My wonderful better half got me these for Christmas/Hanukkah. Christmas for her, Hanukkah for me. I listened to them for a while, let them run for a few days and listened again.
They are my new reference. More convenient than my old old STAX, but really, the sound is similar, which must be why I like them. Very fast response. Plenty of very smooth and low but not overpowering bass. Precise midrange, excellent on vocals, a standout on chamber music, quartets, etc. I played some Steve Smith jazz on vinyl and the drums were very good. Traps, snares, cymbal, kick drum. All fine.
Clean world percussion, (Shubendu Battacharia, Tabla Beat Science). Sitar sounds like you’re right there. I haven’t yet found any clean track that they sound bad on.
The flip side is - they’re just a bit heavy on the head, and they are merciless on poorly recorded material.
They are also just a bit power hungry. I can drive them to satisfactory levels using an iPhone/camera card/Dragonfly Black combination, but I can’t make them LOUD with that. A headphone amp is a real plus with them, and not a wimpy headphone amp. Someday, I may buy something with tubes to drive them; I think that would be ideal.
