While not exactly brand new, this week Sennheiser let it be known that ultrarunner Karl Meltzer tones up and tunes out with the Sennheiser/adidas PMX 680 Sport headphones. There are a lot of audio choices out there, but Sennheiser has a point. If Meltzer, who regularly runs 100-mile ultra-marathons, uses the headphones then they probably are something the rest of us might consider.
According to Sennheiser Meltzer runs two to three hours with music playing, and says he appreciates the support of the neckband, which also includes a reflector at the back to provide a little safety.
The PMX 680 also allows him to make volume adjustments without stopping or reaching for his audio player. He can adjust the volume from a clip on his shirt. So for those looking for a new set of headphones, think of it this way, if it works for Karl Meltzer it probably is good enough for the rest of us!
