I use these speakers for 1 year and I'm still amazed. Performance is impressive for the size. Both an ipod for a stage piano type keyboard Yamaha and even a guitar amplifier booster! Nice balance of sound: bass, treble made very satisfactory. Does not saturate.
Good value for money. It's worth it. We can make use versatile because there are separate channels for input and Ipod input jack.
Too bad we can not play (with) while you listen to a song.
