ANDROID/IOS APPS
There are two apps you can download and install for the Sport Pulse Wireless Earbuds, the Jabra Sound app and the Jabra Life App (if during setup you can't calibrate/detect the heart-rate monitor skip it and use the app - it happened with one of our smartphones but the heart-rate monitor was detected fine when we used the app).
The Sound App can be used with most Jabra Devices and not only does it give you 16 equalizer presets which you can use (Blues/Classical/Country/Dance/Electronic/Flat/Hip Hop/Jazz/Jungle/Latin/Metal/Pop/RnB/Rock/Speech/Urban) but it also allows you to create your very own.
Moving onto the Jabra Life app things are much more interesting since this works directly with the heart-rate monitor and your smartphones GPS (it also offers a battery charge display) to produce accurate workout data (distance/time/heart rate/calories/cadence/pace) from a wide selection of activities (running/cycling/walking/cross-training/hiking/skiing/skating/spinning and treadmill exercises).
