iBasso IT04 Hybrid In-Ear Monitor
Best hybrid monitor for audiophiles seeking detailed, balanced sound.
The iBasso IT04 is a hybrid in-ear monitor featuring a sophisticated driver configuration: three balanced armature drivers paired with a single dynamic driver. This combination aims to deliver a rich and detailed audio experience. The dynamic driver boasts a high-magnetic flux and a 10mm graphene diaphragm, contributing to powerful bass and clarity. iBasso's patented internal Root Tube design optimizes the performance of both the Knowles balanced armature drivers and the proprietary dynamic driver. The IT04 comes with a detachable 8-wire braided cable made of silver-plated and monocrystalline copper, terminated with a 2.5mm balanced plug, and includes an adapter for single-ended connections.

Know before you buy
The hybrid setup combines a 10mm graphene dynamic driver for deep, impactful bass with three balanced armature drivers that handle mids and highs. This design allows the IT04 to deliver both the punchy low-end of a dynamic driver and the precise, detailed clarity of balanced armatures.
Yes. While the IT04 comes with a 2.5mm balanced plug for high-end audio players, it includes an adapter in the box that allows you to connect to standard 3.5mm single-ended outputs.
The IT04 provides up to -30dB of noise attenuation. When paired with the correct ear tip size, it creates a very effective seal that significantly reduces ambient background noise for a more immersive listening experience.
The Root Tube design is an internal acoustic structure that optimizes the sound path for both the dynamic and balanced armature drivers. It helps ensure better phase coherence and clarity, preventing the different drivers from interfering with each other's output.
Yes, the IT04 features a detachable cable system. This allows you to easily replace the included 8-wire silver-plated copper cable if it ever wears out or if you prefer to use a different cable type.
