Lightweight ergonomic shells with MMCX connectors and a braided copper cable ensure comfortable long listening sessions with strong passive isolation.
About iBasso IT01
The iBasso IT01 brings advanced driver technology right into a compact in-ear design. Its 10mm dynamic driver developed in-house combines a 5µm multi-layered graphene diaphragm that stays ultra-light yet stiff with a magnetic flux near 1 Tesla and dual Helmholtz resonators. This setup creates powerful bass extension without sacrificing speed or introducing distortion so listeners enjoy deep impactful lows that feel controlled and natural across many music genres.
Audio performance specifications deliver impressive range and efficiency in daily use. The frequency response covers 10Hz to 42kHz while sensitivity hits 108±2dB at an impedance of only 16 Ohms. Total harmonic distortion remains under 1% at 1kHz and 1mW and the earphones provide -26dB noise attenuation with 10mW rated power handling. These numbers mean the IT01 reveals fine details clearly and stays effortless to power even from basic devices.
Design and build features focus on practical comfort and reliability. The detachable MMCX connector system pairs with a 1.2m 4-wire braided oxygen-free copper cable that ends in a gold-plated 3.5mm plug. Shells weigh just 8g without the cable and offer an ergonomic universal fit that supports good passive isolation. Users can swap cables easily and enjoy secure comfortable wear for long sessions.
Usability aspects make the iBasso IT01 a versatile everyday choice. Low impedance allows strong performance straight from smartphones or laptops without extra amplification. The driver technology balances deep bass with overall clarity and speed so the sound stays engaging whether exploring bass-heavy tracks or more nuanced recordings. This combination helps the earphones feel responsive and enjoyable for extended portable listening.

Reviews
These in-ear monitors surprised me with their deep bass that hits hard yet stays clean. I use them daily on my phone during commutes and the sound feels full and exciting. They sit comfortably for hours without any fatigue.
Swapping cables is so easy thanks to the MMCX connectors and the braided cable feels premium. Bass extension brings real impact to my playlists while details stay clear. They isolate noise well enough for public transport.
Lightweight shells make long listening sessions enjoyable and the driver handles everything from rock to electronic music smoothly. I love how effortless they are to drive straight from my laptop. Great balance of power and clarity overall.
