What it is

The Ruth's sister 102 is an in-ear earbud headphone with a moving-coil driver and a 3.5mm plug. It ships new and includes a 1.2m cable and a user manual. The semi-open earcups use memory-foam pads and a ferrite magnet for a lightweight fit.

Who it suits

Listeners who want wired stereo sound with active noise cancellation and a built-in microphone for calls or gaming will find the inline volume control and control button convenient. The waterproof rating and 3.7m line length also support sports or outdoor use. Buyers who need wireless freedom or a shorter cable for desk use should look elsewhere.

Deciding specification

The 43 ohm resistance and 123dB sensitivity determine how loudly the earbuds play from a given source. Match those figures to your device output to ensure adequate volume without distortion.

Questions about this item

How can I confirm the 102 earphone is working correctly after plugging it into a 3.5mm jack?

Sound should play clearly through both earpieces with the moving-coil driver, the inline microphone should pick up voice during calls, and the volume control and active noise-cancellation button on the cable should respond immediately.

What comes in the package with the model 102 and what must I provide separately?

The box includes the earphone with 1.2 m PVC cable, memory-foam ear pads, a user manual and a 3.5 mm plug; no extra adapters or cables are included, so any device without a 3.5 mm audio port will need its own adapter.

Which impedance version of the 102 should I choose for my phone or laptop?

The single model 102 covers an impedance range of 33 to 100 ohms with 123 dB sensitivity, so it works efficiently with typical smartphone and laptop outputs without needing a separate amplifier.
