Looking For Best Headphones

Hello, I have seen all the threads here I am searching Best headphones I couldn't find yet Could someone can tell me which headphones are best For listening to Music.
This question will bring you lots of subjective answers, so here is mine. There are no "Best" headphones for listening to music! I have listened to Stax headphones since the early 90’s. I currently have the 009’s. I love the electrostatic sound for its quick, clear transparent sound. It truly sounds like a window on the soundstage. I wanted a more intimate sound so I bought a pair of Audeze LCD-XC, and a McIntosh MHA 100 to drive them. The Audeze are incredibly comfortable (albeit heavy) and it would be hard not to like them. The sound is powerful and dynamic but I miss the transparency of the Stax phones, so I move between them.

Could I find a better sound if I spent more money? Maybe. You didn’t mention your budget, but I suspect it’s not unlimited. Jim’s comment above indicates that he loves his Sennheisers, and I’m sure they are great as well. My advice would be to settle on a budget and audition as many as you can. Find a pair that you like, and can live with long term. If you constantly chase different, more expensive headphones it will get expensive. When these lockdowns end, try to attend a Hi-Fi show. They all seem to feature a demonstration room for headphones. Believe me, you will find a pair that you like and an amplifier to drive them. I recommend a tube amp. Good luck in your search.
How much do you want to spend? Arguably, the best bargain reference headphones are the Sennheiser 600 and 650. You can find Senn 6XX on Massdrop for a good savings over the official ones, and they are identical.

The Sennheiser 6XX paired with an Audioquest Dragonly DAC/amp are a sweet combo for listening to Tidal via phone/tablet.

The price goes up from there, especially of you have to add an amp. In no special order (and they have different models)... more expensive ones could include:

I can’t find the headphone review site that used to be my reference... it was absorbed into Absolute Sound’s vortex :(

A suggestion would be to check out some Reviews to gain some insight into impressions, models (differences) and Driver Type.
Darko does many Reviews on Cans, and Headphone Amps / DACs.
A good Amp makes a big difference ... also FYI > IEMs can be very nice
for an exceptional experience.
Listening for yourself if possible is best ( CanJam ).
A DAC with a crossover / blending feature makes a difference as well.
My listening is done with the two types of  Can drivers, Dynamic and Planar both and two amps with one DAC.
The equivalent of two separate systems ...

Best place to learn about headphones is head-fi.com

I think the main thing to figure out is what headphones do not give you fatigue. Then how much to spend to on those non-fatiguing headphones. I hated my prior Senn 600 headphones because of fatigue with my Benchmark DAC3 HGC preamp/DAC.

I now have 2 headphone amps, a $3000 one and a $500 one. For headphone ONLY use the Topping A90 at $500 is highly recommended by me and is very close to the $3K Benchmark HPA4.. It is a neutral sounding amp. It goes great with my $3K Meze Empy, a warmish sounding headphone. I have not heard the $300 Meze 99 Classic but from what I have read on Head-Fi it supposed to be similar in sound to the Empy.

Your choice of amp will also figure in on the fatigue factor. I had a $2K headphone amp that gave me fatigue and it was replaced by the amazing Topping A90 for 1/4 the cost.
Best for what?  Budget?  Sound signtature?  Comfort?  Type of music?  Open back?  Closed back?  No wonder Thor is angry!  No easy answer.
