The 4.5-feet cord threads comfortably through clothing and bags and reaches the computer across your desk.

Review: Super sound, comfort and price. - I had certain requirements after reading about a variety of headphones. I didn't need a mic, they had to be over the ear not on the ear, clear sound, adjustable headband and wired so I didn't have to use or charge batteries. This headphone checked all the boxes and it just happened to be a company I was familiar with Panasonic. They came today and I'm totally pleased. The sound on my laptop was so low but now I actually had to turn it down. They are very comfortable and super easy to adjust. I could wear them all day. Read about this one. You can get it with a mic if you want. I couldn't ask for a better headphone for listening on my laptop.
Review: Very nice earphones, with mic for cell phone or other uses - They work great and sound good. The lead is long for my use but I cable tied it up and it works fine. I would buy again when needed,

## Questions & Answers

**Q: Do they enclose the ears or press against them? I can't tell how big they are.**
A: With a center hole inside the padding of only about 1 & 3/4's inches around, these do not come close to enclosing my ears.

**Q: Will this headphone jack fit through the headphone jack on my iphone 5s life proof case?**
A: Fits fine through my Otterbox Defender (iphne 5S)

**Q: Down the road, will 2-inch-diameter replacement foam earpads fit these Panasonic headphones?**
A: I just measured them & they're actually oval, not circular. Approx dimensions are 2.25 x 1.75, so they're more than 2" at the longest dimension. You could try them, but more than likely, won't fit. Perhaps Panasonic sells some?

**Q: Will these work well outside brisk walk or running with an iPod?**
A: We only use these on a computer, so I'm not sure how they'll function with movement. I can see them maybe working on a brisk walk, but they might be shaky for a run.

### ⭐⭐⭐⭐ Not so bad but not so good
*by A***Q on January 1, 2026*

They’re not the best but not the worst, they sit nicely on your ears but they itch so much, they sound pretty good but leak sound which is expected, moving the wire effects the sound and connection I didn’t like that. They’re worth 12$ but definitely not more, the design is pretty cool and nostalgic too can’t complain about that. Overall they do the job but not at best.
