Sorry it took me a few days. My initial impressions of the Believes below. Please pardon my inexperienced descriptions of the sound, got into the hobby around July and I am still learning the lingo.
So, after listening to the Be-lieves for a couple of days, what comes to mind immediately is detail and clarity. I feel like these are quite a detailed set, especially in the mids and the highs. Even at lower listening levels, the detail still pops out. I have seen some frequency response graphs on the Believe, and I think they sound a little different than what some graphs suggest. I don't feel like it is that big on the bass, and I don't feel like it is really much of a v-shape. The mids are superb, and vocals shine. The highs are extremely detailed and clear. I don't have any audio gear to run them off besides the Qudelix-5k, the usb-c apple dongle, and my phone, the A8 (still has an audio jack), and I feel like the Believes do sound a little better off the Qudelix-5k; not that it sounds bad on the other sources, I feel like the bass gets a little tighter, maybe a tad more separation and detail? I have no problems with getting enough volume, although I don't really listen to music at that loud of a volume, but time spent listening is pretty high.
Although sometimes I hear a wrinkling sound on the left side, maybe it was flex or something due to the pressure? After a long listening session today, I lost volume on the left side for a bit, and when it came back, I lost volume on the right for a bit. Side effects of driver flex? Hasn't happened again, and now I am more cognizant of too much pressure building up. Any ways to try and alleviate this? I noticed on
@kmmbd's review of the Diamond (same/similar shell if I'm not mistaken) driver flex is also mentioned. Perhaps it was due to tip choice, as there is a vent on the rear of the nozzle itself, near the shell, and the long "skirt" of the Final E tips had an affect? Went back to the Radius Deep Mount tips (wider bore like the stock tips) and haven't had any more issues.
However, I am still extremely pleased with the Believes, all things considering as I bought them blind on 11/11. In my eyes, simply great value for the sound quality; I paid around $160 maple (Canadian) dollars for my set, and I couldn't be happier.
Haha, I've worn these for most of the day, I think my ears need a rest.
