Fuji Labs SQ306 In-Ear Headphones

The Fuji Labs SQ306 in-ear headphones use 10mm beryllium-coated drivers and a 3.5mm connector. They are built for listeners who want detailed audio reproduction from a wired source. The flat tangle-resistant cable runs 4.5 ft and ends in a standard stereo plug. An in-line microphone supports hands-free calls.

Installation and Common Issues

Plug the 3.5mm jack into any compatible audio port and select the silicone ear-tip size that seals your ear canal. The flat cable resists knots but can still snag on sharp edges if pulled tight. The microphone sensitivity is rated at -38 dB +/- 3dB, so positioning the in-line module near the collar improves voice pickup. Maximum input power is 10 mW; avoid driving the 16 ohm load beyond that level.

Compatibility Check

Verify that your device provides a 3.5mm stereo output with microphone contact if you need the headset function. The 110 dB sensitivity works well with portable players, phones and laptops without extra amplification. Frequency response spans 10Hz to 24kHz, so ensure your source material covers that range for full benefit. Exchangeable ear-tips are included to match different ear shapes.

Questions about this item

How can I confirm the 10mm drivers are delivering the full 10Hz–24kHz range after setup?

Play a frequency-sweep test track; you should hear continuous output from the deepest bass up to the highest treble without gaps or harshness, and the in-line microphone should capture your voice clearly during a test call.

Which accessories are included and what must I provide separately?

The package includes the SQ306 earphones with a 4.5 ft flat tangle-resistant cable, 3.5mm connector, built-in microphone and exchangeable silicone ear-tips; you only need a device with a 3.5mm headset jack.

What distinguishes the SQ306 from other models in the lineup?

The SQ306 uses 10mm pure Beryllium-4 drivers rated at 16 ohms impedance and 110 dB sensitivity with a -38 dB microphone, aluminium alloy shell, 2.0 sound track tuning and a 4.5 ft cable — specifications not shared by other listed versions.
