Nothing can beat custom IEMs when it comes to comfort and fit. Unlike mainstream universal IEMs built around a generic shell design, custom in-ear monitors are molded according to your unique ear shape, which results in improved comfort, noise isolation, durability, and sound for an infinitely superior listening experience.
Our collection of custom IEMs features some of the best custom in-ear monitors in the market right now. Browse through premium custom IEMs from 64Audio and FiR Audio and buy the right IEMs for your needs.
Like universal IEMs, custom in-ear monitors offer various tuning options and sound signatures to suit artists or audiophiles alike. When choosing your custom IEM, consider build time, driver configuration, and tuning for the best results.
Universal IEMs and Custom IEMs of the same make and model typically employ a similar driver setup and tech package. The main difference is that custom IEMs are custom-built and boast a fit that trumps even the most comfortable universal in-ear monitors.
The materials used for custom IEM shells are pretty similar between manufacturers. Typically, audio brands will use medical-grade resin material for the shell and combine it with a custom faceplate. Build time will vary between manufacturers, but expect to wait at least a few weeks to get your custom IEMs.
Another factor to consider is driver count and tuning. You’ll find custom in-ear monitors with as few as two drivers up to crazy 18-driver solutions. In terms of tuning, custom IEMs offer various flavors to suit every type of listener. There are bassy audiophile-friendly IEMs for personal listening as well as studio-reference-grade tuned IEMs for studio or onstage use.
Custom-molded in-ear monitors offer an unbeatable combination of sound, comfort, and durability, making them the superior type of IEM for both personal or professional use.
Built using an accurate impression of your ear’s unique anatomy, custom-molded IEMs offer a glove-like fit that disappears in your ear, resulting in comfort and fit you won’t get with universal in-ear monitors. Sound is improved as well, thanks to the superior fit and noise isolation, and durability is a step above due to more stringent quality control.
Premium features come at a premium price, so expect to pay extra for custom-molded in-ear monitors. When it is all said and done, custom in-ear monitors will be well worth your money, as you’re getting unbeatable quality, sound, and comfort by going with custom-molded IEM.
At HiFiSoundGear, getting Custom IEMs has never been easier. Just choose your preferred CIEM, proceed through checkout, and we’ll reach out to you with instructions on choosing your custom options. We’ll help you find audiologists in your area so you can get your impressions done as soon as possible.
Depending on the manufacturer, Custom IEM build times typically take a couple of days to several weeks. The sooner you get your impressions done, the faster you can enjoy your shiny new Custom IEM.
Explore the wide range of Custom IEMs from HiFiSoundGear. Proceed to checkout with your preferred CIEM model, and we’ll handle the rest.

The 64Audio A18t is an 18-driver custom IEM with a warm-neutral tuning perfect for onstage or studio use.
The A18t features a multi-driver Balanced Armature driver setup. Eight BA drivers handle the bass, while another eight drive the mids. There's a BA driver for high-mid and a Tia high driver to handle the ultra-high frequencies.
The overall sound signature of the A18t is warm neutral - a type of tuning that gives instruments and vocals outstanding weight, impact, and power.
Bass on the A18t reaches effortlessly into the sub-bass regions and rumbles with shocking detail. The impressive sub-bass performance extends to the mid-bass, giving it a nice natural-sounding punch.
The midrange on the A18t is ultra-clear, detailed, and well-separated. The mid-bass lift enhances male vocals for extra power and impact, while female vocals get good body and weight from the low-end emphasis. As expected from a warm-ish midrange, instruments sound wonderful on the A18t. Bass guitars sound nice and thick, while drums and percussions sound impactful and natural.
The treble on the A18t sounds smooth yet sparkly. The Tia high driver works its magic here - it extends the A18t’s treble without sounding harsh or thin. Female voices extend effortlessly without losing their natural tone and body, while cymbals and other high-frequency sounds remain smooth.
On to comfort and fit, the A18t offers exceptional fit and comfort, thanks to the ultra-accurate 3D printed shells and comfort-enhancing Apex Modules. The 64Audio A18t’s shape is molded according to the user’s ear, fit and comfort will never be an issue.

FiR Audio’s Radon 6 is an IEM created to commemorate the 5th anniversary of FiR Audio. With only 300 units released, the FiR Audio Radon 6 is an ultra-rare IEM offering a unique set of technologies and a sound signature you won’t find anywhere else.
The Radon 6 is a six-driver IEM featuring one “Kinetic Bass” 10mm dynamic driver for the bass, two Balanced Armature drivers for the mids, one BA driver for the high-mid, and an electrostatic driver for the ultra-high frequencies.
You get two build options for the Rn6 - a universal option with a beautiful metal build and a highly customizable custom-molded option. Both options feature FiR Audio’s ATOM Modules and the Kinetic Bass 10mm driver.
On to the sound, the FiR Audio Rn6’s sound signature is detailed and engaging. Tuning is bass-centric but with great extension in the higher frequencies for a detailed and sparkly sound.
Bass is the most impressive thing about the Radon 6. The 10mm dynamic driver pumps sound and vibrations directly into your ear lobes, delivering bass you can feel. There’s enough quantity to satisfy bass heads, but the bass presentation is impressively fast and well-controlled.
The mids on the RN6 are exceptionally natural. Male and female voices come through with satisfying weight and tone, while instruments like guitars are presented with detail and clarity.
The treble on the FiR Audio Radon 6 is well-extended and effortlessly adds sparkle and air to any music. The treble extension is so generous it verges on sounding too exciting. The Rn6 delivers eye-opening detail at the highest end, which is exciting but can be fatiguing after some time.
Overall, the FiR Audio Radon 6 delivers an ultra-detailed listening experience that’s perfect for audiophiles chasing ultimate detail and resolution from their music.

The 64Audio N8 is a signature custom IEM built for the legendary bassist and vocalist Nathan East. 64Audio tuned the N8 according to Nathan East’s inputs, you can be sure the N8 will deliver the best custom IEM experience for bass players and bass lovers.
The N8 is a custom-molded, 9-driver hybrid IEM with one 9mm dynamic driver for the bass, six Balanced Armature drivers for the mids, one Balanced Armature driver for the high-mid, and a Tia high driver for the ultra-high frequencies.
As you would expect from an IEM built for a legendary bassist, the N8 delivers a smooth, warm, and thick sound signature - perfect for reproducing bass notes.
Bass on the N8 is best described as organic, natural, and powerful. The N8 reaches deep into the sub-bass and delivers sub-bass notes with a satisfying rumble. The mid-bass slams with authority and power. The presentation here is thick and weighty, but there’s a satisfyingly organic feel with how the notes arrive and disappear.
Despite the substantial bass response, the mids on the N8 are tuned a bit leaner - likely meant to add detail and texture to higher-end notes on the bass guitar. Still, the tuning is great here, and the notes sound accurate and organic.
The upper mids and treble on the N8 are smooth and natural. You won’t get sparkly highs here, but the Tia high driver delivers just enough extension to keep notes sounding clear and detailed.
As mentioned, the 64Audio N8 is custom-molded only, so expect an outstanding fit out of the box. You can customize the N8’s shell color, faceplates, and logo design to suit your preferences, and you also have the option of swapping out the Apex Modules to alter the sound to your liking.

Drummers need a great-sounding IEM that’s comfortable yet durable enough to withstand onstage abuse. The FiR/Bellos Audio X4 IEM is a strong candidate for the job.
The X4 is the top dog of the X-Series IEMs from FiR/Bellos Audio. It features a quad-driver setup with one 6mm dynamic driver for the sub-bass, two Balanced Armature drivers for the bass, mids, and highs, and a dedicated Balanced Armature driver for the ultra-high frequencies.
The FiR/Bellos Audio X4 is custom-molded using a matte-finished polymer material for a grippy and comfortable on-ear feel. To enhance comfort even further, the FiR/Bellos X4 features a slew of comfort-centric technologies like ATOM Venting for reduced ear canal pressure, and improved seal through FiR/Bellos Audio’s unique In-Ear Canal technology.
In terms of sound, the X4 delivers a warm-reference tuning - perfect for drummers, bassists, and audiophiles looking for a bassier sound signature.
The bass on the FiR/Bellos Audio X4 is great. The dynamic driver delivers a satisfying slam and impact characteristic of well-tuned dynamic drivers. The bass presentation is tuned to deliver more mid-bass, but there’s enough sub-bass presence to deliver a satisfying rumble.
The midrange on the FiR/Bellos X4 is tuned to sound natural. A warm tinge in the midrange gives vocals and instruments a full and weighty sound. The balanced tuning places sound towards the front of the mix for a more intimate and detailed presentation.
The treble on the X4 is well-extended, which means high-frequency sounds can be a bit too energetic. Still, there’s enough control to keep things from sounding too thin or sharp, and you can always tame the treble by trying out various ear tips.
FiR/Bellos Audio offers quick build times for their custom in-ear monitors. Their estimated build time for the FiR/Bellos X4 IEM is a brisk five days from when they receive your ear impressions, which means you won’t have to wait long to get your hands on the exciting FiR/Bellos Audio X4 IEM.

The 64Audio A6t is a six-driver custom IEM that employs six Balanced Armature drivers to deliver its top-tier sound. The A6t’s drivers are interconnected through 64Audio’s LID - a unique technology that balances out driver impedance for the best sound. You also get swappable
Apex Modules for improved soundstage and in-ear comfort, alongside an ultra-comfortable fit thanks to 3D-Fit.
The A6t offers a well-balanced sound signature perfect for mixing work. With the M15 Apex Module, you get fast, accurate bass with enough power to keep instruments like kick drums from sounding weak and thin.
The midrange is exceptionally clean and balanced, so vocals and instruments sound crystal clear and detailed. The balanced midrange tuning means vocals are positioned in the middle of the mix, and instruments fill the rest of the space around the vocalist.
The treble is outstanding with the A6t. The Tia high-frequency driver makes reaching high-end notes effortless, which results in an airy and spacious sound. Despite the great extension up top, instruments sound accurate without sounding sharp or shrill.
If it's an ultra-balanced high-resolution sound you’re looking for, you can’t go wrong with the 64Audio A6t. Its accurate tone and well-balanced detailed sound make it great for mixing your favorite audio tracks at home or in the studio.

If you’re serious about gaming and want only the best custom IEM for playing your favorite games, you’ll find the FiR Audio Xenon 6 an excellent choice.
FiR Audio Xenon 6 is a six-driver hybrid IEM that comes in either universal or custom build. Both options feature the same driver setup - four Balanced Armature, one dynamic driver, and one electrostatic driver.
The Xe6 features FiR Audio’s ATOM Venting, RIGID, and OPEN ACOUSTICS technology for improved comfort, serviceability, and sound, respectively.
In terms of sound, the FiR Audio Xe6 is a bass-heavy IEM. It does not feature the typical v-shape, u-shape, or even w-shape tuning that bassy IEMs tend to have. Instead, FiR Audio gave the XE6 a unique sound signature meant to give listeners the best sound experience possible.
Starting with the bass, the Xe6 delivers a thick, powerful, and controlled bass. There’s loads of bass quantity in the sub-bass and midbass, but they never bleed into the mids, which results in a clean and well-separated bass presentation.
Mids on the Xe6 get a nice warm tinge as well, courtesy of the generous sub-bass and mid-bass elevation. Vocals sound smooth and natural, while instruments are presented with exceptional detail. You’ll easily hear details like guitar plucks and drumstick impacts with the Xe6.
The Xe6’s treble is impressive as well. The electrostatic driver gives the Xe6 the ability to extend well into the highest frequencies without a hint of strain. High-frequency instruments like cymbals crash with authority and insane detail and sparkle.
The FiR Audio Xenon 6 is an impressive bit of kit for music enjoyment as well as gaming. The Xe6’s bombastic sound will make your gaming sessions more engaging and immersive, and deliver a gaming experience like no other.
Great experience from my first purchase here. Even received a personalized video from the owner for my purchase. Customer service above and beyond in all facets! Thanks so much for a fabulous customer experience!
Amazing customer service. Adam went into great detail with his experience on these IEMs. Would definitely go to him again!
Good communication throughout the process with fast shipping.
It's such a pleasure doing business with Adam and Lauren that I am honestly looking for an excuse to buy more equipment there. I don't really have a good personal audio store anywhere around; and while I am not exactly morally opposed to Amazon or whatever, it's so much nicer dealing with real people and a small business. I cannot even imagine what else I could ask for.
Great work, to communicate every step along the way. Very personal touch. I will visit the office one day to personally thank them. I love the website. I love the product. I love the state where they are located. Awesome awesome awesome!
Everything went really smoothly and I'm enjoying the headset I purchased. It shipped quickly and arrived well packaged. I had a question about my purchase and received a quick response from the seller. I would buy from HiFiSoundGear again.
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...
