Thanks for the comparison!I did listen to a few rock songs with male vocals, and I would feel like they did sound a bit smothered by the rest of the sound. If any specific area sounded that way, it would be the male vocals.
The Blessing 2 is a more clear presentation, with more depth and incisive sound. I think Blessing 2 is more like listening in the mid-to-front of a concert, where the Lokahi is front row. The Mangird Tea is a darker IEM than both of these. I think its the most lush and thick sounding of the three. It's probably the best for long-term listening sessions.
Couple of people have experienced this issue with male vocals...
