Hey all,
So I've been looking into getting 64 audio iems for some time now and this drop looks like the perfect time to grab some. Quick question though, is it worth it to shell out a little bit more money for the U6s? I haven't really seen a direct comparison between the two and I'm curious to know how the U6 matches up against the U4SE. Any advice would be great since this is pretty much my first mid-range headphone.

AbaoaquHi Abaoaqu, Twister6 compared U4-SE and U6 in his review of U4-SE: https://head-fi.org/showcase/64-audio-u4-se.22605/reviews

AbaoaquWhat kind of songs are you listening to? If you mainly listen to electronic, modern music, and Jpop (Specifically Jpop), the U4SE is actually a really good option. Otherwise, I think you might find yourself at home with the more balanced soundsig of the U6
Having owned the U4SE and tried the U6, I found that the U6 tend to have a more balanced tonality than the U4SE, and it tends to suit more to the songs I listen to (Mostly jazz, and a mix of old Pop songs as well as rock)

malvinvnvHey @malvinvnv, thanks for the reply. I'm not too much of a Jpop listener, more of a Rock (alt, indie, post), Metal, Jazz & Blues, and a whole bunch of other things, but mainly those. Seeing as you have a similar sound preference, I'm thinking the U6s are better for me as a whole. Thanks again for your insight, it helps my purchase a lot.

AbaoaquNo problem! Glad to help
If you're into it, we actually have some FR measurements down. It's not the best, nor the industry standard (we're aiming to rework the whole database to an industry compliant standard soon someday) But it should help you get a general idea of what sounds like what. Currently we have 325 IEMs and slowly more would be coming

malvinvnvThat would be wonderful, I do love to sift through data so if you have that handy I'd love to take a look through it. It would certainly help with a higher end selection process when I have the funds available for it. Thanks ahead of time.

Green would be the U4SE, and yellow would be the U6.
If you want to see more FR measurements you can check out Crinacle's thread on Head-Fi. He currently has 325 measurements there, and others (myself included) tries to bolster the numbers for quite a while now. I'd like to paste the link here but I don't know whether i'll violate the rules or not
I would also like to add that measurements are not the be-all-end-all method of knowing what sounds like what. Some IEMs are really sensitive to insert depth, and when you go custom or universal it'll change significantly. Furthermore, from one brand to the other, even though FR looks quite similar, they will sound different (especially considering that they might use a different driver setup altogether.
Also, it's strongly not recommended to cross-compare one measurement with the others. Other folks will usually have different measurement methods. Thus, sometimes difference can be found and it's been a main source of dispute among many simply because they don't acknowledge the fact

malvinvnvThanks so much for sharing. How would you interpret the the differences between the u4se and u6 in the 2-4khz region? This to me is one of the biggest differences between the two. For reference, I mostly listen to male vocal rock and prefer a fuller mid with vocals that aren't recessed. Im also somewhay sensitive to sibilance and peaky treble. Thanks!

Jaker782Judging from the graph as well as my experience. I find that the boosted 2-4kHz region on the U4SE gives a more energetic presentation on female vocals and lower treble. If you want a lot of initial sparkle on your songs, these might be good for those who like modern JPop songs. Honestly, i do feel that the tuning of the U4SE is very Japanese, in a sense that it caters to those who loves female vocals. The U4SE shines really well with vocaloid tracks. The U6 in comparison would feel lusher due to the more even ratio of the lower and upper midranges. I'd say, the U6 would be a better all-rounder for most cases. The more even-tempered mids will give more perceived body in the lower mids.
Now, as for your treble, I do find that the U6 has some peaks that gives a more tizzy feeling on some tracks, especially hotly mastered rock songs. Depending on your tastes, they might sound a little harsh if your listening volume is very high, but it's very engaging in a more appropriate listening levels
I would still recommend you to demo these 2 though. If you're in Asia I can point you out to somewhere (Better yet if you're Singapore based haha).
Judging by your preference, the U8 might just suit you better, but I'm afraid you'll find it too dark. Mind if I ask what IEMs/headphones you come from? It will give me a better idea on where you come from and hopefully helps to point out which one's the better option
Just for info, I kind of prefer neutral-ish sound nowadays (HD800 is daily driver at home, UE7 for mobile use while I wait for my UE18+) and I listen to a mix of everything. Currently I enjoy a lot of jazz and acoustic tracks, with an occasional rock songs spicing up things. I try to be as neutral as possible when reviewing, but still. I might just miss a thing or two whenever it comes to comparing things I've demoed
Sorry if it ended up being far too long. There's quite a lot to be talked about when discussing preferences, and these 2 IEMs just have a lot of cool aspects to be discussed as well :p

malvinvnvThe U8 is not in my budget, so I am stuck between the U4SE and U6. The way you describe the U6 lower and upper midranges being more even resulting in lusher vocals makes sense and I am thinking the U6 would suit my tastes more, especially since I only listen to female vocals maybe 10% of the time (which you say are better suited for the U4SE). I think I could use EQ to boost the upper mids slightly, especially when listening to female vocals. The truth is I will likely be happy with either iem, but don't want to settle for the U4SE just because it is cheaper. By the way, my favorite iems are the Flare R2PRO and FLC8s (red-gold-gray filters). I also prefer listening at lower volumes and prefer a balanced sound if that helps. Thanks!
