I found the graphene’s to be a little too bassy and showing less control over other ‘bassy’ earbuds. So I wouldn’t be disappointed in any earbud that has a tighter and more balanced bass response or even slightly less than balanced would be ok.
Ros1 sounds good from your impressions, I wonder if the tonality is warm or more neutral. For reference (of the buds you own) the shozy bk would be considered slightly warm, the graphene’s more neutral.
Either way thanks for the impressions and these seem like an interesting bud. I like the smaller size seems akin to the Auglamour RX1. They can fit really well with thicker donuts or a monk thin and donut over it.
I would say that they are more neutral, than warm.
The major plus points for the ROS1 for me apart from liking the sound, would be the comfort - they are very light and small as I mentioned plus the cable softness.
Getting a donut on was a hoot.
