Sonique SQ306 In-Ear Headphones

The Fuji Labs Sonique SQ306 is a white in-ear headset built for daily music listening and hands-free calls. It uses 10 mm beryllium-coated drivers to produce a dynamic sound stage with clear vocals and full treble. The flat, tangle-resistant cable runs 4.5 ft and ends in a 3.5 mm plug. An in-line microphone handles voice pickup for calls.

Wired 3.5 mm Connection Limits

The 3.5 mm analogue jack works with any device offering a standard headphone socket but provides no digital signal path or onboard processing. Passive operation draws a maximum input power of 10 mW at 16 ohms impedance, so output volume depends entirely on the source device. The specified frequency response spans 20 Hz to 20 kHz, while manufacturer highlights cite a wider 10 Hz to 24 kHz range. Microphone sensitivity sits at -38 dB +/- 3 dB for voice clarity.

Fit, Cable and Compatibility Notes

Three sizes of silicone ear-tips are included so users can swap for a secure seal that reduces outside noise. The flat cable design resists tangles during storage and pocket carry. No software, drivers or batteries are required for audio or microphone function. Buyers whose devices lack a 3.5 mm port will need a separate adapter, and those wanting wireless freedom should consider a different form factor.

Questions about this item

How do I choose between the listed frequency ranges of 10Hz–24kHz and 20Hz–20kHz?

The 10Hz–24kHz figure is the manufacturer highlight for the Beryllium drivers; the 20Hz–20kHz spec is the standard measured response. Both describe the same SQ306 hardware, so pick based on which range you trust for critical listening.

What does the 110 dB sensitivity mean when I plug these into my phone?

At 110 dB ±3 dB, the SQ306 will play loudly from a typical smartphone jack without needing an external amplifier, and the 16 ohm impedance keeps current draw low for portable devices.

What does the 3.5mm connector cap in practice?

The 3.5 mm plug limits you to analogue stereo output and the in-line microphone; it carries no digital audio or remote-control data beyond the mic signal on the 4.5 ft cable.
