Operating Principle: Open-Back

Impedance: 55 Ohms

Loudspeaker: 40mm 'M'-shaped all-Magnesium driver.

Following in the footsteps of the Focal Clear open-back headphone, the re-tuned Clear Mg features fine chestnut leather and microfiber materials on the headband and ear pads with a cool honeycomb pattern that decorates the earcups — and of course, as the name suggests, Focal’s special 40mm 'M'-shaped all Magnesium full-range driver. Needless to say, we were pleased to receive the Clear Mg to write our review for the refreshed open-back headphone classic from Focal.

The original Focal Clear was one of our top-selling headphones and became our go-to for an open-back design. In case you aren’t familiar with open-back headphones and their distinct advantages, open-back designs can be identified by their open drivers (typically with mesh behind the driver), which gives the sound a more spacious feeling and a wider soundstage

The Focal Clear Mg Open-back Headphone does a fantastic job of creating a defined soundstage without sacrificing low-end. The bass remains tight and very defined without being too forward.

The impedance on the Focal Clear Mg is 55 Ohms, meaning they can be powered using a portable audio device or laptop. However, it is highly recommended to use a headphone amp to hear their full potential.

Used in many Focal headphones, the Clear Mg utilizes an M-shaped inverted dome loudspeaker to produce full and accurate sound. The original Clear featured a 40mm driver made from a combination of magnesium and aluminum and a copper voice coil. However, the Focal Clear Mg has been re-tuned with a new speaker driver cone material. After four years of research and development, Focal developed a dome with an all Magnesium cone for the Clear Mg full-range driver.

The new alloy allows the speaker driver to be even lighter, and more rigid than the original aluminum-magnesium driver. This gives the Clear Mg the ability to produce frequencies (5Hz-28kHz) that go below and above human hearing (20Hz-20kHz).

When testing the new Focal Clear Mg, we immediately noticed how comfortable they are! The earpads and headband feature perforated microfiber memory foam, designed to fit firmly while remaining breathable and soft. Not only are they extremely comfortable, but the 1-millimeter micro-perforations help give an impression of open space and extended soundstage. Like all of the headphones in this comparison, the ear cups have the standard vertical pivot, while the yoke allows them to rotate laterally for a proper fit to any head shape.

The sound of the Clear Mg makes them worth every penny. Since the original Clear already reproduced a pure, effortless, realistic sound, just think of even more impactful music, revealing even more — more precise micro details, more realism, and more accurate dynamics hiding in the headphone’s wide-open soundstage. They are incredibly balanced, meaning no level (bass, treble, mid) is exaggerated or dull.

To test the Focal Clear Mg, we first connected to the Chord Mojo 2, and then followed with the Mark Levinson No. 519 to demonstrate a popular setup compared to a luxury setup. On both, we played a mix of Jazz, Acoustic, Rock, and Electronic. The standout genre to our ear was Jazz — these headphones can reproduce the amazing sound stages in the recordings, along with minor details. Although, they sound fantastic with just about any genre we played. If you have an ear for detail, the Clear Mg is for you.

Focal Utopia 2020

Operating Principle: Open-Back

Impedance: 80 Ohms

Loudspeaker: 40mm 'M'-shaped Pure-Beryllium driver.

Continuing on the path of open-back headphones, the Utopia 2020 Kit is the Clear Mg's big brother and Focal’s flagship open-back headphones, adding new technology to 35 years of innovation to make them one of the best on the market. While these headphones aren’t for those on a budget, they use the ideas from their already great-sounding Clear Mg and take it to a new level! Plus, as a bonus, the new Utopia 2020 kit is now bundling some high-end accessories — including a leather owners' manual wallet, updated cables, and a lightweight rigid carrying case that’s similar to the other headphone cases in the lineup.

At an impedance of 80 Ohms, the Utopia 2020 requires a headphone amp to get to a listening volume that shows their jaw-dropping dynamics. The reason the headphones are so tough to drive is a combination of the monolayer voice coil, magnets, and their Beryllium “M” shape dome. The results show for a headphone that can drop down to 5Hz and reach as high as 50kHz, far beyond our range of hearing and even higher than what some studio mics can capture. This allows for high registering frequencies to be played, and while you may not be able to audibly detect them, they add texture to instruments like pianos, harps, cymbals, and brass instruments.

Besides just the technical advancements in Utopia 2020, they put forth some extra effort to make these headphones some of the most comfortable. After all, what are great-sounding headphones if you can’t stand to wear them for more than 30 minutes? The Utopia only weighs about a pound and features perforated, ultra-soft lambskin leather on both the padded ear cups and headband for extended comfort and breathability. Additionally, the Utopia uses carbon fiber in the yoke to offset the weight of the dedicated motor structures.

The sound from these headphones will blow you away. All of these headphones do an astonishing job of recreating music with amazing detail, but Utopia 2020 delivers an experience that most people haven’t heard.  To many, sounds unbelievable for a headphone, but most who hear the Utopia will agree that they are like no other.

Testing the Focal Utopia 2020, we used the same power sources as the previous test: the Chord Mojo 2 and the Mark Levinson No. 519. We also connected this one to the Naim V1 DAC/headphone amp in our Uptopia 2020 review. While all of these powered the headphones well, allowing them to show great detail and dynamics, the Utopia’s full potential could be heard once connected to the Mark Levinson No. 519 and the Naim V1. The combination of these two placed us in the song, hearing details that we had not experienced before.

With the open-back design, the sound was given a spacious room-filling illusion. One of the surprising songs that stands out to us is Punch Brother’s title track “All Ashore.” At the start of the song, a banjo starts lightly playing and is accompanied by a mandolin. On the mandolin strings, you can hear the details of the pick lightly scraping and popping as it comes off. When tested with other headphones, you could hear the sound, but without the same amount of detail. If you are looking for hyper-realistic, immersive sound, and looking at high-end, open-back headphones, you have our approval to splurge the extra money on the Utopia 2020.

Focal Celestee

Operating Principle: Closed-Back

Impedance: 35 Ohms

Loudspeaker: 40mm 'M'-shaped Aluminum/Magnesium driver.

Moving to a closed-back design, Focal’s Celestee headphone is another re-tuned design inspired by Focal’s very first full-sized closed-back headphone. The goal was to create a headphone that was isolating, but still retained the sound quality of past models, even borrowing elements from both their structure and materials.

The Focal Celestee was designed with mobility in mind. With an impedance of 35 Ohms, they can be powered by a laptop or smartphone. The closed-back design ensures isolation from outside sound wherever you are.

Although an important benefit, portability wasn’t the most important design element in creating these headphones. To make the Celestee what Focal refers to as a "re-tuned design" on their first audiophile circum-aural closed-back headphone, the Elegia, the sound of the Celestee had to not only meet Focal's standards, it had to improve on its predecessor. Based somewhat on the Focal Elegia regarding the driver and dome materials, Celestee has been further refined and re-tuned with more emphasis on the lower-end frequencies — a popular request by many Elegia owners. Focal added their special 40mm 'M'-shaped Aluminium/Magnesium driver, which is a similar loudspeaker to the Focal Clear Mg.

This driver material is not as premium as the pure-Beryllium or even the all-Magnesium drivers Focal is famous for in its most luxurious headphones for home use — however, if you are wanting the Focal sound-profile for use on the go, or even at home, we think Celestee is a fantastic choice for less than $1,000. The Celestee keeps the astounding detail that the others have, but without the same design and driver combination as the others in the lineup, they don’t possess quite the same soundstage. With that being said, the design allows the Celestee to be much warmer and deliver articulated low-ends.

The construction of the Celestee is reminiscent of the Clear, in that they have the same yoke and shape, but the microfiber material on the earpads is navy blue. In terms of looks, Celestee features navy blue finishes on the earpads, headband, yoke, and ear pads with soft copper details decorating the speaker driver grills, cable connectors, and rings. Overall, they keep the same cushioned comfort as others in the lineup and weigh just under a pound, so you won’t feel the fatigue of heavier high-end headphones.

We tested these headphones with four different power sources: the two from the other tests (Chord Mojo 2 and Mark Levinson No. 519) but added an AudioQuest Dragonfly and a laptop as reference. We tested these using a few songs from various genres: Elliot Smith’s “Between the Bars,” Jackson Brown’s 1977 live version of “Shakey Town” from Running on Empty, Chet Baker’s 1954 recording of “My Funny Valentine,” and various synth and electronic-based songs.  The results incrementally step up as we go through the sources.

With the laptop, high-ends were chopped off and the bass was weak, decidedly not able to deliver the full Focal sound that you come to expect. After moving to the AQ Dragonfly, those tones start to reveal, displaying crisp and detailed trebles and accurate bass. As you move to the Mojo 2, the headphones start to really shine, delivering punch and crisp vocals that make the acoustic songs sound close and personal. Taking the leap to the Mark Levinson No. 519 polished the sound, but it wasn’t the jump that we heard from the others in the lineup – that may be due to their lower impedance or qualities associated with their driver.

Overall, the Focal Celestee has an amazingly wide soundstage that is hard to find in other closed-back headphones, crisp detail, and tight, accurate bass. If you’re a person who loves heavy low-ends, these might not be the headphones for you, but if you want warmth, then they’ll be perfect.

Focal Stellia

Operating Principle: Closed-Back

Impedance: 35 Ohms

Loudspeaker: 40mm 'M'-shaped Pure-Beryllium driver.

For our last headphone, we have Focal’s brand new flagship closed-back design, the Focal Stellia. This headphone is one of the most impressive headphones that we have tried, and not just for a closed-back. Focal made these with some of the same portable ideologies as the Celestee, but went all out with the sound, making these absolutely remarkable. While they are set at a high price point ($3,000), they’re worth every bit if you are a headphone enthusiast. The Focal Stellia shares the same dome material and shape (1.6"/40mm pure Beryllium "M" shape dome) as the $4,000 Focal Utopia 2020, but with the impedance of the Celestee. The frameless voice coil and closed-back design make the Stellia the perfect headphone for on-the-go or at-home listening.

Focal Headphones Stellia

The design and construction follow the same path as the other Focal lineup but add cognac and mocha finish with full-grain leather cushions and headband. These are just as comfortable as the Utopia 2020, and the overall design and color make these an immediate eye-catcher. These headphones make you want to sit and listen to a full album after playing one song.

We didn’t know what to expect out of a closed-back headphone with a Beryllium dome. After letting these break in for around 50 hours, we started our testing with the Chord Mojo 2 and were immediately blown away! We played Pink Floyd’s “Time” and that’s when we realized these were something special. The ticking clocks and deep drums became three-dimensional and every detail revealed itself. At the 2:20 mark, David Gilmour’s voice floats in front of you. The low-ends in the Stellia are strong and tight without being overpowering, similar to a high-quality floor standing speaker, while the highs are crisp and defined without being remotely piercing.

To test soundstage, we moved up to the Mark Levinson and played Yosi Horikawa’s “Bubbles.” The song starts with what sounds like ping pong balls, marbles, and kickballs bouncing on concrete towards you. With high-quality headphones, you get a sense of room space and can almost point to where each bounce is. With the isolation and detail of these headphones, they make you feel like you’re a part of the show. If you are searching for the perfect pair of closed-back headphones, the Focal Stellia is your answer.


Each of these headphones have their own price point and defining qualities to fit your ear and lifestyle. Focal’s entire lineup is the result of 40 years of innovation and craftsmanship and any headphone of theirs will be an impressive addition to your setup. If you’ve been looking for a high-quality, comfortable, and great sounding headphone, strongly consider Focal.
