I bought these two weeks ago. I liked them because they're compact. The sound quality is very nice for something so small. The noise cancelling works great too.So why two stars?For starters, the noise cancelling unit is very sensitive to interference. If I put the stick next to my cellphone in my pocket, it creates a very loud, constant popping noise.Worse though is my headphone is broken already. I only use this around the house, but the plug is very weakly designed. Most headphone jacks are curved or made out of hard plastic.This one is long, narrow, and wrapped in rubber. So it took about two weeks of casual use for the headphone jack to completely come off.I'm sad.
