Dyson OnTrac review: Creative design meets unimpressive sound

Dyson is an air company it makes vacuums, hair dryers, air purifiers, and the like. In a way, it's not surprising that the brand ventured into the headphone market, because sound is just moving air in its most basic form. Dyson's first pair of headphones was the Dyson Zone, an $800 system that featured large drivers and an attached air purification system. Now, we have the Dyson OnTrac, a more reasonable pair of $500 over-ear headphones with active noise-cancellation.
