Wired In-Ear Earbuds for Phones and Laptops

The Panasonic RP-HJE120-K ErgoFit earbuds connect through a 3.5mm jack and need no battery or wireless pairing. Three pairs of silicone tips in small, medium and large sizes are included so listeners can find a secure seal for commuting, desk work or light exercise. The 3.6-foot cable threads through clothing without pulling.

Ergonomic Fit and Durable Cable

Soft earpieces conform to the ear canal and stay in place during movement while the long cord resists snagging on bags or jacket zippers. A proper tip size is essential; if the seal is loose, bass response and overall clarity drop noticeably. The lightweight 4-gram construction adds almost no fatigue during extended sessions.

Passive Isolation and Efficient Drivers

With no active noise cancellation, isolation relies entirely on the physical seal of the chosen tips. The 9mm neodymium drivers deliver a frequency range of 12Hz–23kHz at 16 ohms impedance and 96dB/mW sensitivity, so portable devices drive them to loud volumes without distortion. Maximum input power is rated at 200mW.

Questions about this item

What does the 3.5 mm connector support on this model?

The 3.5 mm plug carries stereo audio only; there is no microphone or remote on the cable.

What ear-tip sizes come in the box for the RP-HJE120-K?

Three pairs of silicone tips are included — small, medium and large — so you can match the buds to your ear canals.

How should the earbuds be inserted to get the correct sound and fit?

Choose the tip size that seals snugly, then push each bud straight into the ear canal until it sits flush; a loose tip breaks the bass response.
