Know before you buy
Most earphones use sound tubes to direct audio, which can cause resonance and distortion. The tia™ system removes these tubes entirely, allowing the drivers to fire directly into the ear canal for a more natural, open, and detailed sound signature.
Yes. The internal apex™ technology vents ear canal pressure, which significantly reduces listener fatigue compared to traditional sealed in-ear monitors. Combined with the ergonomic aluminum shell, they are designed for extended, comfortable use.
The dedicated dynamic driver handles the low-end frequencies, providing a punchy and impactful bass response that balanced armature drivers often struggle to replicate. This gives the tia Trió a full-bodied sound that balances deep bass with clear, precise mids and highs.
With an impedance of 5.5 ohms and a sensitivity of 104dB, these are relatively easy to drive. While they will work with most standard devices, a high-quality portable DAC or amplifier will help you get the most out of their resolution and dynamic range.
The tia Trió provides -15dB of passive isolation. While this is effective for most environments like offices or commutes, it is not as aggressive as the total seal found in some other professional monitors, which helps maintain a more natural soundstage.
Yes, the tia Trió features a 1.2-meter detachable cable. This allows you to easily replace it if it wears out or upgrade to a different cable type if you prefer.
