Ever since my dad bought me my nifty Sennheiser's, listening to music has been more of a pleasure than ever. I push the button and the annoying baby that has been screaming at the back of the bus has jumped out the window for all I care. Turn the bass up, rest your head and the rest is history. I'm writing this to all those people who hate those sounds at certain times and cannot find a better solution than sticking their fingers in their ears or using ear plugs. Mine says (on the packet - it is a PXC 150) that it reduces outside sounds by 70%. Don't be misguided however. It's not like the minute you push the button you'll be deaf as a rock. You'll notice the difference though...one that will make your journey and your music listening experience a better one. Honestly people. Go get one. It's worth it.
Thankyou Sennheiser. You make life just a little bit better.
