How do I use that with a ps4?

I have ATH-M50s and simply want to be able to game with my friends online.  How could I go about doing this in the cheapest and most efficient way since the headphones do not have a microphone?  Thanks!

Alright, but do you think I would even be able to find music by like Madeon or Lemaitre at the store anyways?

Thank you  for your suggestions, but I simply do not have the extra money to buy all of my music considering I am a high school student and don't have time for a job.  I am from Illinois.  And I also know that there are ways of getting good quality music for free but I just don't know how it's...

So if I don't have cd's that would be your best suggestion?

Alright, thank you for the advice, and I was basically asking what was the BEST source for free music to go along with these headphones bringing them the best quality. I'm sure that's understandable considering everybody who gets nice headphones wants to get the best out of them. And like I said...

I have a laptop.

Basically I am getting sennheiser 598's and I want to get the best quality sound out of them without an amp. and i'm sure that downloading songs from youtube would not be the best way of doing that. where do you get your music from? and what are my options that will still have decent sound...

Sorry, where should I have posted this question?

Hello there, I have just recently decided that I think I would like to buy the sennheiser hd 598's and realized that I have a problem which is that I get all of my music from youtube. I was just curious as to what would be the best way to get good sound quality out of my music for free. I will...

So what headphones would I be able to get that I will not need an amp for? and when I say composing music, I mean it in the most casual of ways. Also, do you know what the comparison between the sony x series and the m50's are?

Well now that I think about it, I will probably use them more while I am at my house and I might even get into a little bit of music composition myself so I still believe I would like to use full sized headphones. Do you have any specific recommendations? And How loud is the noise that comes out...

Thanks! And yes haha. Basically, I was at Best Buy looking around and I was trying on headphones, realizing how amazing they were. Then I decided I would do a quick search online to see what type I should get. Now i'm here....  Anyways, while I was at Best Buy, I tried on the Sony X series...

ok so I don't think I will need an amplifier if i'm thinking correctly because I will be using these headphones while I am walking around.  I really don't know much about music quality so i'm not too sure what type of sound i'm looking for in headphones, but would the best headphones for techno...

Would you care to explain what soundstage is? And the only thing about the K702 is they are ugly. I would not be able to get myself to walk around wearing those.  But thank you for your input! I will definitely consider it when making my decision.
