Bestula has just posted a great review on Head-fi of the TH-X00 headphones that have and are dropping at Massdrop. One issue with the review is that bestula appears to primarily listen to the EDM genre so those of us who listen to jazz or classical will need to do some extrapolation.
I joined the purpleheart X00 drop earlier this month and can’t wait to receive them.
Pros: refined, clear, detailed sound with fabulous bass quantity, quality and impact
Cons: non-detachable cables, limited availability, treble can be harsh for sensitive ears
