I was looking for a good helmet for a maximum budget of 100 so I selected the "Pulse" and until today I'm very happy with one point is reviewing the foam under the arch is not enough thick, like helmet weighs 330 grams after a while it becomes a weighing can not I give it 5 stars. Under PC AND MAC PS3 you can use it with USB key but with Android 4.4.2 Galaxy Note 3 headphones are not recognized Bluetooth therefore obliged to use the cable that is removable, but you can use voice commands with the native music player to take a call, reject a call, next song, previous song increase and decrease the volume and play and pause. The various sliders and buttons are easily accessible Being a fan of Jazz / fusion but with eclectic tastes I was looking for a helmet that renders excellent midrange treble sound quality and bass and that's something you would not talk faite.Je option Bass impact because for listening to music as I am offered and having a 5.1 system I prefer to use my speakers to play. On the USB stick you have a jack socket and a manual reset button is detailed in 24 languages. I highly recommend it to people who want a good helmet at a great price ... I hope that my review will help you.
