I be a Sony fan but I buy ht-p50 because of it be a new product with great speaker design from Samsung . I like Samsung 's cell phone a lot so I give a chance and buy this from B&H; Photo Video store -lrb- www.bhphotovideo.com -rrb- in NY via online . I like the overall of the product such as sound output and again nice speaker design . but after two week later , when I turn it on from sleep-mode , I hear a loud noise from the back of the unit . I find out the noise be from cool fan -lrb- just like a pc but smaller size -rrb- . the noise be just like a old pc fan before it go bad . so I tap it lightly and the noise go away for a few seconds and then noise come back again . so I tap it again . this time the noise go away . remember , this unit be only two week old ! I never have bad experience with all of my Sony or Canon equipment . Poor quality control from Samsung ! I will never buy Samsung product again . do not have time to take it to authorized service dealer since I do not have time for this -lrb- put all into the box then drive 12 mile to the service center and leave it for several week ? -rrb- . no way ! I buy this to enjoy , not to spend money and then time to fix it . I will not buy Samsung again ! ever !
