This is MTV Evos Festival
45mm beryllium coated driver
32ohm

Like haafee and some others it is a rebrand of quite well received RBH HP-2 headphones

Taken from RBH site "These high-performance beryllium drivers, exclusive to RBH Sound, enable you to experience all the detail of your favorite recordings with true to life soundstage, ambience and fidelity"

Not so exclusive huh? I immediately noticed resemblance to msur drivers.

Msur n350

Msur drivers are bigger, 50mm and sound vastly better.

Not that Evos/RBH is bad. Not at all. What rubs me wrong is that RBH bought some Chinese OEM drivers, choose the cheaper smaller version, charges triple compared to msur (which is wooden headphone) and claim the headphones happened because of their 40 year experience on speakers.

I hate it when speaker companies come around in hopes of making a quick buck. Good thing is atleast I know which brands to avoid when I can go back to speakers.

The side effect of headphones this popular these days, everyone wants to jump on-board and expand portfolio in this direction.

Yeah... I just wish they would bring something new to the table instead of rebranding old stuff. I'm very happy that Focal, kef, Martin Logan etc started making headphones.

Yup, let's be happy with more and more big companies joining the race. Variety is a big plus!

In a recent purchase, a DT880 studio from the eighties I encountered an unusual failure mode, it seems like the magnet got unglued and just stuck on one side of the metal surrounding, pinching the coil on one side.
This mean that the driver still makes sound, but only above 500hz.
Shining a light tough the driver clearly shows it.
not sure what can be done to save tho one, I would have to remove the magnet assembly and re-glue it in place. I guess this might have happened during transport, so the seller might not be responsible...

I happen to have a DT880 driver from the same era at home, but it’s from the ”normal” 880 not the studio, I wander if they were the same unit just with different damping.
The normal 880 driver is completely covered by felt disk while the studio is not covered and the normal has a few of the rear magnet vents covered.
This is the one that I have back home:

Finally, a couple of photos m from the old catalog, if you be not know what I’m talking about.

Alara: first & forth pic is the driver - sorry not taking off the dust cover.

2nd pic is the outer shell (all metal) and 3rd pic inner screen (also all metal)

Not sure if it's only us, but there's this interesting and oddly satisfying vintage quality to these two pics. From some printed mag?

It's from an old catalogue, you can find the rest and many others (not solely from Beyerdynamic) here:
