ATH-M40x

I have the ATH M40x which are a lot better for bass heavy material and mixing then the M50 (check Oratory1990 here on reddit for analysis and eq), and the DT990, both are good but it is really tricky to properly mix on headphones at all. I'd go DT990, oratory1990 eq and cross check on as many speakers as possible. You'll be good.

I prefer the ATH-M40X as the 50's have too much bass.

Hi there. Efnote recommend the Audio Technical M50x or M40x. I own the former and it’s amazing. I managed to find mine second hand for about a hundred bucks Australia on Marketplace and have since bought multiple pairs new for other edrum projects. The M40x is a bit cheaper and you can sometimes find it new on sale.

If you opt for Audio Technica instead of AKG, I'd opt for an M40X instead of the M50X. Audio Technica went a bit overboard with the Low End on the ATH M50X, so they sound colored.

I also edit on a Mac mini and I use a pair of Audio-Technica ATH-M40x headphones. For critical listening you need a good pair of over-the-ear studio reference monitor phones for accuracy, comfort and passive isolation. What you don't need is active noise cancellation specially in consumer grade headphones that will add lots of bass. The M40x that I use have a more neutral response which is what you need for editing, especially voice. Do not get earbuds. Do not get consumer grade or cheap quality headphones if you want to do critical work. Invest in good headphones. Audio is important, much more than good color correction or visual effects.

Look, I know that you're trying to get an all-purpose headphone set that functions as your work pair as well as your casual listening pair. The thing is that you seriously need to consider buying two pairs; one wired pair for critical editing work, and another set of earbuds with ANC for casual listening. Reference studio monitoring headphones aren't optimised for casual listening - they're too flat, they are optimised for accuracy and editing work such as balancing voice and background music, etc. What you need are two separate sets of listening devices.
