Hmmm, that's a bit "how desperate am i wanting to hear them" ahahaha.
Maybe. Maybe not. I'll check some reviews, maybe i'll find some comparisons versus the Timeless.
I have them both, and I can say that they aren't tuned the same at all really. The P1 are more neutral and linear across the board. The timeless has some spikes that stand out... I would say that the P1 are more analytical in nature (even though they are very smooth in presentation), and the Timeless are more emotional.
They both have some good thump in the mid bass, but the P1 have tighter, more controlled bass (though less in quantity than the Timeless). The Timeless are closer to a V presentation with the mids recessed a bit, where the P1 (while not totally forward) have a more even and very clean mids. Neither are really boosted in the pina area. Treble is where the P1 are just tuned better than the Timeless. The Timeless rely more on spikes to give the perception of airyness, where the P1 are fairly linear, making the treble less spikey. Transitions are better on the P1.
If you liked the quantity of bass the Timeless and wouldn't consider less, then maybe the P1 aren't for you. The P1 have the bass, it is just at a lower volume (it isn't missing), and when called for they can get deep. Both sets take to EQ very well.
The P1 have much better imaging and separation, but the staging is about equal (meaning both are fairly intimate). For my ears, there is nothing offensive about the P1 (but they aren't boring). The Timeless had a huge mid bass hump, and a treble spike that could be fatiguing sometimes. The P1 are a lot more clear without ever becoming fatiguing, than they have a right to. Detail retrieval easily goes to the P1 (both macro and micro).
The Timeless are much easier to drive than the P1. You can drive the P1 out of a phone, but you will not get the full potential out of them until you give them a bit more power. Of course this is true for all planar head gear really. Fitment is about the same (for my ears). They both have really short stems. Both stock cables aren't that good, but the P1 is a bit better IMO. The Timeless are about double the price of the P1 (now). The Timeless are tuned very similarly to many of the contemporary planars, where the P1 are pretty different than any other out there currently (though some have tried to duplicate their legendary status).
Sorry for the random(ness) of the paragraphs, I was just trying to type things I thought of at the time of writing this. Bottom line is that you may or may not like them, but as for me, I will not give mine up ever. They remind me of a great set of Hifiman HE400 series headphone in their tuning. This is actually what got me interested in them to begin with. I was looking for a set of IEMs that sound like my HE400S (not the 400SE, the 400, or the 400I), and these come pretty darned close to that.
