Got the P7 yesterday!
When I got them out of the box and tested them I was like: What is this crap? I thought I had bought a $10 portable subwoofer for my head. What a rumbling mess. At low volume the vibration was so big that all I heard was parasitic plastic noises.lol
I figured they needed a burn in, either that or everyone else was crazy for recommending these.
After 3 hours playing some Psychedelic Trance and RAP things started changing a bit. The Bass became more controllable, some Wu Tang tracks were just impressive in the bass department.
Anyway, I left my Xduoo X3 playing pink noise the entire night, by today's morning they sounded better but not much different. Later in the afternoon I let them burning in with more Pink Noise, this time on my Clip Zip at high volume. When I got home from the Gym 3 hours later they were already a different beast. All the sub bass is tamed, bass is very controllable, the mids are starting to show, the highs are getting smoother. The weird thing is that some tracks now seem to be lacking a bit of bass/kick.
I'm not a fun of sub bass, I like clean impactful kick on my ears. I like to be able to give a shape to the sounds. I like the kick to sound/feel like a huge ball hitting me and not some earthquake so I'm hopping the P7 will go in that direction after more burn in.
Overall I'm pleased and optimistic about my purchase. I've heard these need at least 20hours burn in and around 200hours to truly shine so I'm very hopeful.

They match very nicely with my rockboxed Clip Zip (fuller sound), not so much with the rockboxed Xduoo X3 for now. The Xduoo X3 runs much better with the Yamaha EPH-100. In fact I I used to hate the Yamaha's until I got the X3, they have near 0 treble with most DAPs and DACs but seem fine with the Xduoo X3.
The other Heaphones I have are:
Sennheiser HD25 II : The P7 are already better (except mids)
Fisher Audio DB-02 MKII: P7 wins in everything except detail retrieval. Can't stand the DB-02, weird hollow artificial mids that completely trashed 97% of my music collection. Had to increase bass +6db and Treble +2db just to be able to use them with normal music.
Philips SHE3590: These were my go to iems for the last 3 years. Can't beat these $10 pearls with much, amazing V shaped sound signature for the price and still ahead of the P7 in most tracks because of it's sparkling beautiful treble, makes the music sound so stereophonic, tiny sounds flying everywhere. I'm hoping the P7 gets more similar to these pearls as the Burn In goes on else I will return or sell them because right now the treble sounds too recessed to me (need to raise Treble +6db on my rockboxed Xduoo to get to the level of the Philips (oh, and I'm not a Treble head, I can't stand the harsh highs on the BeyerDynamic T90 for example). The Bass in the P7 is already much better then the Philips at this moment.
In conclusion: If the Burn In goes as it should and Treble opens up these P7 will be fantastic. If not I'll return them or sell them and get a Audiophile over-ears version of the Philips SHE3590 if that even exists. Hope so, but i haven't found it yet!!!
ps: I'm also thinking about getting the Chord Mojo, hoping they make a good pair.
