I am disappointed because although sound quality is good the earphones continually fall out of my ear due to the weight on the back of the neck, it pulls the earpiece's downwards.

Initial pairing of the headphones with my device was problematic requiring at least three attempts. I have also discovered that my Windows 8.1 laptop does not recognise the headphones if they are turned on after I boot-up; I have to make sure that they re turned on prior to booting.

Easy to use, connected to PC and android first attempt. The chord that connects the 2 ear pieces are weighted in the centre keeping them from being pulled out of your ear. Sound quality is average, but the price implies that is what you would get.

Reliable , although had a few issues connecting to Bluetooth at times. Generally have to switch device on then switch on Bluetooth , or remove device and reconnect on Bluetooth list. This is on an iPhone 5.
