Wired In-Ear Earphones Grey

The No Sew Rider wired in-ear earphones in grey connect via a 3.5 mm plug and weigh 57 grams. They are intended for listeners who want a simple corded option for phones, tablets or laptops without relying on batteries or wireless pairing.

48 Ohm Impedance and 20000 Hz Response

The single specification that decides fit is the 48 ohm input impedance paired with a 20000 hertz frequency response. This combination determines how loudly the earphones play from a given source and the highest tone they reproduce, so match it to your device output.

Suits Commuters and Students Wanting Passive

These suit commuters, students and office workers who value passive sound isolation, a tangle-free cable and an inline microphone for calls. Buyers who need wireless freedom, active noise cancellation or a different connector type should look at other models.

Questions about this item

How does the 48 ohm impedance affect volume and sound when plugged into a phone or laptop?

At 48 ohms the earphones draw less current than lower-impedance models, so they reach comfortable listening levels on most phones and laptops without needing an external amplifier while keeping the dynamic driver under control for cleaner bass.

What does the 3.5 mm connector actually carry and what limits does it impose?

The single 3.5 mm plug delivers stereo audio and the MEMS microphone signal over four conductors, so inline call controls and voice pickup work on any device with a standard CTIA headset jack.

Will the 57 gram weight and supplied eartips stay secure in small ears during movement?

The lightweight 57 gram build combined with the included silicone eartips and ergonomic metallic shells is designed to fit smaller ear canals and remain stable during daily use or light activity.
