This and that:
Excellent unboxing experience and many premium accessories.
The included case with magnetically closed lid and serial number looks nice but is less dust- and moisture-proof than regular ones.
Both cables are twisted and of really high quality.
Unique and beautiful design. Good build quality.
Sound:
Low impedance sources; largest included single-flange silicone tips.
Tonality:
Unfortunately not as natural and realistic as one might expect at the price point.
Ca. 8 dB of bass boost compared to an in-ear with diffuse-field flat lows (Etymotic ER4SR/ER-4S). Starts around 750 Hz and increases with a hump. Rather warm fundamental range and lower midrange. Starts to lose some quantity below 45 Hz, so more midbass- than sub-bass-oriented.
The mids don't sound realistic. The area between 1.5 and 3 kHz is recessed while the rest above 3 kHz is on a more or less normal level again (actually somewhat elevated around 5 kHz), resulting in vocals sounding somewhat strange and confused. This makes especially male voices appear rather intimate whereas mainly female voices sound distant while mainly bright female voices appear rather intimate again.
Therefore the midrange appears to sound off in terms of timbre and proximity.
Between 9 and 11 kHz, the P1 forms an emphasis that makes cymbal crashes appear splashy. Therefore, they don't sound realistic all the time and can be a bit sharp at times. Sometimes a little sibilant, too.
Resolution:
Decent but not great. Slightly above that of the Sennheiser IE 80, probably slightly above the RHA T20 as well. That's not a big achievement though as the former is quite soft and slow sounding while the latter isn't the most technically convincing either (but a bit above my Sennheiser) and has an uneven treble response.
Around the same price, the Lear LHF-AE1d resolves audibly better and is tuned much more realistically (its bass is softer and slower though), and the iBasso IT01, Fostex TE-02, DUNU Falcon-C, iBasso IT01s and DUNU's Titan models, along with the Fidue A65, perform better on the technical level and are more realistic in the midrange (most are more realistic in the treble, too).
The bass is relatively tight for a dynamic driver and decays pretty fast, however it doesn't seem to have the fastest attack, resulting in it sounding somewhat undifferentiated. In terms of details, it sounds somewhat dull, too.
Towards the sub-bass, the lows soften somewhat more while still avoiding muddiness.
The lows and lower mids appear generally somewhat veiled.
Otherwise, the mids and especially highs resolve pretty well and feature good note separation.
Bottom line: In terms of resolution, I'm not feeling the $199.99 retail price.
Soundstage:
The soundstage is fairly nice: three-dimensional and spacious, open sounding. Wide, with good forward-projection, creating a rather spherical sensation one can easily enjoy.
Instrument separation and placement are fairly precise and clean, while not the cleanest.
Conclusion:
Doesn't convince me for the price. Has some shortcomings when it comes to the tonality. Rather decent resolution for a dynamic driver in-ear, but not among the better ones. Large, open, enjoyable soundstage. Great unboxing experience and cable.
