Works great: The headset works great with all Bluetooth enabled mobile phones. The earphone supports all music applications for iPhone 6S plus.
Sound quality: The people on the other end could hear me clearly and loudly. They said that my voice is pretty good. That praise being said the build quality of this headphone is enough at best.
The battery: The battery of it lasts 12 hours for even long time use. I've used the headset for an hour one day for 7 whole days, and it still shows almost full on my iphone.
Compatibility: Some applications do not support the headset while using samsung galaxy s6. The headphone supports all music applications for iPhone 5S.
Good shape: This headphone has a nice look. This headset is exactly a sports headphone.
I would definitely buy the same. I would recommend it to my friend who needs a Bluetooth headset for his iPhone or other Bluetooth enabled cellphones
