Designed for expressive listening

These in-ear headphones use a 10mm driver and 16 ohm impedance to deliver a 20Hz–20KHz frequency response. The 3.5mm connector provides universal compatibility with phones, laptops and portable players. A 4.5ft cord gives freedom of movement without excess cable. They suit listeners who want a simple wired connection for daily audio.

Passive operation and microphone clarity

No battery is required for audio playback because the 3.5mm jack draws power directly from the source device. Maximum input power is rated at 10 mW and sensitivity reaches 95 dB +/- 3dB for clear volume levels. The built-in microphone offers -38 dB +/- 3dB sensitivity for voice calls and voice-assistant commands.

Fit options and acoustic detail

Three pairs of single-flange ear-tips are included so users can select the best seal for comfort and isolation. The high-strength alloy shell with brush effect protects the internal components while keeping weight low. A special hollow diaphragm facing downward and a 2.0 sound track design aim to improve acoustic fidelity across the frequency range.

Questions about this item

How do I insert the 10 mm drivers with the single-flange tips so they seal properly?

Choose the tip size that slides into the ear canal without force, twist slightly until the alloy shell sits flush, then run the 4.5 ft cord behind the neck to stop the 3.5 mm plug pulling the seal loose.

What parts will wear out first on the SQ101 and how do I replace them?

The three included single-flange ear-tips degrade with skin oils; swap them when bass drops or isolation falls. The 3.5 mm 4-pole plug can develop intermittent contact — clean the contacts or replace the cable if cleaning fails.

Where does the 10 mW input limit show up during long listening sessions?

At 95 dB sensitivity the 10 mW ceiling caps output near 95 dB SPL; pushing louder compresses dynamics and heats the 10 mm voice coil, so keep average levels below that threshold.
