Okay, so there's a couple of buds in my collection that I like, but don't love. The two are the Vido and the NiceHCK EB200. In some ways, they share a similar DNA. They are both competent buds with a good representation of the full spectrum of sound. Bass represented (very well), Mids good and clear (sufficient), and present enough treble to round out a good balanced sound. My only problem with them is that I consider them to be a bit "dull" sounding. Most likely because the bass section (which is very present) sort of bleeds and floods the sound a bit. I had been thinking about what I could do to mod these things to better suit my tastes. I came up with (and maybe not a new idea) to reverse wire the drivers. I've read that it makes no difference and does no harm to your speakers or amp. The only difference being that when the driver should be pushing outward, instead it pulls inwards. My thinking was that, because of the flimsiness of the driver film, an inward pull would probably create a "tighter" hit than an outward push. I don't know if any of that turns out to be truth in fact. But the results are in and they are very good. A tighter and more impactful bass attack. Less bloat from the bass into the other frequencies which creates a better and more separated space. You can sort of now feel the bassnotes in your throat and acoustic notes become more flavorful. It does not do anything harmful to the other frequencies, if anything, it makes them sound better too. This must be what many modders do to make a run of the mill driver more punchy and distinct. So, maybe I've cracked a nut...
