What are reference headphones for?

Reference headphones are designed to deliver sound as accurately and neutrally as possible, making them ideal for critical listening, mixing, mastering, and audio production.

Unlike consumer headphones that often boost bass or treble for a more exciting sound, reference headphones aim for a flat frequency response so you can hear every detail in the mix without coloration. This lets audio engineers and musicians make precise decisions about levels, EQ, and effects, so listeners can enjoy a smooth and accurate reproduction of sounds. Whether you're in a studio or working from home, reference headphones are essential tools for professional-grade audio work.

Dan Clark Audio Stealth Headphone

Price: $3,999.99

Crystal-clear, life-like sound for precise sound monitoring and mixing

The Dan Clark Audio Stealth is a no-compromise flagship built for those who want reference-grade precision in a closed-back form. Engineered to vanish on your ears and sink you deep into the music, the Stealth lets you hear exactly what the artist intended without distraction.

Powering the DCA Stealth is a fourth-generation planar magnetic driver paired with AMTS (Acoustic Metamaterial Tuning System), a unique tech that controls high-frequency distortion and eliminates treble sharpness. Together, these technologies give you incredibly low distortion, razor-sharp detail, and a smoother, more natural treble that's never fatiguing - even during long listening sessions.

Tuning-wise, the Stealth leans neutral with a subtle touch of warmth. You get tight, well-extended bass without bloat, mids that keep vocals and instruments lifelike and centered, and a treble that’s crisp without being fatiguing. The wide, three-dimensional soundstage and accurate imaging give you a realistic sense of space, making it easy to pick apart layers in a mix or enjoy immersive playback.

Comfort is top-tier thanks to a self-adjusting headband that conforms effortlessly to your head. Meanwhile, a lightweight chassis reduces fatigue, and plush suede leather earpads ensure you can stay comfortable even in long studio sessions. The foldable design and included travel case make the Stealth a surprisingly portable flagship-level headphone, while the matte black finish and carbon fiber accents give the Stealth a sleek, understated but undeniably premium look.

If you want true, reference-level performance but don't want any of the downsides of open backs, the Stealth delivers. With its studio-grade accuracy, premium comfort, and real-world versatility, the Stealth is a serious tool for pros and audiophiles alike.

The Dan Clark Audio Expanse is a flagship open back that takes reference listening to the next level—transparent, uncolored, and deeply revealing. Designed for critical listeners, engineers, and audiophiles who demand truth from their gear, the Expanse doesn’t embellish or hype - it simply tells it like it is.

At its core is Dan Clark’s fourth generation planar magnetic driver, paired with the proprietary AMTS (Acoustic Metamaterial Tuning System).

What you hear is exactly what’s in the mix, nothing more, nothing less.

My new favorite audio store - everything I missed in a local store

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!

Unexpected surprise!!

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 :)

Don't believe everything you "hear"

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.

Best service

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.

Excellent Service!

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!

Absolutely breathtaking customer service!

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!

Incredible Product And Service

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.
