Bang-for-your-buck sound you just have to hear to believe. The Panasonic RP-HT21 headphones combine a high-quality listening experience with portability and lightweight comfort—and at a price that’s easy on your budget. An XBS port pumps up the bass while a wide headband and foam-cushioned earpads keeps you comfy. Perfect for grab-and-go listening, the RP-HT21 headphones are ideal to keep next to your computer, in your laptop case or in a backpack along with your portable music device.

Lightweight Open-air Design

The RP-HT21 tips the scales at a feather-light 1.2 oz. so you might just forget you have them on. A generous 4.5 ft. cord threads comfortably through clothing and bags and reaches the computer across your desk.



XBS Port for Increased Bass Response

An XBS port magnifies low-frequency sound, delivering full, robust bass similar to what

you’d hear in higher-priced headphones and brings alive your favorite dance tunes or action movies.

Wide Headband and Cushioned Earpads

A wide, ergonomic headband and foam-cushioned earpads feel secure yet never intrusive, while providing hours of listening comfort.


30mm Diameter Drivers and Neodymium Magnets

Despite their demure profile, the RP-HT21 delivers clear, natural sounding

mids and highs along with resonant bass powered by 30mm diameter drivers, neodymium magnets and 16Hz - 22kHz frequency response.

Rated 5 out of 5 by from Just right earphones These earphones are just right and I really like them for me as I have a real problem with ear buds they really hurt my ears. I was very happy to find these on your website as they are hard to find elsewhere. The sound quality is very good and needless to say for the price it is perfect. I wear headphones when I work and these are just what I was looking for. Thank you for carrying them.

Rated 5 out of 5 by from Excellent headphones for the price I tend to abuse headphones, using them both at work and home. I purchased a pair of these several years ago, and they have lasted longer than any other pair I have owned. So I recently purchased 2 more, to keep one at the office and one at home. I must admit though, I am not exactly someone who is an audiophile, so I cannot comment with any authority on the musical qualities beyond that I don't hear any great distortions.

Rated 5 out of 5 by from Awesome head phones. Almost as good as my $300 Bose Quietcomfort 15. I can't wear my Bose set to the Gym as they cover my whole ear and make them sweat, so I bought the Panasonic HT21 and they are a 5 on a scale of 1 to 5. They stand right up against more expensive headsets. I have tow big screen Panasonic Plasma TV's in my house and they are the best.

Rated 5 out of 5 by from Amazing Value If youre someone who likes heavy bass music like i do and want to go easy on your wallet, then this is for you. Sound does leak a bit and it's not noise-cancelling. Ive been using it for over three years continuously. One of the best things ive ever bought.

Rated 5 out of 5 by from Great Quality Headphones for the price !!! I bought these for in-flight headphones instead of the horrible ones they sell for $5 on the plane. I bought 4 pairs and gave them to the family. They we pleasantly surprised by the quality sound output and everyone else that tried them was surprised as well. If I lose them or break them, just get more without hesitation. The reason I tried the Panasonic brand without hesitation is that when I was looking for phone headsets with microphone for work, I tried a bunch of different brands up to about $300, but settled on KX-TCA60 which cost about $10 each...which seemed ridiculous. Great quality...amazingly clear and crisp. I bought a dozen sets and we use them everyday. If we break one, we just grab a new set...not an issue. They usually take about 1 year of abuse before something breaks.
