A new advancement in hearing experience

Wow, what to add to the many excellent reviews written here re the new Sennheiser Headphones Well now for me, as a baby boomer who has been spoiled with technology all his life, I must write about my personal experience with this new, brilliant enhancement to my audio life..

The Best
