The Tia fourte is 64 Audio’s flagship earphone, introducing the new Tia driver technology and innovative frequency shaping chambers. The hybrid design of 3 tia drivers and 1 dynamic provide a richly detailed presentation with powerful lows, and fast, aggressive highs. The Fourte can be described as having an emphasis on the high frequencies, and a slightly accentuated low end. Despite the focus on the highs and bass, the midrange and vocals remain intimate and powerful. The addition of Apex technology relieves air pressure inside the ear canal whilst preserving isolation.

The Tia fourte comes bundled with a multitude of tips, 3 pairs of foam tips (S/M/L) and 3 pairs of silicone tips (S/M/L). The high quality included detachable cable terminates in a 3.5mm TRS plug. The package also includes a cleaning tool, dehumidifier, shirt clip, and hard shell protective case. The Tia fourte is finished in a durable anodised aluminium, ready for daily knocks and drops.

The Fourte is best for listeners who prefer a more forward, exciting sound. For a more balanced listen, consider 64 Audio’s U18T.
