Playing uncompressed files via Mojo revealed an entire world of micro detail, dynamic alacrity and bass power that no in-built mobile phone headphone output could ever hope to approach. Playing Fink's "Warm Shadow" from The Walking Dead Soundtrack Volume 1 was a tense, edgy and thoroughly enjoyable experience. As the repetitive guitar theme builds and the rest of the band joins the fray, you'd swear a throng of the undead was, at any time, about to gnaw at your flesh. In other words, the Mojo communicates the digits and therefore the music to your cans faithfully; and in a way that involves you in the experience. Powerful music from Tool and A Perfect Circle just begged me to turn the volume up and rock out. And I did, alas only briefly lest I damage my hearing - you know, paranoia sets in. The bass attack and overall dynamics via Mojo were truly outstanding; every piece of stored music sounded immediate and palpably present.

Now to an important point on this method of functionality. Mojo opens a whole new world for the music-on-the-move generation. Its profound sound-quality improvements over smartphone direct operation will educate the blissfully unaware and expand their musical horizons, hopefully reinforcing our dwindling ranks with a fresh new generation of audio enthusiasts. For that alone, kudos Chord.

Mojo via computer audio. Next I tested Mojo via hook-up to my MacBook via USB (AIFF files, BitPerfect player). Taking out the nevertheless crippling direct iPhone output opens up a Pandora's box of musical delights. Here things stepped up a notch or five to escalate on the ladders of dynamic scale, overall detail and transparency. Bass rhythms propel the music while equal transient snap carries across to the upper mids and highs where the snare cuts through vividly. Mojo's outstanding resolution separated complex musical strands with extreme accuracy, making all manner of detail and nuance easily discerned. Going back to Tool's phenomenal Lateralus release provided significant gains in musical involvement with the power of the guitars, bass, drums and Maynard's visceral vocals walloping the ear canal (again watch that playback volume).

The subtler ambient-rich "Warm Shadow" from The Walking Dead Soundtrack Volume 1, and indeed other tracks from that terrific release, brought forward subtle nuances and ambient cues that the iPhone direct, as good as the Mojo rendered it, just could not resolve. The track's tension was built up even further and the crescendo took on a more manic urgency to a far more devastating conclusion. Much aural pleasure was derived from Seasick Steve's "Fly by Night" from his I Started Out With Nothing And Still Got Most Of It Left release where the subtleties of Steve's vocals juxtaposed with the low level guitar pickings were extraordinarily resolved. The Mojo is quite the tenacious resolution machine. And quality live recordings, from Harry Belafonte's and Earl Wild's cavernous Carnegie Hall productions to the more intimate but equally ambience-rich Anni Di Franco's Live In Clip put you in the concert hall within a ginormous in-head space that's tricked out with reflexive head-turning cues.
