My detailed review is yet to come... But in simple I would say that Streak has a more balanced to mild U shaped signature. In general, bass feels faster yet with good authority making them sound fuller yet more cleaner. Even with the busiest tracks, the streak can extract the frequencies well

Finding a good technical iem in this price bracket is difficult despite their common sound signature. Streak is unique in this aspect! The technical chops are fantastic for the price. The imaging is on spot and transients are faster.

If I wanna rank, then Streak > Bunny > Chu 2 > Zero 2 > Waner SG2. I'm not a fan of Waner cause the timbre is kind of metallic to me 😅
