Absolutely horrible. Only my headphones from my 1987 Magnavox Walkman have been worse.
Not only is the sound from these earphones lacking decibels but there is absolutely no bass. The rubber ear pieces do nothing to help.
Then, you have the constant readjustment since they don’t fit snug. And when you readjust, it automatically pauses. No wait...sometimes it fast forwards. Sometimes rewinds. And worse of all, if you dare touch them, it will call the last number on your phone. All depends on the mood of the earphones.
Save your money. Good thing I’m donating many things to charity soon. I’ll do the same with these. Perhaps someone will have better luck than me.
