Focal Lensys Professional

Bought them because needed something to mix/prepare recorded project for mixing and right now don't have room to make properly treated mixing space.
Sound-wise: they do sound close to open back headphones(no excessive mud), shows a lot of "hidden" stuff when checking mix or listening to music(by the way they do accentuate bad cut`s "pops" in tracks so helps to clean up faster), but by the end will need some time to really get used to them.
Isolation is nice (so i can mix anytime and won't wake up anybody), have some concerns regarding recording drums in them but I'm heavy hitter so not that relevant issue.
Build quality seems to be really nice and I'm more than happy that huge chunk of them is made of plastic because otherwise they will weight a lot and put excessive pressure on neck.
Cables and packaging are nice, bag to transport them have hardened shell so I think it can survive few drops and/or putting them in the bag with another sized or heavy stuff.
Summarized: I'm more than happy with the purchase. Thanks Thomann!

The Focal Lensys sound very good, they’re clear and accurate, with a slight emphasis on the mid frequencies, which is a very good thing for mixing. The bass is fast and present but not at all hyped. They’re closed headphones but they don’t have the downfalls that closed headphones usually have, there is no boxiness and narrow sound stage at all.
These are the good things, then comes the matter of comfort.

I was so disappointed to have to send them back that I did a little research. Apparently the average Western male cranial circumference is around 55-57 cm, measured just above the eyebrows and at the prominent bump at the back of the skull. My head is 60 cm, so on the big side but hardly abnormal. I don’t look like a walking pumpkin.
The Lensys’ side bands don’t extend down enough to the bottom of my ears. So I had to push/ stuff my ears inside the pads, which are also very much on the small size. The result is that the top band would pull my tightly packed ears upwards making these headphones a very uncomfortable fit. Had Focal added and extra centimetre or so on each side band, basically an extra click or two, and possibly made the pads an extra centimetre wider they would have been a very good fit.
It seems very strange that with all the R&D that must have gone into designing a pair of closed headphones that perform so well, they decided to make them unsuitable for a part of their potential clients.
I don’t say this in a self centred fashion - looking up “Focal headphones too small” brings up a number of similar cases, all to do with the new small Focal design, apparently the previous series were bigger.
Just for perspective my other headphones are the HEDD HEDDphone TWO, still bought from Thomann, a very old pair of Sennheiser HD600 and some equally old Beyer DT1s, all of which fit amply. As a matter of fact in two decades of professional music making I had never come across a pair of studio headphones which were too small.
So to wrap it up: the Lensys Pro are very good but make sure to measure your head before ordering them.
Thomann’s service was first class as usual, I have asked to be refunded on my account and I will use the money to buy another pair of headphones that have not undergone miniaturization.
