And you're all gonna DIE! Muhahahahaha!!!
Seriously, You're probably not gonna live long even if you survive......
I've heard the Ocharaku before. One with silicone tips and one with foam tips. I would greatly avoid using with silicone tips. The treble is unbearable but when I used the foam tips, it is much nicer with a very well defined treble. Yes, looking at the graphs, they look like they're going to cause ear bleeding but it's not the case. It's airy, smooth, natural and not tizzy. I would think they have treble like the HE-500 but more pronounced.
I love math! I am just into practical applications of it, such as heat transfer, and fluid dynamics. I graduated from Wentworth Institute of Technology in Boston with a Mechanical Engineering degree.
