IMO it is a waste of money to use studio grade reference headphones for streaming low bitrate music on youtube. I would avoid those specific pairs since they are analytical and detailed, meaning you will hear any flaws in the recording. Youtube is the last place to go to for high quality music. Spotify premium streams at 320kbps where youtube is limited to 128kbs iirc.
The whole topic of bitrate is a beaten horse...it comes down to the genre, how well it was recorded/mastered, as well as perception by your own ears to see if you can tell a difference in fidelity.
There is such a thing as hearing bias and expectation bias. To quote nwavguy
"Just like with taste and vision, our hearing is heavily and involuntarily filtered. Only around 0.001% of what we hear makes it to our conscious awareness. This is hardwired into us for survival. We would go crazy from sensory overload if this filtering didn’t take place 24/7. Studies show you can play the identical track, on identical equipment, two different times, and the odds are good people will hear significant differences if they’re expecting a difference. This is called expectation bias and it’s the brain “helpfully” filtering your hearing to match your expectations—just like wine tasting."
I have found that with my midfi headphones it is possible to tell the difference b/t 128kbps vs 320kbps tracks, but anything higher than that can be very hard to tell at times.

I listened to all the tracks with my Yamaha EPH 100s and after coming back to the site for the third time with no distractions around me I could tell the differences in bitrate. I found some genres are a lot easier to distinguish than others. The third track felt like a mess and I had to relisten to it many times before I could hear a difference. The rest of them it was easy to identify with critical listening, they would sound dull and less detailed. By a slight amount. Lower end headphones also tend to be more forgiving of the track.
TL;DR bitrate is just a number, unless the audio quality is so bad it detracts from your listening pleasure don't worry about it. However the higher the bitrate the higher quality the track will be. If you are using midfi headphones I would try to keep your collection at 320kbps.
Have you already tried the 701 or 702? Compared it to other headphones? Trying them out for yourself is really the best way to go since online descriptions will only get you so far. Neutral headphones can be considered boring, just as headphones with a V shaped sound signature (increased bass and treble with recessed mids) are known as fun. Whether you find them fun or boring is all up to you.
What are your sound preferences, what genres do you primarily listen to?
Will these headphones be used on the go, or at home (is isolation and portability important)?
Will sound leakage be a problem?
What are you comfortable spending for the headphones?
Just a few questions before recommendations can be made.

On another note I did a search for my IEMs on amazon uk and found a pair for 70 pounds. They are fake!
It is easy to tell the difference b/t these two. The top are fakes, bottom is real. However not all fakes are so obvious! Make sure you buy from a trusted seller if you are ready to spend more for higher end headphones.
