These are inexpensive replacement earbuds for your MP3 player, CD player, or most other portable stereo devices. It has a standard 3.5mm nickel plated stereo mini plug. I bought these as replacement earbuds for a portable radio and MP3 player which I use when gardening and jogging.
I was attracted to these earphones by their low price and 'Lifetime Warranty'. Of course, the warranty does not apply to normal wear or damage due to accident, abnormal use, misuse or neglect. However, the Maxell name and warranty probably give some degree of comfort that your eight dollar investment is well spent.
I can't honestly say that they live up to the 'Soft Comfort Fit' indicated on the package - as a matter of fact, I would probably say that they are pretty hard and not very comfortable at all (they certainly don't conform to your ear canal). The sound quality is fair to decent, but definitely not for audiophiles (but what do you expect for $8). These are just decent replacement earbuds, that you don't need to worry about losing or getting stolen if you leave them on the desk in your office.
My Jelleez earbuds are 'Black Licorice' in color (they don't seem to really have any smell or taste). Other available colors are Blue Caribbean, Red Chili Pepper, Green Apple.
I neither love nor hate my Jelleez Earbuds, but they were inexpensive and do the job.
