Danny Tan, one of DITA's two founders, explains his earphones by talking about loudspeakers. He told Phile Web that the great high-end speakers he had heard all used dynamic drivers, the cone-and-voice-coil kind, so he built his earphones around just one. Many premium in-ear monitors split the music among several tiny drivers joined by a crossover. Tan feels a single driver playing the whole range gets a natural timbre more easily. Treble is the hard part with one driver, he says, so DITA puts much of its effort into what the driver is made of. Reviewers have noticed. Nic of The Headphone List called the original Dream "the first true reference tuning" in his IEM shootout, and Mykhailo Khilko of porta.fi counts DITA among the few makers that have "solved the riddle of good dynamic driver tuning." DITA suits listeners who want one coherent voice from bass to treble.

The Prelude is the way in. It's an aluminum single-driver set that comes with DITA's ANTE USB-C dongle, which Mahir Efe Falay of Mobile Audiophile felt was designed as its companion. Falay also found that wide-bore ear tips opened up its stage and narrow ones added punch. Above it, the titanium Mecha keeps to one driver, and Nihal of Headfonics praised its "highly detailed and abundant bass." The Project M breaks the house rule by pairing two kinds of driver, and Passion for Sound counted it among the "true giant killers." If you choose the Dream, an early flagship, give it real power. Nic found it needs more than a typical multi-driver IEM, and Audio Rabbit Hole heard it turn thin from a phone at full volume while an Astell & Kern Kann drove it with authority. The Dream also fits shallow, so Audio Rabbit Hole suggests going one tip size larger.

DITA began with two friends who loved audio. Danny Tan trained as a mechanical engineer at the University of Illinois, and Desmond Tan learned the trade in his grandfather's high-end audio retail and distribution business. One of their first earphones, the Answer, was voiced against reference-grade speakers. Danny Tan told Phile Web that its round face came from Singapore coins. During the pager craze, he said, some older people put coins in their ears as earplugs, and the story led DITA to redraw its bullet-shaped prototypes from scratch before production. Small details went in too, such as a tactile nub for telling left from right in a dim aircraft cabin. The Answer won Singapore's President's Design Award as Design of the Year 2015. DITA releases few models, and Kevin Goh of The Headphone List counts it among the founding brands of Singapore's IEM scene, writing that "Dita Audio walked so that Symphonium Audio and FatFreq could run."
