To be honest, I had a really poor first impression of this product. The low end was very exaggerated, and being in a Rock mood at the time, it didn't sound as good as my other IEMs with the Rock music I was listening to. Due to having less contrast or sharpness. For reference, the other IEMs better for Rock were the OH10 and the Blon BL-03.However I'm glad to say that over time I've grown to love them. The sound is still a bit too low-end heavy for me, but I've adapted to the signature and it's very relaxing to listen to. I can listen to them all day whilst working and not feel fatigued at all. On the other hand if I try doing that with any of my other IEMs, I get fatigued either physically or hearing-wise after a few hours.So I'd say that if you're looking for a good all-rounder, something really really comfortable (I'd say they're my most comfortable pair), not fatiguing, but still very immersive and fast, then go for these. The sound is a bit different to a Dynamic driver IEM, but I've gotten used to them and I like the sound that the armatures bring. I'd assume that with a dynamic driver these'd probably have been awful due to such a heavy low end. But because they're armatures, they don't muddy up the sound as much.If you're looking for neutrality, or detail monsters, I'd suggest looking elsewhere. If you only listen to Rock, I'd also suggest looking elsewhere. But if you listen to a variety of music, and don't mind an all-rounder as opposed to something that stands out only in sound quality and with certain types of music, these strike a good balance between being "safe" and non-sibilant but still being well built and enjoyable to listen to. They won't blow you away, but they're so hard to not come back to when you want to listen for long periods.Oh and they look really rad, they're my best looking IEMs I'd say, having the silver version.
