How heavy are the Mo-Fi headphones? Well, Gizmodo says they’re “a little cumbersome to port around” and “I'd never choose them for the train on my daily commute.” The Guardian calls the design “ostentatious” and says “you really feel the weight” when moving about. The trade-off is a better fit on the ol' noggin, thanks to a flexible design that “allows for a surprisingly customizable and comfortable fit,” according to Sound+Vision, who “didn’t have any issues” with comfort after a long listening session. PC Mag finds the Mo-Fi set “pleasant to wear for hours without discomfort” in spite of its “chunky, visually hypnotic design.”
However, all the heft and bulk is there for a reason. Blue builds an amp right into the Mo-Fi to give your phone or tablet some extra oomph while cranking out tunes. This is controlled with a switch simply labeled "On" and "On+." Naturally, the one you use will vary based on your musical choice, but The Next Web finds the sound “balanced, yet powerful” and Android Police says “they produce amazing audio.”
Blue’s first pair of headphones manages to deliver great sound from your portable devices, except that they’re so big you’ll never want to bring them with you. With a price tag $350, they’re a bit tricky to recommend when cheaper, more convenient-to-carry options are out there.
