Headphone / Amp for mixing and mastering, Please help !

[modeobsqure]

Hello there

,
i am new in here, hope i am starting this thread in the right place ​

I am a music producer, I've been making Trip-Hop / electronica for a few years now. I am also working abroad (PE teacher), always traveling so i can't have a proper treated home studio.

I am currently using :​

• MONITORS : Presonus Eris E5
• AUDIO INTERFACE : Focusrite 2i4 2nd gen
• HEADPHONES : Audio Technica ATH-M50X
• MSI laptop

I am having a very VERY hard time mixing and mastering songs so I am thinking about buying an openback Headphones. After a long googling session, I felt In love with the Beyerdynamic DT1990 Pro (250uhm) . quiet expensive headphones (600 usd) and yet they need an AMP to run perfectly... (starting from 100 usd)

I know a lot of producers ​

do not advise

to use headphones when mixing but I have not choice.

My questions are : ​

• what do you think about mixing with an openback headphones? please share your experiences
• as I mentioned above, I am using a Focusrite 2i4, do I need to buy a amp to run the dt1990 ? if yes, which price friendly AMP do you guys propose ?
• is there any lower price but yet similar quality headphones you know ?

thank you !

Best
Youssef​
