I've tried this a couple of times with girls and I only had positive outcomes of it.

I like taking girls to the park for dates as I love nature and the scenery around my city is great! What I took with me was: my phone, 2 sets of earbuds and a jack splitter. This means we could both listen to the music on my phone. We were walking by the water in the evening and we had a great talk and had some kino going. I asked her if she would like to dance with me and she accepted. From there the kiss was a walk trough the park (pun intended).

Depending on the mood and the setting you could listen to different kinds of music. I thought this was a great way to initiate lots of kino and laughter and I wanted to share it with you guys. Feedback will be appreciated!

Edit: I explained how it can be implemented into a date below.
