Haven't really seen much info about this anywhere yet
http://hearphones.bose.com

It's $500, only available in 3 physical stores

Think of it as an enhanced qc30(which cost $300).
Physically similar, it has two main additions

- more control over NC AND ability to adjust treble (to make voices sharper and hear voices better)
- more directional control over NC, can adjust to hear surround/front/directional(I guess they have more mics in the device to do this filtering)

It's still a new/niche product -
1) if you have difficulties hearing in a loud environment (think bar/reception), hearing aids wont help you , try it out

2) If you want something to complement your hearing aids, it might be useful

3) if not....

it has the same pros/cons of the qc30

From what I understand, theyre still improving the product(firmware, maybe even the physical portions), so you might want to wait until they roll it out to a wider region
