no no no...no bad mids. definitely never said that. the v-shape makes things sound super exciting because the bass and treble is pushed in your face...but it's done very well.
i put the m5 equally at the top of my list for best iem i've heard:
a18 / m5 / elysium / erlkonig
no bad mids...
I need to pull out of the erlk audition before its too late.
I auditioned the Erl as well in my line up. It has quite a good sound I just felt like you had to give up too many ergonomic factors to achieve a sound that... Eh.. it's really good but more or less on par with M5, Elysium, Wraith, etc.
With the Erl - the first thing for me that stood out was the weight. Super heavy in my ears and I had discomfort after less then an hour. For me, price wise and how much I love to actually spend loads of time listening to music.. fit and comfort for hours is the second most important thing. Second only to the sound.
Fit isn't terrible in the ears, but I actually felt the fit in the universal M5s were better then the Erl. And I bought them custom so.. fit could be better on the Erl.
Sound - to me they were much too empty in the low end below the 3rd or full 4 tuning settings for low end. So, if I were to own these, the 1 and 2 settings would basically be useless. I auditioned mostly settling into the full 4 setting I believe if I remember correctly. Everything else was just not as full and dynamic across the spectrum of sound and performance.
Looks - To me, I do not think they look very good. The silver is made to be a bit dull/bleak vs nice sheen and shine. Kind of like 'Matte' Esq vibe to it that I think kills the silver anyway. And the finish is rediculously scratchable. Infact, employee that was handling them for me during the demo dropped them onto the counter, (infront of the owner of the store - funny enough) a 6 inch drop and they got scratched. The silver is much too big of a hassle to be worth much in my opinion.
Price difference - honestly... The huge price gap here is not even close to worth it. Even if price were not an issue for those of deep pockets, I much more preferred the Elysium if you're going with VE. I A/B'd both directly back and forth too. The Elysium immediately pulled me in and gave me a show, the Erl was just, good but nothing particularly outstanding in relation. So even if you've got the spending budget, I don't think the Erl is worthy of choice in the performance vs Elysium or others. Especially considering the Elysium sound would undeniably improve if I had a custom version. With the Erl, I heard the best it'll get since it's only Uni.
This of course is based on my ears and tastes and observations of the sounds and how I hear them with the music I tested and enjoy. Others may see, appreciate, or enjoy things differently
