I'll keep this very concise:   Bass: Punchy, extremely clear, good separation. On of the best iems I have heard for ass response (10/10)   Midrange: Full coloured, precise, dark, warm (8/10)   Treble: Sounded very muffled for this price point. This is where it lets itself down. I listen to a lot of acoustic guitar music, the lack of treble response, extension, and 'shimmer', really hides the details in this genre. This also translates to other genres as well. In Polish Girl - Neon Indian, the lack of treble response really detracts from this...
