Just two things:
The Pros are one of the heaviest and most uncomfortable pairs of headphones around, you're still open to, I'd say 95% of the headphone market if you want something lighter.
And oftentimes high-grade plastic headphones are much more durable than metal ones. Usage of aluminum/steel is nice, but often just gets in the way (heavier, more uncomfortable, prone to more damage if dropped due to weight). In other words, metal=/=durable.
You didn't mention anything about portability, so I'm assuming fullsized cans are okay? Something about music/genre preferences might be useful.
I'd go for the HFI-2400. It's under $200 right now on Amazon.
Portability I'm ok with anything.
Ok so I'll take good plastic.
All purpose, I just need natural purist sound no mods no enhancements no equalizing and no amps.
And I heard open cans have better sound do the ones you suggest seem good. Does this pair u suggested confirm with all conditions so far? Thanks alot.
