Can the boxes only recommend, will not say much about it. The Akkalaufzeit of 12 hours is not an exaggeration, but comes naturally always depends on the type of use. The sound I find super, problems getting the device only at full volume in rock songs with a lot of drums and guitar. All other genres from jazz to hip-hop sound even at high volume class. The bass is well regulated, not too intense but also not too little available. Anyone interested can change the bass on the equalizer on Smartphone (works great with the "Pro Player"). Practically, the way also that you can connect the Jbl batch via cable or via Bluetooth at the same time and thus, for example, while gambling at the Ps3 can we know, no background processes allowed on the phone listening to music. Best Regards :)
