The earphones just stopped working after about a week. I did not misuse them, and had hoped to be able to use them for a long time, but that did not happen. Not sure if this has happened to other people who purchased them or if I just got a bad set. Very disappointed!
I am very pleased with these earphones. The sound is clear. The ear buds are comfortable to wear. I used them to make a phone call, and was told that my voice sounded normal through the microphone, as well. The only drawback to using these for a call is that my own voice sounded somewhat muffled to me. It is still far preferable to taking a long conference call on speaker phone or holding the phone to my ear the entire time. I received this product at a discounted price in exchange for my fair and honest review.
