I will declare these the best ear bud speakers that I have heard and own. Better than UE TripleFi. Better than the regular Turbines. Monster is the best when it comes to including ear tips of all shapes and sizes. I love their silicone triple flange. Love it. Comfy and seals great, but every user is different.
That said, I still think the regular Turbines is what I would buy given the choice. The Coppers are more refined, more open, with very delicate and revealing highs--but the regular turbines are 90% of the sound at less than half the cost.
