Nowadays, most people safely use smartphones that emit mostly excellent MP3 player. But when it comes to the theme of sports and jogging the issue in my case, I use instead of the combination Smartphone + Spotify + bracelet for long runs also like the Garmin Forerunner 610 + combination Ipod Shuffle for runs up to 10km. When running the special selection of songs I do not care so much or I'm just before a playlist and these can be accessed conveniently via VoiceOver. So I'm on some albums and genres a few playlists and you're done. If you are traveling with an iPod Nano, you have to interrupt the running for changing the playlist in my opinion. This is not necessary when Shuffle. It also comes with minimum weight and size and can be mounted on top of the T-shirt collar with a clip. The sound quality and the processing speaks for itself. For use in the fitness center you could also use an iPod nano with clip holder to have the option during device pauses to change title. But here you are well served with the Shuffle. MMn makes iPod shuffle all in all the best MP3 player for under 50, which is currently having. This "1/2 full tank" is well spent. When headphones I recommend the Ear Pods Apple, possibly with remote control. These are perfectly adequate and I noticed while jogging not from the ears. 5 Stars!
