Sport, really? Like a previous reviewer, when working out, my iproduct became glitchy. It would start to tell me the artist and song title and then start to go through my playlist, and also the remote volume features would not work.
Let me start off by saying that I have tried nearly every sport in-ear headphones on the market. This includes Beats, Monster, Klispch, Sony, Phillips, and now Bose.
The good - these sound amazing! They blow away the Monster products with the balance sound and clarity. They also stay in the ear securely, and are unbelievably comfortable. On these points, no other brand comes even close.
Now the bad - I bought these this afternoon at Best Buy, and 30 minutes into my run, they started malfunctioning. They would cause my run program (Nike+ GPS) to stop/start, my music to do the same, and Siri to keep asking me "What can I help you with?". How do I know it was the headphones? Well, first off, this is how every "sport headphone" starts to break. Second, it started right after the sweat started to pour off of me (yes, I sweat, thus the necessary water resistant headphone and iPhone case), and third, it stopped immediately after I switched to another headphone (and started again after I switched back)
I just exchanged this pair for another set at Best Buy to give them another chance. I am not overly confident that the results will be any different. I have seen this exact pattern with other brands
