Query: Very Disappointed

I must say that I was cautiously optimistic in ordering this based on the previous reviews, but it turns out that my experience lines up with the majority of the "1 star" reviews. Like the rest of you, I really wanted to like this product and am incredibly disappointed that I am being forced to return it based on product performance. I bought these to use with my kindle fire at work so I wouldn't be stuck in one spot like I am with wired headphones. However, the hiss that everyone mentions is prevalent even at very low volumes. Turning down the volume on the headset does reduce the hiss, but you have to turn it down so low that I can barely hear what I am listening too, even with the volume turned all the way up on the Fire. I got them today and I have already initiated the return process.
