Ultrarunner Meltzer Standardizes on Sennheiser PMX 680

February 02, 2012


Ultrarunner Karl Meltzer uses Sennheiser Adidas PMX 680 for sound clarity, durability and comfort.

Meltzer has been running ultra marathons now for 15 years, and holds several records including the most 100-mile trail race wins on Earth (30) and most 100-mile race wins in a year.

The runner notes that music is an integral part of his 100-mile running regimen, and to accompany him along the way, he has standardized on the Sennheiser PMX 680 Sports headphone.

According to Meltzer, he tried many headphones from other manufacturers and after evaluating his option decided on the Sennheiser/Adidas PMX 680s. 

Established in 1945 in Wedemark, Germany, Sennheiser is a manufacturer of microphones, headphones and wireless transmission systems.

Company officials note that while Meltzer is able to have clarity and sound quality, the Sennheiser Adidas PMX 680 also offers a new level of comfort and durability not typically found in a sports headphone.

Meltzer said he especially appreciates the support of the neckband and the inclusion of a reflector on the back as an added safety measure.

“They feel very secure on my head and fit into my ears just right,” says Meltzer. “I can barely even feel them, and that’s the whole idea.”

Meltzer uses the PMX 680 to make volume adjustments on the fly thanks to the product’s dedicated volume controller that easily clips onto his shirt.

“It’s important for me to have great sounding music but I don’t want to have to fumble with anything while I’m running,” he adds.
