The Bellos Audio X-Series IEM is designed to give you a next-level sound experience with comfort and durability that very few IEMs in the same price point can match.
Experience pressure-free listening with In-Air Canals and ATOM Venting and get reliable comfort with RCX Cables and 3D Printed Matte Shells.
Available in three driver configurations, X-Series IEMs offer thoughtful customization options so you can build the perfect in-ear monitor for your needs.
The Bellos Audio X-Series comes with innovative features for elevated sound, comfort, and durability:
The 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 Bellos Audio X-Series IEMs.
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.
All three X-Series variants come with Bellos 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.
IEM connectors and cables are the most common points of failure in any in-ear monitor system. 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.
Each X-Series IEM is built through 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.
Custom-molded IEMs can take weeks or even months to build - not the X-Series IEMs.
The 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.
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.
The Bellos Audio X-Series is a premium universal hybrid IEM from 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)

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.
Unexpected as in very pleasantly surprised at the sound quality coming out of these :)
I took my Mega5-EST and hooked em up wirelessly and don't miss the wire sound AT ALL!! IMO the wireless sound was 98% of the wired sound without the PIA of the wire. Unless you have some amazing source gear, which thanks to Adam at hifisoundgear I do, you would be hard pressed to hear a massive difference. Especially with a phone as your source.
I did A/B noble Fokus Prestige vs Go pod w Mega 5 and gotta say l, there is more balanced sound with the Go pod chain then the Prestige on its own. To be fair the Mega 5 punches WAY above its price... so the 2 are a match made in heaven.
I find the connection very stable as well. I've used my iPhone AAC/SBC as well as with FiiO BT11 to get other than Apple codecs and was pleasantly surprised as well.
The ear hooks are very comfortable. Actually prefer them to the wire hanging over my ear with a tie behind my neck. For some reason that's hard to get used to and pulls as I wear loose shirts. The hooks stay in as I like to move around a bit. Also the weight is better distributed than other wireless IEMs as the components are in the hooks. The prestige, unless I have foam tips, which I'm not a fan of, will pop out of my ears when I move around. These stay stable and I do not have to re-seat the IEMs to get that great bass nearly as often with other wireless IEMs.
Battery level has been all day 10 hrs so far with intermittent breaks and still have 28% left.
The case also is deep enough to fit the Mega w hooks as it charges which is very convenient. Some IEMs may be too big but they fit with a tad bit of room to spare.
Of course having the flexibility to swap out your favorite IEMs as needed is awesome!!
5 stars for the Go pod and more importantly 5 stars to Adam and his team for such amazingly awesome customer service!! You guys ROCK!! Thanks :)
The iFi Audio iDSD Diablo 2 is an absolute masterpiece in the world of portable amps. It delivers an audio experience that redefines what’s possible in a compact, travel-friendly device.
To all the "haters" out there who mention that the 5180mw output is an overstatement and the "balanced" is not a true balanced output... I say whatever... it drives anything I throw at it with aplomb! FostexTH900mk2, ZMF Caldera Open and Closed, ANY IEM my friends and I have tried ...too many to list. If you need more power than this portable titan.... well you may have hearing loss. And it drives all I mentioned without using "beast mode" (they refer to it as Nitro (1 of 3 settings)). If anything, it could use a lower gain option / IEM match for some sensitive IEMs.
The implementation of BT 5.4 (supports all codecs) is a welcomed addition for quality, but in general, the distance it can be from the source is very small for consistency. That is not a Diablo issue, but a BT5.4 issue IMO.
As for the sound quality...simply unparalleled. I have compared this to desktop headphone amps in the same price range and I would put it toe to toe with them. It even ran close to my buddy's Burson Soloist 3x!!! and the Diablo 2 is portable :)
I run it using A&K SP3000T and it oozes warmth and richness in the lows and highs WITHOUT covering/smoothing anything up in the mids, which is my jam.
It is on the heavier side and will still fit in a pocket... barely. built like a brick. At the limit of what I would like to carry but totally worth it! I get about 6 hours of the 8 rated battery with constant listening, no Bluetooth on, hard wired, IEMs / Caldera tested on the battery life.
In conclusion, the iFi Audio iDSD Diablo 2 is nothing short of extraordinary. It’s the ultimate portable amp for those who refuse to compromise on sound quality, power, or versatility. If you’re serious about your audio and want the best experience on the go, the Diablo 2 is the perfect choice.
Shout out to Adam, a massive THANK YOU!!! for your absolutely OVER THE TOP customer service and shopping experience :) :) Seriously, your dedication and attention to detail have been nothing short of exceptional.
With all the online ordering over the years, HifiSoundGear provides the best service I have encountered. It was as though they were good friends. They responded so nicely to all my questions about the product and shipment. As it works out, while I liked the IEM's, I concluded they were not sufficiently different from the ones i had been using. Again, for the process of returning and getting a refund, they could not have been nicer. Buying from them was a first rate experience.
Recently had a great experience with Adam and Laura. I requested a price match for the FiR KR5 and it was such a painless process. Adam and Laura’s communication is top notch! Adam even sent me a personal thank you video. In my experience, this level of service is hard to come by these days. I highly recommend going through HifiSoundgear for your audio needs….I know I will be going forward! Thanks Adam and Laura!
The quality of service, level of help provided, and overall customer satisfaction is beyond anything I have experienced. I cannot say enough good things about the people who belong to this company!
As for the U4S, these are my first foray into 64 Audio but I am SO thankful that I got to experience them! My goodness the soundstage, bass response from the m15 module, and overall quality is just great!
Please, buy from these wonderful people! And if you can swing it, get a set of U4S! You will not regret it!
Only complaint is the cable. For the price, I expected better, but it works well and is just fine.
Thank you HiFi Sound Gear! I look forward to purchasing more from you in the future!
These are the closest TWS gets to pure IEM listening. You get the wide soundstage. They scale quickly. They have that satisfying bass slam often missing in TWS. The layering is just right and resolution is mesmerizing. Oh yes, you get the convenience of taking them on the go and they are truly comfortable. Noble has achieved a superior status in my eyes with the FoKus Prestige. I look forward to listening to them on my walks when I don’t have to take my DAP. Adam is one of the greats in this business. His commitment to customer service is exceptional. You aren’t a customer, but a client. He helped me after losing my first pair and just went above and beyond to ensure that I was shipped a new pair in less than two days. I am completely satisfied and impressed. You will be too. Thank you and looking forward to my future purchases from your establishment.
HifiSoundGear offers exceptional quality products and unparalleled customer service. Their wide selection of high-end audio gear, including in-ear monitors and amplifiers, are praised for delivering outstanding sound clarity, detail, and an immersive listening...
