As stupid as this sounds, I wonder, how loudly does everyone listen their music to?
I might be an extreme outlier, but I consider 80db to be quite loud.
I simply wonder since, after doing some math even a hiby r3 should drive this to my own listening levels, even after accounting for the impendance. And yet, everybody recommends powerful portable amplifiers to drive this IEM.
Thanks for your review!

@Khronos I listen at 60-65dB, up to 80dB with a track I really want to rock out to. Anything louder is unbearable for any length of time. While the P1's specs don't lend to it being that much tougher to drive than your average iem, in use it is a lot more demanding. A phone can bring it up to volume no problem, sure, it just ends up sounding dull and lifeless.

@Khronos Bringing something more powerful into the equation, be it an amp or simply a powerful dap, even at the same volumes it results in a more vibrant sounding product. No idea why, and I don't really care, lol. All I want to do is listen to a product and enjoy it, and if that's what it takes, so be it.

@Khronos it should be fine if u run the P1 on R3 Balanced. P1 had a weird power requirement, it can get loud with low power, but it sounds really bad, the bass dips into the abyss, mid was dry as desert, staging & layering is a mess. When u give it more power, instead of getting loud, it's as if the sound was opened up, the layering & staging is really different. I've tried several dap & amp, u can utilize p1 full potential using device that had about 120mW.
