Campfire Audio Holocene & Mammoth Earphones Unveiled

The Campfire Audio Holocene and Mammoth audiophile-grade earphones are finally here and we suspect they’re really, really good.

Campfire Mammoth Earphones with Cable

Apple Music’s launch of its lossless tier didn’t exactly go off without a hitch but the Spatial Audio component (not a lot of music exists yet that really shows it off but more is coming) does benefit from better quality earphones. Recognizing the need for audiophile-grade sound and quality in a unique, eye-catching package, the Campfire Audio Holocene and Mammoth earphone designs will connect listeners with their favorite artists better than ever before.

Campfire Audio have been quite busy this summer with multiple new product introductions and we’re excited to see that they are focusing on more affordable IEMs with these two new products. Not everyone can afford to spend over $1,000 for audiophile-grade earphones so when you introduce 4 new really high-quality earbuds in one month below $650 USD — that’s a very good thing for consumers.

The brand new Campfire Audio Holocene and Mammoth earphones are not inexpensive but they appear to offer a genuine audiophile-grade experience far below what other brands are charging for comparable IEMs. 

The Campfire Audio Holocene [$649 USD] and Mammoth [$549 USD] build off Campfire’s legacy of elegant, handcrafted earphones and in-ear monitors by utilizing Campfire’s signature 3D printed acoustic chambers and precision matched drivers to deliver a peerless listening experience in two distinct sonic flavors.

The Holocene’s sound profile offers an even, balanced frequency response across its entire range, giving listeners exceptional clarity and a high-fidelity representation of their favorite artist’s sonic vision. Mammoth is bold and vibrant, ideally designed to deliver an enhanced listening experience to the person who likes to turn things up and feel the bass, mid, and treble in all the right places.

Glow in the Dark?

Ensuring Campfire’s commitment to crafting products that are both robust and refined, each model is machined from aluminum, connected with black tri-lobe screws, finished with a black PVD stainless steel spout, and completed with the company’s custom beryllium MMCX connectors ensuring years of stable performance.

Campfire has also given Holocene and Mammoth a unique and striking visual appeal, with integrated glow-in-the-dark elements on the earphones and cable overmolds, giving them a dynamic look after dark.  The units also ship with a custom-designed zipper case made of SEAQUAL® upcycled marine plastic with glow-in-the-dark features and unique patterns on every case.

For some that might seem like a cheesy gimmick, but for those of us who run at 4 a.m. and hate looking for their earphones or case in the dark (my wife enjoys her sleep), this will prove to be a great feature.

“When we designed Holocene and Mammoth, we soon discovered each had its unique voice, and both had something special to offer the discerning listener.” said Caleb Rosenau, Vice President of Campfire Audio.

Holocene gives you all the nuance and detail out of the most layered recordings without intruding on what the artists intended for us to hear.  Its clarity and resolution shine a bright light on your favorite recordings, so you hear more than you ever have before.  Mammoth is exciting, visceral, and simply an enjoyable sonic signature.

You may find yourself turning up the favorite parts of your favorite songs with Mammoth because I certainly did.  Both are going to give you an amazing way to listen and connect with your favorite music in an honest and intimate way.  These are exceptional products, and we’re excited to get these into people’s hands so that they can enjoy them as much as we do.”
