I have to say, for the price I'm loving these. I've had all sorts of IEM's and Headphones from cheap to expensive. Some to mention are Empire Ears Legend X, the P1's, TFZ Live 03, BLON (all of the IEM's), Beyerdynamic TYGR 300R, Beyer 1990 pros, a LOT of Sennheisers and KOSS headphones, Audeze iSine 20's, Audeze Mobius and Penrose (yes I know they are gaming headsets but they perform well), and so many more. I am what I like to call myself a "Basshead Audiophile". I LOVE bass, but I don't want it to ruin the other frequencies. The Legend X did that a bit for me, and to be honest the Legend X tried to make the soundstage too large. I think IEM's are supposed to be intimate, otherwise it's typically artificial soundstage and I pick up on it.
Let's get back to the PMV PP's. They are outstanding. I don't think they are technically impressive as the tinhifi P1's, and by that I mean they don't pick up quite as many details... but in a way they get the same and more. So, what do I mean? Well, the Tinhifi P1's were a bit too dry and sterile, and boy were they hard to drive (in comparison to these anyway). The PMV PP is rich, and full... it has bass. It's not going to blow your socks off, but it definitely has more than the P1's, and it isn't muddy at all, it is VERY well controlled. The bass does leak a bit into the mids, however it doesn't overpower them at all. It's just there, the details in the mids get reproduced and picked out very easily enough. The highs are definitely well done, they don't reach quite as far out there as a 64 Audio tia Forte for example, but they do a very good job. This isn't a HUGE soundstage IEM, but then again... I don't think IEM's should try unless they are open-back IEM's, because then it is a natural expansive sound.
I really love these things, they have a very nice finish and are built well. I ditched the cable though, it's not horrible but I have better ones that feel better so I used one of those. These are VERY good for EQing, they handle everything I threw at them, and the distortion isn't there. These don't take much to power, and hold up well with high volume, something dynamic drivers have a hard time doing. These also sound a lot more natural than the typical planar magnetic. I don't know what it is about planars, but I always felt they didn't have the best timbre when compared to dynamic drivers (sort of like how balanced armatures deal with bass, yes the bass is there but it doesn't feel or sound natural when compared to a dynamic driver).
I absolutely love these. They have the sound signature I love, a good bass reproduction, details everywhere. Very pleasant, they may not be SUPER analytical or MONSTER detail retrievers, and the sound is more of an "in the head" experience versus something you get from an open-back set... but man these tick off so many check boxes that I felt the need to tell people. Easy to drive and able to take power too, nice frequency response, distortion isn't an issue, natural sounding, impactful and dynamic and not a siblant or shouty pair, built well, great price for what you get. I think it depends on what you want, but these are amazing in my book. I think everyone should have multiple headphones/IEMs for different occasions... and these deserve a spot in anyone's collection for being very well rounded and impressive in many areas.
