It was familiar because the same thing had happened when Kal reviewed the original Fathom f113 in his May 2007 column. As he would again nine years later, he'd extolled the sub's high power, small size, built-in single-band Automatic Room Optimization (ARO) software, and "remarkably powerful and clean" deep bass. Those were also my reactions to the Fathom f113.

I have had these thoughts many times.

Shots fired!

Sennheiser's new PXC 550 ($399) Bluetooth noise canceling headphone is a direct shot across the bow of Bose's battleship Quiet Comfort 35 ($349) dominance of noise canceling headphones, which I reviewed very positively. Not only do Bose own a big chunk of that market, they consistently, in my opinion, have the best isolation and sound quality performance. Let's see if Sennheiser can put a dent in that armored hull.
