the px 100 headphone have great sound almost unreal for the money . this be the 4th set I have purchase and recommend they 100 % . one thing to take into consideration be that these headphone be not extremely durable . I would not recommend these for kid or any `` rough '' use . frankly they be not mean for that hence the reason I do not deduct for durability . also if rough up the foam speaker cover can come off fairly easily . you & I will simply put they back on ; kid may not and loose they . by the time you find replacement foam cover it could be less aggravate to purchase new headphone . sennheiser do provide a well design case to protect the headphone while not in use . also , note that other user report a faulty wire connection . I have run into something similar on one only one of my headphine set and that be the set my daughter be use . I chalk that up to abuse since none of the set I have use have this issue . still , consider the amount of people that have report this issue , I would keep it in mind . bottom line : people who will take care of the headphone and want a budget set with excellent quality = yes rough use -lrb- ie : kid on school bus -rrb- = no
