For those who are looking to get into the Bluetooth headphones/head set market, primarily for working out or heavy use in other than calm scenarios I would steer clear of these. The first set which I posted about died on me about two weeks after I used them everyday. They are not sweat proof and during one session of running they started buzzing non-stop and stopped functioning. They did not charge afterwards. I returned them for a replacement, figuring it was a one off issue except the same thing happened to the second set, on the first run, about two miles in. Literally same exact issue. Returned them and got a replacement again, this time I will limit use to driving and just general use outside of working out. I called LG to see if this was something they warranty and was told that the HBS-750 are not sweat proof or even remotely water resistant, and that sweat or water voids the warranty. Thanks for nothing LG, thankfully Amazon replaced them - Thank you Prime membership!
A buddy of mine told me he has been using the Jaybird X Sport blueooth headphones for sometime and he's a big workout buff, so I decided to give them a try. I will update as my experience follows but as of now, the LG HBS-750 are a no-go for workouts.
