What are the handsfree capabilities on the S7 Edge?

I am looking to upgrade my phone to a Galaxy S7 Edge. Coming from an iPhone a big thing for me is handsfree capabilities. As I work outside being able to use my phone via the headset is extremely helpful. What are the capabilities on the S7 Edge. From using one in store I realise you can now access Google Now via the home button which is a bonus as it has some form of familiarity. Does it go beyond that as my last experience with a Galaxy phone was an S3 which did not end well.
