Choosing and buying headphones

I have owned a number of Denton and Focal. I would choose Focal of the two. While it certainly depends on taste… I had to buy a big high powered amp to get Denon’s bass under control. Focal are easy to drive, well balanced and detailed… I think a very high quality safe bet to start with. Most of us end up with many pair.

Those 3 are great headphones. I own them and its good. Moreover, consider for other guys opinion too. Have a great day!

Yesterday I listened to hifiman ananda in the store. I liked the sound, but they are huge in size. You can't turn your head too much, they will subside. I also managed to listen to HiFiMAN HE5se, by landing they are much more comfortable than ananda, but the sound is inferior.

Massdrop may not ship these worldwide, but if they do, you should consider these:

The Elex is a modified Elear.  I have not heard the other headphones you mentioned, but I have about a dozen headphones including much more expensive ones like LCD4, LCDXC, HD800, and Sony MDR-Z1R and the Elex more than holds its own.  It is very neutral, dynamic, detailed, and comfortable. 

I had the Sennheiser 650’s for years until I upgraded. They are popular but for me comfortable and sounded good. Not as heavy on the head as some are.
Now they’ve been updated to the HD660S model. Moon Audio carries them, you can inquire with Moon about compatibility with your player. They’re in your price range.
If you can, try them on in person to test for comfort and see if they sound good to you. Take your player.
