I have been using X-mini Max ( 2 speaker ) for over 1.5yrs now . Bought off ebay long time back .
Karan as far as there bass is concerned , after opening the speakers the vacuum tube expands and provides lil bass note's present in the song . Thats enjoyable @ times . But a lil sad part is that when we expand the speakers and bass comes in , then the speakers tend to vibrate and start moving

( yeah actually on high volumes ) . So u might risk them falling down from a high table . to avoid this , i keep them on a spare mouse pad which absorbs the vibartion and keeps the speaker glued at one place .
Overall , even when un-expanded , these speakers sound great simply out of the box . Vocals are amazing , bollywood tracks sound great . Even club house mixes , jazz etc sound amazing . They are actually very loud for there size , and most important they dont loose there clarity even at high volumes . There portability is amazing , i use them while i have my shower , and at nights while sleeping . There battery life is amazing , easily chargeable via USB , once fully charged last for some over 14-15 hours . I put them on before i go to sleep , and till morning they are just playing

( I take a sound sleep of min 7-8 hours , so imagine battery life to be great ) .
Its a must buy . Very much recommended by me . Do go for it .
P.S - I guess i bought the mini max for some 1900 bucks , but then that's 1.5yrs back ( and yeah i am talking about the original's )
U 'll even get a soft cloth pouch to carry these speakers , and that's a good useful accessory
