 

Returns

Refunds, returns, and exchanges are NOT available for custom IEMs after your order has been submitted and production has started, due to the highly custom nature of the product.
