Wired Earbuds for Phones and Laptops

The Panasonic RP-HJE120-K ErgoFit earbuds connect through a 3.5mm jack to phones and laptops. They use 9mm neodymium drivers to deliver a frequency range of 12Hz to 23kHz with 96dB/mW sensitivity. Three sizes of ultra-soft earpads are included for a secure in-ear fit. The 3.6-foot cord threads easily through clothing.

Simple Plug-In Setup With Fit Adjustment

Installation only requires inserting the 3.5mm plug into a compatible jack. The package supplies small, medium and large earpads so you can swap them until the seal feels snug. An improper fit reduces sound quality and call clarity, so testing each size is necessary. The lightweight 4-gram build adds no strain during extended wear.

Check Your Device Has a 3.5mm Port

Verify that your phone, laptop or audio player provides a 3.5mm headphone socket before ordering. Many modern handsets omit this port and would need an adapter not supplied here. The 16-ohm impedance suits typical portable outputs without extra amplification. The cord is not retractable despite some listings suggesting otherwise.

Questions about this item

How do I know the 9 mm neodymium drivers are performing correctly after I plug them in?

Play a familiar track and listen for crisp highs up to 23 kHz and deep lows down to 12 Hz with balanced stereo imaging and no distortion at normal volumes.

What comes in the package and what must I buy separately?

The box contains the earbuds with a 3.6 ft cord, three pairs of silicone earpads in small, medium and large, and a 3.5 mm plug; no adapter, case or extra cables are included.

Which version of the RP-HJE120-K should I choose for my device?

This single model has a fixed 3.5 mm wired connection, 16 ohm impedance and 96 dB/mW sensitivity, so it works with any phone, laptop or player that has a standard headphone jack.
