Anybody can tell me the difference between Bluetooth V4.0 & V4.1
Got the big sale code on 2 items for Wireless Bluetooth 4.0 and 4.1. But not sure the difference when listenning music or picking up calls.
Suely the 4.0 one is much cheaper.

My friend shared a code for one Amazon UK store who sells electronic items such like: headphones,speakers etc.
I tried it but just bought one wireless bluetooth headphone and one bluetooth speaker, each one with 20% off price.
My boyfriend likes playing video games, so I want to buy a gaming...
