I wanted a pair of Bluetooth ear phones that would be comfortable to wear and secure so I could move around freely without being worried they would fall out or off. I chose these ones as they had three sets of hooks and buds that were each different sizes, my head is quite small, to get hats, glasses and headphones that fit properly I usually have to go for products targeted at children. I opted for the smallest size hooks and buds and they fitted brilliantly. They are simple to set up, and volume can be adjusted easily. I used these earphones paired to my phone, and listened to the radio for a few hours, timers that I set on the phone came through on the earphones. I made and received calls without any problems. Last but not least, the sound quality is really good and even at low levels it cancels out external noises.
