Im using this headset with a Bluetooth connection to a VOIP app on my computer. Pipe I was looking for a specific earphone size, and this was perfect. I purchased these on Aug. The Aonic 50?s arrive in neat and nicely deSigned packaging - it shows off the product and the features really well and gives an indication of the quality of the product inside - you won?t be disappointed. I am going to put sugru around all the pinch points on the wires, though. I have a tiny kitchen with limited counter space. 5-hour shift at work and then some. they slip on well with socks and are for mainly around the house 5 got a 7 and they fit perfect 4th of July here I come??
