Overview

The FiiO JT1 is a wired, closed-back over-ear headphone built around a 32-ohm dynamic driver with a 15Hz-30kHz frequency response and 103dB/Vrms sensitivity at 1kHz. It connects over a roughly 150cm OFC oxygen-free copper cable terminated in 3.5mm, with an in-line microphone built into the cable for calls, and FiiO includes a 3.5mm to 6.3mm adapter for use with larger jacks.

Simcoe Audio Video Insight

An in-line microphone on the cable itself means the JT1 works as a practical wired headset for calls on a laptop or phone, not just a pair of music headphones — useful if you want one cable that covers both.

• 32-ohm dynamic driver with a 15Hz-30kHz frequency response
• OFC copper cable with a built-in in-line microphone
• 3.5mm to 6.3mm adapter included

Best for the FiiO JT1: keep the included 6.3mm adapter with your desktop amp or audio interface if you plan to use these away from a phone or laptop.

More Details

Why It Wins

• 32-Ohm Dynamic Driver: Easy to drive from a phone, laptop, or basic amp without extra power.
• In-Line Microphone: Built into the cable for calls and video meetings without a separate headset.
• OFC Copper Cable: A 150cm oxygen-free copper cable terminated in 3.5mm, with a 6.3mm adapter included.

What Makes It Different

Many closed-back headphones at this price skip a microphone entirely, requiring a separate headset for calls. The JT1 builds one into the cable, so it can double as both a music headphone and a call headset.

Technical Highlights

• 15Hz-30kHz Frequency Response: A wide range for a closed-back headphone at this price.
• 103dB/Vrms Sensitivity: Easy to drive from portable sources.
• 355g Weight (Without Cable): A straightforward, no-frills closed-back build.
