United StatesReplaced Apple air buds with these for a cost savings and they work really good. They aren’t as fancy as Apple but at half the price it’s worth it. Listening time is better I can listen to music over 8 hours without charging which wasn’t an option with air-buds. Comfort is different since these are hearing protection but I prefer the fit compared to loose poor fitting air-buds that fall out where as these fit snuggly. Only been using for 2 weeks but everyday and can say there awesome. I wear ear protection over them and they fit well in my hearing protection.
United StatesSound was good, and excellent noise cancelation, but to quite being that I have some hearing issues and didn't quite fit right. Did return
United StatesI actually prefer the ISOTunes Extra over the Free, but these perform pretty well. Excellent customer service. I work outside as a framing carpenter in the delta where the humidity is high and thus sweat profusely during the middle of summer, which is when my pair of Extras quit working; likely due to the intractable amount of sweat they were subject to. ISOTunes Audio replaced them free of charge since I hadn't had them a year. Very friendly and warm customer service.
United StatesHe loves them. He says they cancel out sounds great and he can still hear the speakers just fine. He says the other guys are jealous.
United StatesUpgraded from the Pros to the Frees. Love being absolutely wire free. Great fit and sound.
