Hi, 
 
I am currently looking for over-ear (preferably) headphones. I do not want to pay more than 300 bucks. 
 
I am planning to buy an amp if it is required (Will Fiio E10 be enough?) 
 
I am looking for open headphones
 
I would like to also note that I have the ATH-m50s and they sound great but I want something more. 
 
Examples of bands I listen to: 
 
The Smiths
The Beatles
The Stone Roses
Arctic Monkeys 
 
(basically pop/rock)
 
Although I would appreciate it if the headphones would also be wide-ranged enough that I can listen to some classical every now and then. 
 
I have heard that Grados are good for rock in general but they are on-ear, am I right? If the sound is THAT much of an improvement in the categories of music I listen to then I would be willing to compromise but over-ears are preferred. 
 
Thank you for any input, I really appreciate it! 

Hi,

You should consider Philips Fidelio X1.

Grados under 300 are on ear, with pretty small soundstage and are also bright sounding headphones (not everyone like them). They could be your cup of tea but it is wise to try them before buying.

Best Luck!

I will certainly try the Philips out at my local store. 
 
Is the sound similar to what Grados produce? 

No, Fidelios are warm, smooth and extends well into the lower octaves. Their highs are soft and their sound signature is pretty forgiving and never agressive. They don't sound as 'in your face' as Grados.
 
On the other hand, Grados have bright (some would call agressive) highs in comparison, they have more forward presentation and sub bass is maybe lacking in comparison.
 
It's a matter of tastes.

Thank you! I shall try both of them out and decide what I like best. 
 
Anymore suggestions (<300 and good for the type of music I listed)? 
 
Your input is appreciated 

Most important (I forgot to mention) is that I do not like muddy sounds at all. 
 
I'm looking for a clear set of headphones with a defined bass(tight).
