I didn't like the original sound of P1....

I did a little upgrade. I extended the nozzle tube (4mm ID, 16mm length) and made a CIEM reshell.

The sound signature is wonderful, similar to the Audeze I4.


The Cayin N8 delivers the perfect sound to the P1.

Woah! Extreme mod!

on Android bluetooth connection, LDAC, to pair with FIIO Q5S (not arrived yet), use which app to equalize?

When I got my P1 the first thing to do was to change the cable to a balanced one for my FiiO Q1 II that has also a balanced output. This was not so practical for checking out its comapatibility with my other amps. So I came back to the cable that Drop had sent with this IEM. Then I saw on the Linsoul web page that they sell a "better" copper cable, the LSC09 for $ 80. Can it be that the Drop supplied cable is this one, it looks the same for me at least?

As I never had a tube amp in any hifi rig I bought a Nobsound Little Bear B4-X made by Douk Audio for the P1. And it delivered: Power galore, even my weak Pioneer XPD-100 DAP now can be used with earshattering levels. Even combined with my cheapo Hidizs Sonata DAC-cable it sounds great. (But of course it helped considerably with the sound signature to find good fitting tips (I have bags and bags of all the different tips). With silikon tips I did not get a good tight fit for a good bass response (only when pushing them in a little bit with my fingers, but this is no solution of course). Short foamies were better but the best bass I get using relatively long foam tips (I do not know any more, where I got them from).
After a few hours of listening to the B4-X I did not run into any hiss or interference problems. It is dead silent when it receives no signal. And because it is no "real" tube amp it does not get warmer that much over time.
My only bigger complaint is the short playing time of only some 4 hours. Worse even, it can only be charged with sedicated charger, no usb connector for smartphone chargers. And it can only play music or get charged.

Funny u say that my balanced cable arrived today!

I paid cheap

Kinboofi 16 Core Silver Copper Cable Balanced 4.4mm

It seems to be of less than or equal to the original quality, with much better braided cable, but I will only be able to test when the player arrives.

I ordered another one in black, cheap for being more discreet. But they haven't arrived yet.

I need to do this mod

 

[Theri0n]

I was told this P1 requires at least 300mW (32Ohm) capable amp to drive it. Is it true?

 

[Infoseeker]

It's strengths are better with such a higher gain. Yes.

But it doesn't sound bloated underpowered either.

 

[dogears]

^True. I'm listening straight from the LG V10 most of the time.

 

[BowWazoo]

Straight @ a Note 9.
Works great.

"I was told this P1 requires at least 300mW (32Ohm) capable amp to drive it. Is it true?"
No: My old FiiO X1 DAP is rated at ">100mW @ 16 Ohm, >65mW @ 32 Ohm, > 8mW @ 300Ohm". And I can only listen to my P1 with roughly 70 % of the maximal possible loudness. My Pioneer XDP-100 has "75 mW + 75 mW 32 Ω". And to play it loud I have to go to its maximum. If I use DAC/Amps it is different: The Topping NX4 DSD has 114 mW on 300 Ω and 293 mW on 32 Ω. But it gets not loud enough for me. There seems to be something else than mere output power.
