First of all I would encourage anyone looking at buying anything from JB Hi Fi to look at their reviews first...I would be very surprised if anyone bought anything from JB Hi Fi after reading the reviews! Unfortunately I did not read the reviews and I purchased a pair of Sony XM5 headphones from JB Hi Fi because my Sony XM3's were getting a bit old. My XM5's were fine to start with, but defects started occurring not long after purchase. When I returned them to JB Hi Fi at Warriewood Square, under warranty, I was concerned straight away when the young girl behind the counter tried to make out that there was no issues with the item? Am I a complete idiot? Why would I go to the trouble of returning for repair if there was no issues with the item? When I insisted that the item be repaired I received an email 2 weeks later explaining that my job had been accepted, but that no errors were found with the headset?! So now I'm stuck with some new $500 headphones that I will probably never use again. My advice, stay away from Sony and stay far far away from JB Hi Fi.
