I have pasted a review I wrote a while back posted on Amazon - saved me saying all the same stuff again.
I've had these headphones for a few months now and so feel in a better position to comment on their merits, in my eyes(or should I say, ears) as they have been burnt in nicely and the headband/earcups have settled in. I have been so enamoured with their sound and comfort, I felt compelled to share this.
First of all, I was looking for some closed back headphones for a degree of sound isolation, as I'm often in an environment where sound needs to be kept in or out. The Focals are exceptionally good in this regard because their memory foam ear cups provide a good seal around my ears. I guess this will vary dependent on the size of your ears, but they work for my "average" size ears. They are obviously not going to be Bose QC25 standard for noise isolation, but they are no where near as "coloured" sounding and muffled as those cans either.
The Focal Spirit Professional cans are the least congested sounding headphones I've ever heard. Now I know that starting with a double-negative doesn't sound like the best way to describe the positive attributes of these headphones, but believe me, when you put these on after some others you will be surprised by the clarity and "see-through" ability of these cans. Now I've not listened to loads of headphones and certainly not headphones in the £500+ category, so I guess you'll have to qualify my comments with cans in higher echelon as I cannot speak from experience. However, given that most people will be spending well under £500, I hope I can make some relevant comparisons.
I didn't purchase my headphones from Amazon, but from Thomann and paid just over £150 for them.
Headphones I have owned or own are:
My main cans before I purchased the Focals were the open backed Sennheiser HD558 - you can get these on Amazon for £120 ish at the time of writing and so this puts them in a similar price bracket. Now when I got the Senns I was blown away by the soundstage, smoothness, comfort and what I thought at the time, clarity. I have always thought that open backed cans gave a better soundstage and up to this point that has definitely been the case, to my ears. Personally, I feel the Focals have an exceptional soundstage for closed cans and what they lack in "air" they make up for in precision. Dynamically, they are light years better than the Senns and tonally neutral and true to life. A lot of headphones I have heard in the past can only be described as harsh. The Senns aren't harsh, which I like, but it's only when you listen to something like the Focals that you realise that headphones tend to be harsh or veiled. The Senn HD558 are definitely veiled in comparison. My Grado SR80's are positively harsh in comparison - dynamic yes, but definitely harsh. On my auditioning journey, I listened to the AKG K550, greatly reduced in price and therefore a definite option given their closed back design. Unfortunately they sounded harsh and congested to my ears and were off my list as a result. Next up I thought I'd try the Shure SRH 1540. Now these are luxuriously comfortable and definitely not harsh in any way. However, they are close to £400 and I thought they had a boosted upper bass and treble, albeit with a nice soundstage and smooth sound - too smooth and slightly lacking in dynamics in my opinion though. I have also listened to the Shure SRH 840(great value, good sound for the money but still a little edgy) and the Shure SRH940(were on offer but I can see why - way too trebly and harsh to my ears with poor bass). Onto the Beyer Dynamic brand, T51i(on ear closed back - I really liked these and nearly bought them. Sweet musical sound and comfortable but I didn't want on ears), DT770(just sounded muffled to me). Audio Technica M50's(harsh and bass emphasis). Sennheiser HD650's as a reference(loved these but they are open backed so there'd be no point buying them given my requirements). There have been others but I forget. So, as you can see, I have tried a few en route. Now I bought the Focals on a bit of a punt, but only after a lot of research and reading of reviews, including those here on Amazon. There are few places to audition the Focal Spirit Professionals in store, so I found the best price at Thomann and bought them, thinking I'd send them back if they were crap!
I've still got them in spite of a few concerns about manufacturing quality(no problems so far) and comfort(some people complained of a high clamping force). They do take a week or so for maximum comfort as they do have a fairly high clamping force to begin with. Mine are fine now, either because I've got used to them or, more likely, they have loosened off somewhat with use.
Finally we get to the sound. Amazing clarity, neutrality, lack of congestion, great soundstage and instrument placement. The treble is smooth and detailed but not overly so. Bass is extended and very detailed but not woolly or bloated in the way "fashion" dictates how bass should be. Dynamics are exemplary - listening to percussive sounds on these is so addictive. They can sound a little dry or bland, I guess, with some recordings because they are none too forgiving of mixing quality or compression, but give them something well produced, they sound amazing. Piano is a great way of testing sound reproduction and nothing I've listened to come close to the reproductive qualities of the Focals when playing back piano sounds. I'm a big fan of Oscar Peterson's playing and his dexterity and touch come through with aplomb.
I have worn these headphones on journeys too and from social events and when people have tried them, on the whole, with the exception of people who don't care, weren't listening or are plain "deaf" to anything of quality, they have been blown away with the clarity of the sound these things produce - as have I.
For the money, they are in a different league from most of the competition around them and provided you are not into the heavily equalised, bass bloated sound of Beats headphones you might be pleasantly surprised. They are a sonic bargain of massive proportions!
Update to review above.
Sonically there is nothing to add, but I am on my 2nd pair because of a crack in the headband which forced me to return them.
New pair are fine for the moment but I don't hold out much hope for these in a year's time, so buyer beware in terms of construction quality.
If they go again I will be looking to another brand, which would be a pity, because these sound perfect to my ears.
Further update (Mar 2017)
My second pair have developed a crack in the headband as well. Sending them back and will be asking for money back this time. Pity because all my earlier comments re sound still apply.
