These ear buds are great at first and are really good if you want to used them for a computer. However, as time goes on the battery life will take a decline and then the sound quality will begin to become quieter. As I said in the headline I had to contact the manufacturers for them to send me a replacement pair, but I can already see this new pair is declining. Although you can use it for a computer I believe it was made only with mobile longevity in mind. So if your getting it for your phone or tablet its a good buy. P.S. If you exercise with these they may fall out of your ears.
