135 Crusher Through Put

Sennheiser launched a slew of great new headphones earlier this year, perhaps the most exciting of which is the sennheiser hd 4.50 btnc.We recently reviewed those headphones, and they scored a hefty 8.610, which is pretty good.They, however, also have a smaller and slightly cheaper sibling the sennheiser hd 4.40 bt headphones, which do away with the noise cancellation and cost a good 50.
