Campfire Audio Solaris 2020 Review







Campfire Audio Solaris 2020 Review



Campfire Audio is a US based company located in Portland – Oregon, which is specialized in the development and production of portable audio equipments such like In-Ear Monitors, cables and headphones.

The Solaris 2020 is the successor of the Solaris In-Ear Monitor that was released in 2019. The Solaris 2020 features Campfire Audio’s T.A.E.C. (Tuned Acoustic Expansion Chamber) acoustic chamber design and offers a Hybrid Driver Configuration with 3 Balanced Armature Drivers (2 for the Highs & 1 for the Midrange) + 1 x 10mm Diameter A.L.D.C. type Dynamic Driver which are implemented in to the Durable Black PVD Finished Metal Body.



I would like to thank Campfire Audio for providing the Solaris 2020 IEM as review sample. I am not affiliated with Campfire Audio or any third person beyond this review and all these words reflect my true, unaltered opinions about the product.




The MSRP price for the Campfire Audio Solaris 2020 is $1.499,00 USD and can be purchased under the link below;




Package and Accessories:

The Campfire Audio Solaris 2020 came in a similar box like the ARA In-Ear Monitor that I have reviewed recently, which shows a unique design that was wrapped with a cardboard that is of USA made “French Paper Company” paper which has a label on the top that features the product illustration along with different type of flowers. The label is surrounded with stars in “Gold” color.

The box itself is made from the same cardboard material with the Campfire Audio logo on the top in Gold color, set in a scene between a sky full of stars and a mountain surrounded by trees that could represent the nature of Oregon where the company is located.

This box is including the following items;


  • 1 pair x Campfire Audio Solaris 2020 Monitors
  • 1 piece x Campfire Audio Super Smoky Litz Cable with MMCX connectors
  • 3 pairs x Foam tips (small, medium, large)
  • 3 pairs x Silicon Ear Tips (small, medium, large)
  • 5 pairs x Final Audio Silicone Ear Tips (extra small, small, medium, large, extra large)
  • 3 pieces x Pouch
  • 1 piece x Cleaning Tool
  • 1 piece x Campfire Audio Pin
  • 1 piece x Campfire Audio Sustainable Cork Earphone Case in Brown Color
  • 1 piece x Warrant Card & instruction manual


Campfire Audio offers a very rich accessories package that includes a wide variety of silicone and foam ear tips.

The Solaris 2020 came with the same protective cork zipper case that has been included in the package of the ARA In-Ear Monitor, but this time in brown color. This Zipper case is a special attraction and an environmentally friendly update.

The sustainably harvested cork surrounds a substantial and protective rubber barrier that ensures that your earphones will remain safe while in transit. The interior is thick faux wool lining that preserves the anodized finish of your earphones. Each case is made in Portugal by a small team of skilled craftspeople that share our commitment to quality.

The Solaris 2020 came also with 3 pairs of double pocket soft pouch’s where you can put the monitors and the ear tips. The cleaning tool and a pin with Campfire Audio Logo are some pretty nice additions.



Features, Design and Build Quality:

The Solaris 2020 has a quite similar shape that we have seen before with the first Solaris In-Ear Monitor, while is now 20% smaller in size compared to its predecessor.


The monitor shell of the Campfire Audio Solaris 2020 is made of a durable black PVD finished metal material that looks & feels very robust in your hands same like with all Campfire Audio products that I have seen before. Each pair of Solaris 2020 is hand assembled in Campfire Audio’s workshop that is located in Portland – Oregon.

The Solaris 2020 features Campfire Audio’s T.A.E.C.™ (Tuned Acoustic Expansion Chamber) technology that offers extended high frequencies response and that reduces the sibilance that could be generated in this area.

On the front of the monitor shell is Campfire Audio brand logo which is engraved in to the faceplate.

At the rear side of monitor shell is the angled sound nozzle which is in silver/metallic color. The sound nozzle is made of stainless-steel material and has a new grill design on the top.

The surface of the rear monitor body reminds me to those of a whale skin texture.

On the top of each monitor shell is the Beryllium Copper MMCX (Micro Miniature Coaxial) connector that looks pretty robust with the mating mechanism.

Each monitor has a vent and a screw in gold color that is located near the MMCX connector.



Campfire Audio Super Smoky Litz Cable:

The Campfire Audio Solaris 2020 came with the so called Super Smoky Litz cable that is made from four large conductors (4 cores) of Silver-plated Copper Litz wire. This cable has a pretty soft, flexible and durable jacket (insulation) in dark grey color with a twisted design.

Super Smoky Litz cable features beryllium copper MMCX (Micro Miniature Coaxial) connectors that provide a robust mating mechanism which is typically made from soft brass. Each connector housing is made of plastic material in smoky grey color and sports left and right indicators.

Both sides of the connectors do come with transparent heat shrink ear guides for extra comfort.

The cable sports a metal Y splitter and chin slider in black color.

The 3.5mm single ended headphone jack has a plastic housing in black color with an L angled profile. The cable is only available with this standard 3.5mm termination, while I would expect a 2.5mm balanced plug that could be used with adapters to use the Solaris 2020 with devices that does support have 4.4mm TRRRS and 2.5mm TRRS balanced outputs.

What I like about the cable is the very low microphonic effect and that it is not prone to mixings.

The Super Smokey Litz cable can also be purchased separately under the link below;





Fit, Comfort and Isolation:

The Solaris 2020 is not the IEM with the smallest monitor size, while the well designed shape of the monitor and reduced size compared to its predecessor makes it pretty comfortable for longer listening periods without to hurt my average sized ear concha’s.

When it comes to the isolation, the performance depends highly to the use of the right ear tips, which are form me the Final E type ear tips which are included to the package. The result is an average performance that is good enough to use the Solaris 2020 in relative noisy environments like the bus, train or metro.



Technical Specifications:
  • Driver Units     : 3 x Balanced Armature (1 x Mids, 2 x Highs + T.A.E.C.) + 1 x Dynamic Driver
  • Freq. Resp.      : 5 Hz – 20 kHz
  • Sensitivity       : 94 dB SPL @ 1 kHz: 6.54 mVrms
  • Impedance      : 15.5 Ohms
  • THD                 : Less than 1%
  • Connector       : Beryllium Copper MMMC (Micro Miniature Coaxial Connector)
  • Plug                 : 3.5mm Single Ended



The Solaris 2020 is a very efficient In-Ear Monitor thanks to its quite low impedance of 15.5 Ohms and a sensitivity of 94 dB. Any source should be able to drive the Solaris 2020 to very loud volumes without the need of any amplification. This makes it also to a very sensitive IEM that catch’s any unwanted background noise which could be produced from your source.

The Sound:

The Campfire Audio Solaris 2020 is a Hybrid In-Ear Monitor with a warmer than neutral tonality that offers a very dynamic sound signature with a powerful but controlled bass response, impressive transparency and detail retrieval in the midrange and a treble presentation that shows a great level of extension and clarity without to sound sharp or shouty.

The Campfire Audio Solaris 2020 is written after a burn-in process of approx. 80 hours. I have used the Final E Type Silicone Tips and Super Smoky Litz cable that came in the box together with the Campfire Audio Solaris 2020.



The low end of the Campfire Audio Solaris 2020 is produced with the special tuned 10 mm diameter Dynamic Driver that offers an impressive subbass performance with a powerful, deep and well extending presentation. The Solaris 2020 shows in general a good amount of intensity without to affect the clarity in this area in a negative way. It offers the listener a nice sense of power that is audible while listen to string instruments such like the contrabass and bass guitar or with percussion instruments like kick drums.

The subbass rumble in tracks such as, Lorde’s “Royals”, Massive Attack’s “Angle” and Armin Van Buuren’s “Vini Vici” was very exiting to hear and to feel.

The midbass region of the Campfire Audio Solaris 2020 shows less intensity compared to the subbass area, while it still pretty strong and impactful in its presentation. It is slightly ahead the subbass region in terms of quantity and extension and is able to add the Solaris 2020 a nice musical tonality. Instruments like cross drums and trumpets are quite accented and do show a warmish and soft tonality. The midbass performance of the Solaris 2020 is stunning while listen to genres like pop and electronic music.

The general performance of the Campfire Audio Solaris 2020 in terms of bass speed and layering decent, while the low end decay is impressive that has yield far better after some burn-in (about 50 – 60 hours).

What I do also really enjoy is the softness and naturalness of the bass notes that are produced by the dynamic driver.



The midrange of the Campfire Audio Solaris 2020 has a slightly warmer than neutral tonality and is able to produce a top level of clarity, airiness and detail retrieval that was shown by the Solaris 2020 in almost any song that I have listen with it.


Vocals & Instruments:

The midrange of the Campfire Audio Solaris 2020 does not shows a typical V shaped character with recessed vocal presentation and sounds fairly intimate and detailed with both male and female vocals. The level of transparency and airiness is on a good level thanks to the well pronounced/highlighted upper midrange and treble area.

The lower midrange has a moderate level of depth and intensity that is sufficient to show a good sense of warmth and fullness while listen to romantic male vocals like Barry White and Isaac Hayes. I enjoyed the Solaris 2020 also with vocals like Sting and Elton John that did sound pretty natural, emotional and have been shown with good level of clarity.

Female vocals on the other hand do sound quite realistic and effortless, while the level of detailed retrieval and realism while hearing the emotions Dionne Warwick, Saskia Bruin and Aretha Franklin or Randy Crawford is simply breathtaking. The general female vocal presentation of the Solaris 2020 is lively.

When it comes to the instrument presentation of the Campfire Audio Solaris 2020, I can say that they do sound in general with a mildly warm tonality and good amount of body. The instrument timbre is neither too analytical nor too dry, while the level of airiness, detail retrieval and clarity in stunning.

Instruments like guitars are slightly bassy, while violins are bright in tonality towards the top end. Other instruments like the piano do show a good level of extension along with a natural touch of brightness. All those instruments are produced in a quite controlled and detailed manner without to show noteworthy negative conditions/situations like over-brightness or sharpness.


Upper Midrange & Treble:

The upper midrange of the Campfire Audio Solaris 2020 shows a fairly natural tonality and is responsible for the nice overall timbre. The upper midrange transitions are controlled and fatigue-free with most tracks and genres I have listen to it.

The upper midrange presentation of the Solaris 2020 is lively, controlled and balanced from instruments like violins and flutes up to female vocals.

The treble presentation of the Solaris 2020 sound energetic and shows a top level of detail retrieval and extension especially in the upper treble region and offers also a nicely tuned treble brightness and sparkle without to be sibilant or sharp.

The lower treble region sounds slightly less pronounced compared to the upper treble area that shows a peak around the 7 – 8 kHz region. The lower treble range of the Solaris 2020 adds to the overall presentation a good level of clarity, while the extension is pretty successful while listen to instruments like snare drums or cymbals and soprano voices like Sonya Yoncheva.

The upper treble region of the Solaris 2020 is able to produce a good level of sparkle for instruments like pianos, hi-hats or female vocals like soprano vocals thanks to a slightly peak in the 7—8 kHz area that is not overdone.

The general treble intensity and quantity is not too much or to low and will satisfy most listeners while listen to a wide variety of genres from pop to jazz, from metal music up to electronic music. The overall control and detail retrieval of the Solaris 2020 is stunning.


Soundstage & Imaging:

The Campfire Audio Solaris 2020 offers an outstanding performance in terms of separation and placement of instruments and vocals. The openness of the stage is the main reason of the spacious sense between instruments and vocals. The soundstage performance of the Solaris 2020 is top of the line in terms of both depth and wideness.



Some Comparisons:


Campfire Audio Solaris 2020 versus Meze Audio Rai Penta:

Both the Campfire Audio Solaris 2020 and the Meze Audio Rai Penta are IEM’s with a hybrid driver configuration that do offer a very esthetic looking monitor housing with top build quality.
