So ive been listening 7hz Timeless for couple of days, connected to Fiio BTR3K Balanced and Shanling UP2 (LDAC 990 44/16). While the power output of those might not satisfy everyone, i can say it gets plenty loud for me, my threshold for very loud is around 72db. With fiio been running it 20-28 notches out of 32 depending on level of the song, so there is still some spare for power peaks. On shanling i cant tell exactly as it has 64 levels and no indication, but there is also spare left.
So is Timeless a detailed iem? Yes, indeed it is. In the process of listening to what not from my library, i did a quite a few tone sweeps to make sure the IEMs arent at fault 
but its actually the planars catching few scratchy sounds and mastering inherent clipping that was in some tracks that i didnt notice previously.
Bass is plenty and more than i expected, clean, rumble is there, but some songs can sound bit veiled to my ears. Reducing 1-2 db at 250Hz with GEQ helps the situation for those tracks. That 2hz peak can be bit harsh on certain tracks, especially with female vocals and some instruments that are on the higher registers(like high brass/violin notes or similar).
Using the soft silicone tips that came on the set, as they do fit pretty nice and are sticky so dont fall off the ear. Could be possible not touching the EQ at all but alleviating this with some tip rolling, havent gotten much into this.
As for the sounstage , i find whats already been said mostly true, and was kind of bummed out as i read those comments just few hours before receiving my unit. After listening it i found said stuff to be mostly true, but after receiving it i realized its in no way a dealbreaker or reducing my enjoyment with the set. Worth noting though, is that in the process of evaluating there were some songs that made me think my bluetooth receiver disconnected and sound was comming from the speakers in front of me. So it seems theyre capable of depth, just depends on how the song was recorded i suppose. Ex. athmospheric/reverb acoustic guitar ones are there. One of those songs with depth was David Munyon - Looking at the Rain.
So bit conflicting with what others said, but this is how i understand soundstage and imaging⊠There is a blob that is the soundstage and it can have depth(projected at distance from you)/heigt/width, and then within that blob is the imaging that gives you cues where instruments are. Someone correct me if im wrongâŠ
So with this being said, the 7Hz can have depth in the soundstage(projecting it infront of you and giving you the feeling that sound is comming from speakers), can be felt with that song i mentioned above, and i can hear it in this test pretty clear. Im getting the impression that the sound is comming from my speakers which are about 5 feet in front of me while dong the test.
So depth for the soundstage is there, just within that soundstage theyre not doing pretty good job of giving you the depth position of the instruments(like hints that singer/gutars are in front, drums in back).
Important thing to remember is that soundstage is also a brain thing, what your eyes see your brain will expect and your ears will hear. Since music is sort of an esoteric thing, expectations, mood, blood pressure in your pumpkin will have effect on how you interpret music also. Sometimes some song can sound harsh to you while other times it wont. Same with soundstage.
Ive had times when i was under an impression that iems lost soundstage which was previously there, to have it back at a different point. Im middleaged, so age might have to do something with it, idk, but these observations stand true in my case.
Someone mentioned that they wouldnt be good for watching movies, forgive me for not remembering who it was, but i have bit different oppinion on that subject. Deem them good for the purpose though not without some added help from sound processing. Namely Convolver with following impulses - Dolby Headphone Cinema/Room/Studio and HXR Theater Pro, give pretty good results for my taste, with depth being present and giving impression that youre hearing things comming from your speakers.
The Doors - Riders on the Storm, is imo pretty good demonstration of planar vs BA difference. My first planar set, so it was intersting to hear some pretty stark difference in this example. The second overdubbed track of Jims vocal where he whispers the lyrics sound just in place, smoother and much more coherent with first vocal track, while with BA its raspier/ghostlier and separated. I find do prefer the way planar sounds over BA.
All in all pretty satisfied, though its not without some gripes. Like missing nozzle tuning foam in the package. Ive seen them in some unboxing video, and then there was another unboxing that also didnt have them. Mine already have foam in the nozzle. So did anyone that got them with the foam in the baggy with the spare grills already has the foam in the nozzle? Or those that got the foam dont have it installed, and was left as option to the user?
There were some scratches on the metalic case i got. Same issues were present on the one unboxing available on youtube of the set, the guy had some dings on the iems too which couldnt be from the shipping due to the light weight, and them fitting pretty tightly in the case with the cable.
My case also had some pretty sloppy glue application and streaks of it near the hinge. Material inside is soft enoug and will do the job for protecting the iems, but its pretty thin and will wear out quickly if used frequently imo, also pretty cheap looking. They could have done a better job there.
While not big problem in the larger picture, still brings up some concerns regardind QC, that might or might not affect the iem itself after period of usage. Not the most expensive product, but not cheap either, and for the price i would expect bit more care taken. 7Hz has some space to grow in that area.
Oh, and almost forgot⊠First IEM with MMCX(been avoiding it successfuly so far), and i hate it from the bottom of my soul. And its not that its too stiff, it just doesnt inspire confidence in me, every time i unplug/plug im expecting something to break as compared to 2 pin still much greater force is needed, 2 pin is so muuuch better imo. But maybe ill grow into trusting it, or even liking it, who knows. One of the mmcx connectors on the iem is bit looser on my set.
Havent used the stock cable at all, but switched straight away to, so cant comment on it.
Fit might be a problem for people with small ears, as with my medium ones, the shell touches the inner back part of the ear(is it ear labia?) and causes some pain after long wearing(5+ hours). Imo nicely rounding the edges would have been a much better choice instead of going with the slightly chamfered edges.
Though its not a problem wearing them for 3-4 hours for me, and this is with the small tips that came on the set, so they go in pretty deep. Putting on tips that would make it sit differently/more shallow could potentially eliminate that issue entirely.
With all said, would have i bought them knowing beforehand all the cons i mentioned⊠Yes.
Dont consider this a review in no shape or form, but just few observations that jumped in my face in the short period i had them. Im still high on my iem fix :), so best for few weeks to pass for potentially revised or unchanged oppinions and conclusions.
Pretty short post, EH?
but I really donât mind waiting I donât know way folks get so stressed by it?..a good set is for life so a few weeks wait is chump change
