Some models I can think of that are good headphones for the money and sounds really good.
$50 - superlux hd668b
$100- $120 - ath m40x, ath ad500x/ad700x
$150 - $200 - ath m50x, senheisser hd598, hd558
$200 - $500 - sennheisser hd600, senheisser hd650, ath ad1000x
Can audition m40x and m50x at challenger. Senheisser can audition at connect IT shop at most shopping mall. Ath adxxx series only stereo or jaben can audition.
Think you can go stereo or jaben to audition audio technica and Sennehiser easier so you can settle all in one place depending which location is more convenient for you.
