I'm not going to start any opinion wars here. ALL that I can tell you concerning these new Xiaomi is that if you don't have the proper tips, and have used them for a PERIOD of time, and have concluded they are just average or so-so....
Then you are doing yourselves a great disservice. I just had an 8 Hour listening session with my Pair that now have 99 Hours on them.
These Xiaomi are WAY better than you guys seem to be giving them credit to be. I can safely tell you that Initial impressions on these which I posted previously don't mean Squat.
Don't get me wrong, they aren't what most would call Audiophile, they have a U shaped EQ, with a shorter leg on the Treble side of the U, and yes, the low and mid bass are boosted. But they still are a very pleasant listen. The Bass is no longer bloated or boomy, it is tight and fairly fast with a Tiny bit of bleed over into the lowmids, (something quite common with earphones with EQ boosted bass frequencies). They are no longer Dark. In fact I had to change tips because they became ridiculously bright, with the stock tips. The mids in the vocal range have stepped forward from a V to a U and are now no longer hidden or masked by other frequencies. The Treble from the B/A has stepped forward and is quite nice. Not Sharp or spikey but definitely noticable.
At First, I rolled 5 different tips Stock, Auvios, Spinfit, Trinity Stock, and Sony Hybrids. Out of those the Stock sounded the Best, IMHO. I then started burn in and left them to cook. At about 65-68 Hours I tried them for a Quick listen. I was Floored. They had become insanely BRIGHT.
Same Material, Same Source, Same Tips. Same exact insertion and axis rotation in Ear canal. What would you conclude?
Same as I did. the EQ had changed. OKAY. My GO TO eartips are Sony Hybrids and Auvios as they tend to sound good on a Vast majority of IEMs in my personal experience. I don't use foamies as I just can't seem to get them to sound consistently the Same no matter how I roll them or insert them.
The Clear winner (no surprise really) Are the Auvios. They are Heavier silicone material, Hybrid Large Bore centers. I tried the Mediums and although they sounded great I was experiencing some seal leakage. So I tried the LARGES.
