1clearhead did a write-up on this years ago.
PRO 80 vs. ISK MDH9000
Even though the Pro 80's are probably the best looking headphone out of the bunch it falls short to the extreme sound signature the MDH9000's provide.
BASS: The MDH9000 digs deeper....way deeper! Though the bass on both sounds exactly the same in quality, the bass quantity goes way deeper on the MDH9000, which naturally makes you fall in love with true heard and felt bass for any bass lover.
MIDS: Midrange is better, clearer and livelier with the MDH9000, no doubt about it! The Pro 80 just seems to fall a step behind every time.
TREBLE: Again, the MDH9000 just outperforms the Pro 80's. Details can be heard with great enjoyment without ever feeling that they're going to sound metallic, or artificial to the ear as sometimes the Pro 80's seems to do in certain songs, depending on the genre.
SOUNDSTAGE: Soundstage is just BIGGER and GREATER in every way possible! Because of this, the MDH9000 seems to cover more in overall details from the lowest bass tone to the highest chime in every song.
ISK HP2011 vs. ISK MDH9000
These two headphones have more to offer than any of the other headphones when it comes to quality of SOUND.
BASS: The MDH9000 digs deep, but the HP2011 is very precise for monitoring purposes with quick punch and details. For monitoring, the HP2011 wins, but for DJ use, the MDH9000 wins.
MIDS: There is a sense of realistic vocals and lively presence when it comes to hearing the HP2011, but there's almost as much fun and enjoyment with the MDH9000's signature!
TREBLE: Though both have great treble presence, you can actually pick-up better hi-end details with the HP2011's, where the MDH9000's just might roll-off at certain songs or genres at their very peak.
SOUNDSTAGE: Soundstage is great on both headphones! But, for the purpose served......soundstage for DJ purposes goes to the MDH9000, while soundstage for monitoring purposes goes great with the HP2011.
ISK HD9999 vs. ISK MDH9000
These two headphones have a lot to offer the consumer for their price, and even though their flagship model happens to be the HD9999, the MDH9000 could really be some of the best DJ headphones out there to be had!
BASS: The bass of the HD9999 hits a little deeper with quick response, while the MDH9000 can hit almost as deep, but with more quantity. HD9999 focuses more on sub-bass, while the MDH9000 covers a broader range.
MIDS: To my ears, the HD9999 can be a little bright at times, which for some may make them more enjoyable, or for others, it may not. The MDH9000, in the other hand, sounds more balanced to their overall signature, which for many may be the better answer to longer listening sessions.
TREBLE: Even though the Hd9999 might sound livelier because of their brightness, details are better displayed with the MDH9000’s sounding precise and not splashy as the HD9999 might sound like, at times.
SOUNDSTAGE: Soundstage is similar and is great on both! They are both incredibly fun headphones and many here can appreciate either of them depending on what you’re buying them for. It’s only a matter of preference.

I don't think there are any actual fakes for the ISK brands. Not on Aliexpress anyway. I'm going to buy a new one soon as well. I put it off for now to buy an IEM instead. I think the Anniversary sale just ended, 11.11 should be next later on in the year for good prices. Though I don't think any of the MDH9000's ever went on sale.
