Our Take:The tia Fourte is the king of detail in an IEM, but the detail is presented in a supremely enjoyable and non-fatiguing package.The tia Fourte is not a reference IEM (look to for that). It is insteadbuilt for unrivaled enjoymentwith excellent bassresponseand beautifully balanced, crystal clear highs. Comparisons to the Focal Utopia are on point when it comes to detail and resolution.

tia System
A tubeless system which includes: tia drivers, tia single-bore, tia acoustic chambers, and a passive radiator system. The absence of sound restricting tubes yields an incredibly smooth and musical frequency response and enables a larger depth and soundstage than the conventional system.
Apex
A revolutionary technology that eliminates pneumatic pressure that causes excessive eardrum movement. Apex (air pressure exchange) relieves air pressure caused by miniature speakers in a sealed ear canal, giving you a superior listening experience that simply cannot be achieved by traditional IEMs.
tia Single Bore
The single-bore design is a huge leap in eliminating unwanted tube resonance. The large bore itself serves as a sound-shaping chamber and aids the tia high driver in delivering a linear and coherent frequency response.
True Phase
ApexTM restores proper phase response at the eardrum by switching from pressure-based amplitude to velocity-based amplitude.
3D Sound
By removing pneumatic pressure from the ear canal, sound is felt to be more spacious and outside the head when compared to traditional earphones.
Aluminum Body
The body of the earphones are machinedfrom a solid piece of aluminum for ultimate durability. They also feature a beautiful matte finish.
