Pros: Detail, accessories, bass, clarity, durability, cable
Cons: Soon to be discontinued...
I had the GR07s for a few months before I got the BEs secondhand. I loved the GR07 sound and if I had to nitpick and find one thing to improve upon it would be their slightly dry bass range.
Well. Problem solved.
The BEs are are incredible IEM. They retain the all-too-raved-about sound of the Mk II but add a touch of mid-bass to make those modern hip hop, electronic, dance recordings even more fun.
It bears mentioning that the BE is by no means a basshead IEM. There is simply a small boost in the lower mid bass that adds a little in the low end. I couldn't ask for more. I'm very glad I found a pair before they are discontinued.
Thanks VSonic. Bio-cellulose does it again!
