  Out of any open-backs I've heard, only the planars manage to have bass that sounds like a good closed back-- ie bass that extends down really low with authority.  Even bassy open-backs like DT990 tend to roll off in the sub-bass.

so is there is a good planar headphone that is below 700 USD that gives me the sound I want

+1

HE500 +2.
 
I posted in the deals forum that you can get a new HE500 for $549 (Hifimans rarely go on sale, MSRP $699) from Razor Dog Audio right now... see the thread or PM me if you want details

I am starting to think of buying the v mode m100, am I moving in the wrong direction

 

[davidsh]

Think it will be good if you are to use them as portables and utilize that they are closed headphones.
 
Oth, HE-500 for 549$ is a steal

 

[elmoe]

DT990 Pro 250ohms for 145usd on amazon right now, might want to try that instead of the much more expensive HE-500 to start with.

 

[Sound Eq]

final question although I am open to pay up to 800 USD 
 
I would like to ask how do you compare dt990 to HE500, is there a big difference between them

 

[davidsh]

Yes I suppose the difference is very big.

If you think the m50's has too much mids and treble, then the hifiman planar magnetics might not be for you.

A much better option is to buy a used lcd2. It has quite the smooth sound signature.

The Philips x1 is also a good choice.

That's what I said but people kept recommending headphones with elevated treble like the DT990.

Before you buy the DT990 or HE500 here's a graph of them compared to your M50.  If the mids and highs are the issues you're having with the M50 than neither of these headphones is a solution. 
The Philips Fidelio X1 is the headphone you should be looking at.

I disagree. I have both and the HE-500 is my perfect headphone. The M50's? Not so much. Plus it has a lot of siblilance for me.

That's fine, that's your opinion. I know people love to recommend their favorite headphones but the problem is he don't have your ears, people hear things differently, I've seen people say the same thing about the DT990, some people even say the K701 has lots of bass, that's why I used the chart, it's an unbiased source. I know these charts don't show everything and they should not be the sole reason to buy a headphone but it does give you a basic idea of what you might be getting and should be part of your research. 

 

[TMRaven]

The charts definitely don't show everything.  M50 has miles more sub-bass compared to the DT990 as one example.

 

[kraken2109]

If you think M50s aren't bassy enough and don't like mids and treble, I'd say you're a basshead
There's nothing wrong with that.
