Focal Spirit Pro for less than $200 is one hell of a deal. I am have not met one person yet that tried them and did not like them. We have to pairs of them and are currently considering getting 2 more at that price.

 

No. Not sure why you would suggest so.

 

For the past 10 years have been enjoying Audio Technica ath m50x exclusively for tracking or for only a quick reference mix. I can't recommend headphones to mix with, but if this was the only option would opt for only the open backed variety as usually at approximately the same price point have better articulation of transients as well as being more comfortable after wearing them for hours. The sound is...well...more open generally and notes to me are more defined and differentiated. My issues with any headphone is that reverb tails tend to disappear in cans and also it is like having speakers unrealistically at the sides of your ears, the soundstage strange and unrealistic. Though, the more you use any monitoring device and discover how they translate to pushing air in a real space, the more proficient your mixes can become.

Sorry, the last experience I have with open backed were the AKG 240's like 20 years ago. I liked using those.

 

Again I said almost not 100 % flat.

 

I think of the Sony MDR7506 as like the Shure SM57/58 when it comes to studio use.
They are a "known quantity" in durability and general acceptance by engineers and performers.
It makes it easier but it is not always the best.
They know they won't break easy and that's important when they are so used/abused.
BUT for a single user, the other stuff being pretty equal, comfort stands out as a factor!
I've used the 7506 since 1994 so if your head and ears are shaped just like mine, you will be happy!

 

I wanted you guys to know that I finally went with Sennheiser HD 280 PRO

After some research, I found that it is one of the best headphones for 100$ range, and It is also closed back, so can be used for music listening in public!

If you look at the range of options in your original poll, it isn't actually possible to vote for these headphones.

I use a twenty year old pair of closed back Sennheisers which cost an arm and a leg and are no longer in production.

What matters most is I know them like an old pair of jeans.
