Hello, bought some Audio Technica ATH-WS55 headphones and after 2 months of use they have developed a rattling noise in the right speaker, kind of like a rattling hiss when the music goes quiet, kind of annoying really. So, I have been told by iHeadphones that because I am out of my 7 day cooling off period that I cannot get a refund but they should be able to replace or exchange them with another model or brand. I have spent £61.99 so that is my budget, the headphones need to be on/over ear and look good and be portable. I wanted to get the AKG K451 but they do not stock them so am looking at Panasonic RP-HTX7 in light candy blue colour as I have heard the black ones look a bit cheep. What are the views on these and are they worth the 5 star reviews?
