Sound reception is not good. When you plugin headphone or turn on Bluetooth, then you are on a call or listening to voice mail on your iphone, you might not be able to hear a person’s voivce clearly. Or you might hear crackling, static, or generally poor sound quality.
Compared just to one another, I would suggest getting the iPhone 6s not 6s plus. 6s is more suitable for caring around and one handed use.however if u mostly read text wath video and play game.
Apple iPhone 6s plus style and design are good.
Features are good.
Finally 6s plus is good not better phone.
