First,I'd like to say thank you to the Head-Fi community for educating me and enhancing my listening experience.
I recently ordered a pair of ATH-M50s and they're amazing. But they do not isolate/detonate/cancel out as much noise as I'd like when I'm out. I miss my old pair of "Sony Earbuds" (link below). I thoguht they were amazing as they were my first pair of IEMs and first set of headphones/earbuds over 15$... But it's been some time since and I know that there has to be something better than those.
I'm looking for a good pair of IEMs (or just plain out in-ears) under 150$.
