I just purchased these headphones as well after reading the reviews and comparison guides here on headfi.org. These are my first high-end headphones, and I have been very pleased with my decision.  This is also the first headphone that I have been able to create a seal with the earbud in my ears.

Thanks. I consider this useful and valuable.

I am new to this forum, however I researched IEM's heavily on here before my purchase.  I narrowed my choices to the Yahama EPH-100 and Future Sonic Atrio MG7 Pro. I decided on the EPH-100's and thus far, I am currently very pleased with my decision.  I love they seal they make in my ears...
