SONY introduces the exciting new h.ear Headphone line with the eye-catching MDR-J10 Orange model. These chic Headphones are the ultimate in comfort, with a headband-free clip design that follows the contour of the ears, and vertical in-the-air Driver placement.

Lightweight and secure enough for vigorous active use, the MDRJ10 headphones--part of Sony's h.ear line--feature a comfortable, vertical, in-ear form, a clip-on fit that follows the contour of your ears, and a stable, non-slip design built to withstand exercising, skating, dancing, or other sports. The MDRJ10 earcups use an open-air design that lets you hear ambient sound.

The MDRJ10's clip-on design is hair-friendly and keeps the size of the headphones small. Their tangle-free storage cord is adjustable, making for easy storage in a backpack, briefcase or purse. The headphones come with a 3.5-foot cord, and their L-shaped plug is tailor-made for active use and won't bend and break like an upright plug might.

This headset is ok, but as a backup pair only: the earpieces don't go very deep in the ear so the bass is very weak.
There is also no clip to tie the dangling cord to clothing with, so it flaps around during exercise.
Finally, the orange color is really closer to pink.

just excellent. Over the years I have owned 5 or 6 pairs of these. I use them for lifting running and sleeping. They rock.

I bought this on seeing "4 Star" rating in Amazon.com. It was pretty good when I bought. Now I could not hear any sound from my right side headphone. Very disappointed on the quality from Sony. Be aware when buying this.

I bought these earphones hoping they would stay on my ears when I was working out/running. Unfortunately they keep sliding off and I have to constantly keep pushing them back on my ears when I'm running. but maybe that's just my ears...

these headphones are simple, hold their place, and sound crisp. The only downfall is they are not adjustable for smaller ears or flexible to fit around different shaped ears.
