I like SpaceMonkey's approach, step away from the open back headphones. What does Amir use for closed backs? I think it's a Dan Clark Audio model. You may want to look into the Drop + Mr Speakers Ether CX headphones. Dan Clark Audio used to be known as
Mr Speakers. Another option might be ZMF closed back. A relatively inexpensive but very good closed back is the NAD Viso HP50. Those may have been replaced by the NAD Viso HP70. But, in that case there are a few good bluetooth headphones at $400 or so.
In general look into closed backs
In fact, HP50 are very good if they fit. I suggest them frequently as refurbished they are super cheap, less than 100usd. I broke headband of my HP50 but I attached cups to a different headphone and they are very good.
The reason i suggest Etymotic Research is because they offer nearly the shortest path between transducer and eardrum. And ER2 have thinner cables with less microphonics so they can be even better value than er3/er4 series. I do have HD600, HP50, LCD2.2, ER2XR and ER4S. ER4S is the most transparent but their cable kills me (as i have to stay superstill). LCD2.2(non-fazor) are really weird and i don't like them at all.
Another headphone which is cool, but rare is Stax SR-001 (or 003 IIRC in modern version). Very light and immediate sound with lots of HF. can be had quite cheap used. light bass though. I still like it and use it often because of sound immediacy and no harshness (although HF is there)
