Audiophile: I want my system to replicate a live performance
Also Audiophile: I listen at 60dB.
Seriously though, I think your phone is not accurate. 60dB is really quiet - for example an acoustic guitar 10ft away is louder than that.
I love these headphones but rarely get to recommend them. But your use case is similar to mine when I bought these. They have become my everyday headphones. Only 30$ now on Amazon.
I believe this would be your best option. Looking at amir's graphs the vertical directivity is even below the tweeter (which would be above the tweeter when turned upside down).
Also I had them upside down for a while with tweeters slightly below ear level. Sounded and measured great. But you...

3. Low distortion giving you headroom to EQ to taste
You can get all 3 for less than $400. Sometimes much less.
