I bought these solely to connect to my Garmin forerunner 645 music because they are recommended by Garmin and my beloved VModa headphones didn't connect to my watch. The ear bud portion is heavy and I found I had to keep repositioning then in my ear while running or they fell out irrespective of...

Great that the product comes with three different-sized ear-piece fittings, certainly allows for a good customised fit in the ear as they never fall out, but regrettably the audio quality is very poor, especially when taking phone calls (but no complaints from callers about the mic.). The music audio is disappointingly "tinny" so if you are buying them for music you will be disappointed. The regular PB Tech price was $169 and I bought them on a whim when I saw them for $69, so I am OK with that, but would be upset if I had paid $169 for such "tinny" sounding audio.
