Hi all, skeptical on the sound, find the mid-range quite forward and lacking details in the highs and lows. I have tried with and without DAC/Amp (Xduoo 05). When compared to the 1More 4 driver they sound really lacking life and details. Furthermore it might be the cable but with 0 volume they produce a buzzing sound that you don't hear if music plays but at 0 level there is some sort of white noise/buzzing sound that is quite irritating. So not the best purchase in my case to be honest ...
JT44I'm surprised to hear you have an issue with Buzzing. Mine are very quiet but are pretty sensitive. If you have a player with a higher impedance I could see how you might get some hiss but not buzzing. I find them to be fairly neutral. if you are hearing en emphasized midrange then the bass and treble may sound subdued. I do find the bass a bit thin but not unnaturally so. It's present but not heavy like many like it. Great value. Maybe they just don't suit your taste or are defective.
CyberthingyI'm more in your camp with my initial opinion of these. These are very efficient. There is some hiss even on modest amplification like the Bluewave GET. I almost seems like floor noise & it was even worse on bigger amps. Dead quiet directly into my phone though.
I am finding the frequency response to be slightly on the brighter side of neutral. There is some emphasis in the upper midrange & treble. Interestingly enough, there doesn't seem to be enough air around cymbals & such but it does seem to be improving as they burn in. The bass is present although there is no usable sub bass & I do detect a slight hump in the mid bass.
What I have discovered is that though these feel like CIEM's, you have to be sure to get a good seal in order to experience their best. When I say a "good seal", I mean almost "vacuum-like". Even with that you better be sure that you've got them lined up properly with your ear canal. It make a world of difference.
Not sure about the durability & QC claims as mine have been rock solid. In fact, they still look like they've just been taken out of the box.
My pair needed 200 hours of burn-in before I began to feel that they "matured" . Right now, the bass is quick & extended but it's not the strongest. The treble has developed some air & is very good without being sibilant. The midrange, which was always the strong suite, remains so & the small issue I had with the upper midrange has dissipated. They are a very neutral iem. Because of their comfort, fit & ability to isolate, I'd call these my main everyday travel iem's. I have many others that I also use so no, it's not a matter of me getting used to their sound. They really have improved over time & to be honest, I'm not sure that they've finished improving.
Dynamics are not the best & they don't like to be pushed to hard. Keep them within their comfort zone & they can be very good.
To summarize:
Very neutral with a monitor-like presentation.
Best passive noise cancellation of any iem I own.
Very efficient but not the best dynamically or volume-wise.
