Best Campfire Audio Mammoth Detailed Review!

  • by

Campfire Audio has once again introduced a new IEM. This time, we will evaluate the brand-new Campfire Audio Mammoth. An audiophile earphone with a hybrid driver architecture (2BA + 1DD) and a mid-range pricing. They have been in my possession for around six months, and I believe that a large number of people will be interested in them due to their attractive price point and distinctive design. This earphone stands out because its appearance and sound are so distinctive. The Mammoth is massive in terms of sound, aggression, and bass, as this review will demonstrate. If you are a bassist, you should continue reading.

The Mammoth, like all Campfire Audio IEMs, have class-leading build quality.

Campfire Audio produces some of the world’s finest headphones. Fans appreciate them for their exquisite beauty and impeccable construction. In my opinion, this is the company’s most aesthetically pleasing earphone to date. The logo’s blue tone with shimmering black paint accents strikes a wonderful balance between formality and playfulness.

The design is time-tested and has been Campfire Audio’s signature for years. Many have come to appreciate their angular, almost industrial look distinctive design. This housing is present on numerous Campfire Audio IEMs that I own, and I can vouch to its durability over time. The metal body inspires trust that the product is of superior quality and engineered to withstand harm. There is no need to coddle and pamper the Mammoth; use them anyway you choose and they will continue to function.

As usual, I am not the biggest fan of Campfire Audio, but given how nice the Mammoth is, it might be wise to invest in a Euphrosyne cable with blue accents to complement the IEM. Or, if you want a truly premium experience and use various source components with different balanced outputs, I recommend the Monarch MKII cable, my favorite luxury cable upgrade at the moment… And it won’t bankrupt you like a Dunu Hulk might.

In any case, I believe the best approach to demonstrate the construction and design is to show you photographs of the Campfire Audio Mammoth alongside comparisons to other popular IEMs released in 2018.

The Mammoth is not a typical IEM. They make no pretense of attempting to produce studio balance and sound. They do not stick to the standard flat tuning since they have no shame. What they do possess is a bass that is thundering, teeth-rattling, and head-banging. This is an audiophile earphone for bass heads, and it is, to say the least, an experience to listen to them with the proper experience.

The Mammoth personifies why I am such a devoted fan of Campfire Audio. Instead of adjusting earphones to match the curves of snooty and uninteresting reviewers and their graphs, they tune earphones for the individual who will be using them. Focusing on the frequencies and presentation that make that genre the most enticing and tuning them to the genre that the individual will primarily listen to. They have the Holocene for critical listeners, the Andromeda for versatility, the Solaris 2020 for natural and magnificent presentations, and the Dorado for smooth and warm lovers.

They already possess a basshead earphone, the formidable Vega 2020. Its white, dazzling, innocent appearance is in no way indicative of the nasty, dirty bass lurking within. But that IEM costs over $1000; why not create a bass head earphone at half the price, making it more accessible to the general public? This is the Mammoth; it has the proper DNA and works exceptionally well. Let’s investigate the sound in more depth.

The Mammoth is a V-shaped earphone that packs a punch and keeps the beats flowing. I enjoyed listening to this alongside my EDM collections. Listening to industrial electro and psy-trance, which I was so into many years ago, was really entertaining. It brought that music to life by hitting strongly in the soaring high spots and then crashing with a ghostly growl in the sub-bass passages.

  • The Low End

The bass is our starting point. It is by far the most prominent feature of the earphones, and when paired with the proper music, it is fantastic. Used with more tranquil genres that demand less elevation in this frequency band, I’d consider it excessive. It can function as an all-purpose earphone, although it is not ideal.

Back to what it does well, which is producing sub-bass. The lowest of lows rumble and echo and attempt to replicate the enormous presence of a large speaker assaulting the eardrums. It never loses its poise or gets unruly even when the bass dips to its darkest depths.

Mid-bass is also handled quite well, with a great deal of texture and clarity. I’m assuming a high-quality driver was used because this type of reaction requires a certain degree of tightness to appropriately portray this region without flowing into the midrange. The double bass and other strings in the lower octaves sound exceptionally well in terms of both weight and precision.

  • Midrange

Similar to previous Campfire Audio products, the midrange has a tiny roll and a great deal of smoothness. Detail is provided by the balanced armature drivers, but they have been tuned to be less forceful in order to avoid fatigue. Male vocals sound buttery smooth and substantial, and female vocals benefit from the middle tuning curve rising upwards towards the treble at the optimal spot.

Detail retrieval, imaging, and spacing were all excellent in this region. This demonstrates the advantage of hybrid drivers in their ability to perfectly reproduce the best components of each frequency.

  • Treble

The treble does an excellent job of giving the appropriate amount of vigor to offset the deep low end. It is what keeps the headphones entertaining and exciting. When you reach those rising highs just prior to a bass drop, you should feel the music building. The anticipated release of the insanity is imminent. This accomplishes the desired effect without being harsh or sibilant.

It’s almost as though the treble tuning was taken from the more costly Andromeda headphones. The forward positioning contributes to the appearance of an expansive and spacious soundstage, which is characterized by a high level of detail and clarity.

  • Contextually

When discussing the sound of an earphone like the Campfire Audio Mammoth, I believe it is essential to provide context. Are these headphones for purists? No, this is not a versatile headphone that sounds fantastic with all genres. Again no. It is capable of performing well with a variety of genres, but is intended to satisfy bassheads. As a former employee of industrial electro clubs and psytrance events, I find the tuning to be impeccable.

I make no apologies for approaching this review from the perspective of a basshead. If you are searching for a more rounded and balanced experience, there are a number of possibilities on our list of the best audiophile earphones or in the section on IEM reviews.

Currently, there are three earbuds that I consider to be the gold standard for bass at their respective pricing points. The Mammoth follows The Mangird Xenns Up and The Campfire Audio Vega 2020. It fits perfectly into that category.


This review has been in the works for quite some time. I’ve owned the Campfire Audio Mammoth for six months, and I use them frequently. I listen to a great deal of classical music and jazz, for which these headphones are not appropriate. However, when it’s time to bang, the Mammoth or the Xenns Up is my weapon of choice, and if I had to choose based on appearance, build quality, and wow factor, it would have to be the Mammoth. With a solid aftermarket cable and perhaps some Sendafit ear tips, you’ll have one of the baddest basshead IEMs in the world.
