Which is the better studio headphone when it comes to sound quality, Sennheiser 280 or Sony MDR-7506?

From looking at the attached screenshot, does anyone think the headphone the radio personality is wearing is the Sony MDR-V600?

GREQ, Thanks for identifying the headphones in the video. I have been looking at pictures of both the MDR-V600, and the MDR-v900HD and agree that its most likely the V600. Have you had any experience with the 7509HD? If so, is the sound quality better than the 7506?

GREQ, Yes, the other guy in the video is wearing the Sennheiser HD65. However, that isn't the headphone I'm wondering about... I found a better Facebook video https://www.facebook.com/95kqds/videos/10154442437889121/ The guy with the gray zip up sweater. Definitely are Sony cans, but the...

Here is the Facebook video for these mystery headphones. https://www.facebook.com/95kqds/videos/10155574130994121/ It's the first guy when the video begins with the Sony headphones. I'm hoping that someone will be able to identify the model, but it may be hard to tell.

GREQ, These mystery Sony headphones are full size over the ear, and I believe the earcups were round and not circum like the 7506. Both earcups had Sony branding on each side and a gold strip on the bottom I'm starting to go crazy not being able to find the model...

Can anyone think of an older full size over ear black Sony headphone with white and gold colors on the earpieces? The unit looked like it might have been a Pro model, but I'm not sure as it did not resemble any of the 7500 series After doing a few Google image searches, I didn't see any cans...

Has anyone experienced a headphone jack in a portable device going bad from using a headphone with a coiled cable?

What does everyone think of the Sennheiser HD 200 PRO? I've been using them off and on for a few weeks now, for music listening, They are indeed bright sounding as I've commonly heard in studio monitoring headphones. Bass is decent, but true to the orignal recording as a studio headphone...

Too bad the Beats Studio 3.0 wasn't a professional grade headphone, or I might consider buying it. Already had the corded version of the Studio 2.0 a few years back, Build quality wasn't so good, earpiece hinges broke 2 times over on each side and the input jack on the headphones failed...

Recently, I purchased the new model 280 PRO. However, the noise isolation doesn't seem to be as good as the original model that my buddy has. Does anybody else feel the same way?

The cushion on my 598 came unstitched from the headband 2 times over. Sennheiser sent me a brand new pair of 599's as my 598 was still in warranty. And yes, the 599 headband cushion does seem higher quality!

Is it just me, or does the Sennheiser 280 PRO 2nd Gen have less noise isolation than the original? Because I recently purchased the 2nd gen and it does a fair job of isolation, however, I can still hear people talking when I'm in public, and I can hear the engine running when I'm on the bus...

Do the Fiio MP3 players have their own software to manage content?
