And they're out of warranty (typical sony 1yr), well, seems i will have to evaluate what new offers does sony present at the IFA 2015, there's rumored xperia Z5 smartphone, walkman A20 and ZX100, but nothing has been rumored on XBA line of heaphones until now
They are the nest "earbuds" i have evr heard, coming from always sony buds and even the XBA-1, this one is boy the best thing. if nothing is offered at IFA, then i will go either for a XBA-Z5(amazon) or XBA-A3 (via accessoryJack) as they say A3 closely resembles z5 in tonal quality, but Z5 is all metal casing
so it doesn't discolors (tough my XBA-H3 never discolored at all kudos to sony on this)
