The Krypton 5 is a revolutionary in-ear monitor designed with the discerning audiophile in mind. Five incredible high-fidelity drivers and innovative technologies like Kinetic Bass and ATOM Venting combine to give you an unparalleled listening experience.
All that sonic goodness is wrapped in machined aluminum shells and mated with Sapphire Glass faceplates for unbeatable looks and durability.
Everything you need is included with the FiR Audio Krypton 5 IEMs!
The Krypton 5 comes with premium features for improved comfort, durability, and aesthetics:
The Krypton 5 comes in both universal and custom build options. Both of which offer wonderful fit and finish and are packed with unique technologies to give you a combination of comfort and durability for years to come.
The KR5 Universal exudes class and elegance with its machined aluminum shells and Sapphire Glass faceplates. The Krypton 5 custom is no slouch in the looks and build quality department either, offering high-quality 3D printed shells you can customize to your liking.
The FiR Audio KR5's five-driver setup is tuned to deliver a smooth, buttery sound perfect for genres like EDM, Pop, and R&B.
The Krypton 5 lets you feel the bass and hear vocals and instruments with next-level clarity and detail. The KR5's expansive soundstage offers plenty of space for every sound to stretch its legs, and the accurate soundscape makes you feel like you're in the music.
The bass on the FiR Audio Krypton 5 is unlike anything you've ever heard in an in-ear monitor.
The KR5's revolutionary Kinetic Bass technology pumps low-end frequencies and vibrations directly to your outer ear. When combined with the Krypton 5's weighty and powerful bass, you'll experience a speaker-like sound where you hear and feel the bass at the same time.
Traditional in-ear monitors seal the ear canal for the best sound performance. The air-tight seal typically leads to discomfort caused by extra air pressure as the miniature speaker drivers move to create sound.
With the ATOM venting system in the KR5, your ear drums can remain relaxed and pressure-free, so you can listen to music for extended periods without fatigue.
Traditional in-ear monitors use sound tubes to carry sound to the ear canal, resulting in a closed-in and stuffy sound. The FiR Audio KR5 does away with these sound tubes, allowing sound from the drivers to flow freely for unrestricted sound reproduction.
The Open Acoustics System consists of three major components: Open Drivers, Sound Reactor, and Sound Reflector.
The Open Drivers allow sound to radiate freely and flow to the specially designed Sound Reactor. Here, sounds are shaped naturally and then allowed to flow freely to a sound reflector, which guides sound waves directly to the ear canal.
The result is a pure, untainted sound for the best high-fidelity sound experience.
From its durable connector to its robust shells, the KR5 is built from the ground up to withstand hours of abuse on stage, in the studio, or at home.
The KR5 universal comes with RIGID tech for enhanced durability. The RIGID 2-Pin and Coaxial Connector are rated for up to 1000 and 5000 connections, respectively, for uninterrupted listening sessions.
RIGID tech doesn't stop at the connectors. The RIGID Snap Screen protects the KR5 from debris while easy to replace when the need arises, while the RIGID 3D Printed Shells in the KR5 Custom are built 20% thicker than competing custom IEMs, for lasting durability.
The Krypton 5 covers frequencies from 20hz and extending to 20kHz - allowing for a wide range of frequencies to be reproduced accurately.
The Krypton 5 is a premium universal hybrid IEM from FiR Audio. Priced at $2,999, the KR5 offers a well-balanced and engaging sound with good comfort and excellent durability.

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.
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...
