I bought this as an "upgrade" from my Newport H2s and these are SO much better. (I am not certain, but there might also be a way to somehow track the iTrack with an iPhone. no issues. Now that the initial problem with connectivity has "resolved" itself, I can say that connection and pairing of these buds is very fast, very strong, and very reliable. These are maybe even more comfortable than my last pair, and are fitting for both casual and more formal wear. Im married, so Im done filling other holes anyway. Pairing was always a struggle, and once it was, it never stayed connected (despite the firmware update that specifically said it addressed that issue). Just be sure to get ALL of the stickiness off and have a clean surface to stick these onto. I wanted a speaker for my laundry area and this was perfect! Leider MFG
