The cable is insulated with a silvery layer which will green in time due to oxidation
The cable is stiff and slightly rubbery, the bends from being retail-packed has still not flattened out after 5 days of use.
The cable stiffness absolutely requires the ear guides to wear over ear as they absolutely resist staying behind my ear at all. And I hate earguides.
Maybe I'm spoiled coming from Westone cables and Sennheiser IE7 cables which are... light years ahead.
This might just be a deal-breaker the cables.... I might just put them on Sale or Trade and settle with a Westone UM2...
The nozzle articulation is also a tad too stiff. I was almost expecting super flexible nozzle ala Feels Pro 900 which coincidentally is one of the most comfortable IEMs I've ever had. They're not uncomfortable by any stretch of the imagination. Not westone UM type comfy.. but pretty much better than the rest
But if you can overlook these minor shortcomings, this is one helluva IEM. The bass is perfect. The presentation, balance and tone is brilliant.
