Excellent Bluetooth headphones, with constant connection and excellent sound and a perfect fit. I mainly use them when running and connected to my iPhone 6plus or my Apple Watch and have no problems when connecting and the fit is so comfortable and the stay securely in my ears throughout my exercise and they provide an amazing sound which is better than anything I have tried before.

I choose this as a Christmas gift and have been very pleased with the sound quality and the quality of the Bluetooth connection. The only downside is the 'echo' which occurs from footfall but I am hopeful I can address this by changing the size of the ear 'buds'

Good build quality and comfortable. Decent sound quality for the price. But the audio skips one to many times for my liking when I run with the phone (Xperia z5 compact) in my pocket.
