Pros: High tech, unique, build quality, even handed sound.
Cons: Hard to drive properly, heavy and awkward, no real magic.
I am glad I got these, but I was reading a hype train from 2012. These are two micro drivers and a sub; sounds good, right? But good is not good enough. Especially at these prices and the amazing competition currently out there. They don't stay in my ears easily without a shirt clip. The Y junction is heavy for an iem. I have better sounding JVC iem for less money, but less comfortable.(HA-FXT200ltd)
They can handle a lot of sub sonic signal without distorting. The mids and highs seem separated and unaffected by each other or the Kelvin sub out back.
In closing, if you want to cut 6th period and smoke a fatty at your friends house and listen to his dad's awesome floor system for an hour, these are your babies.
If you want to get blown away by high tech iems, maybe check out the HA-FXT200ltd.
PS I am listening mainly to Trap, Bass, and EDM; not orchestral.
