Excerpt: Our company has a call center and we go through these like candy.These were some of the best kinds we have bought in a while. Very durable and get the job done. No issues with interference with other electronic devices in the surrounding area. We will definitely be buying these again.
Summary: My 5-star (excellent) rating is on the value (quality vs. price) of these. The wiring is a little flimsy, so I don't know how durable they are going to be if they get pulled on too much. But I expect the cheaper construction at this price. These earbuds sound fine on my MP3 player.
