what headset is better?

is the $30 "ps3 brand" headset better or is there a cheaper one with the same quality(s)? i was readin on gamestop.com and there were mixed reactions about the ps3 headset some say great some say ok some say complete crap. so should i get that or a cheaper bluetooth one? btw im going for comforbility/battery/and if it blocks the sound from that ear(i dont want that)

thanks in advance
