Lightweight On-Ear Headphones

The Panasonic RP-HT21 are wired on-ear headphones weighing 1.2 ounces without the cable. They use a 3.5 mm plug and a 4.5 ft cord for connection. The open-air design suits listeners who want portable stereo audio without bulk.

Simple Plug-and-Play Setup

Insert the 3.5 mm connector into any compatible jack for immediate sound. The long cable threads through clothing or bags without tension. The only common issue is physical wear on the cord or foam pads after heavy daily use.

30 mm Drivers with Extra Bass

The 30 mm neodymium drivers cover 16 Hz to 22 kHz at 16 ohms impedance. The XBS port boosts low frequencies for movies and music. They lack a microphone and will not satisfy users needing noise isolation or wireless freedom.

Questions about this item

How can I confirm the 30 mm neodymium drivers and XBS port are producing sound correctly after plugging in the 3.5 mm jack?

Play audio through the headphones and listen for clear mids, detailed highs and the boosted low-frequency response that the XBS port is designed to deliver.

What comes in the package and is a separate 3.5 mm adapter or cable needed?

The box includes the headphones with their attached 4.5 ft cord ending in a 3.5 mm plug; no extra adapter or cable is required for devices with a matching jack.

Should I choose the RP-HT21 or the RP-HT21M version for a microphone?

Select the RP-HT21M if you need an in-line microphone; the RP-HT21 listed here has no microphone.
