Several years in a row I have Sony Ear Headphones bought in the lower price segment, Mostly because of the good sound and rich bass. The durability (with good handling) was a criterion that spoke for choosing these headphones. Unfortunately EX15LP no longer come to the life of their predecessors ran: after ~ 5 months was the right headphones slowly quieter until it was no longer make a sound after about 3-4 days. Two times I have exchanged this product and each time the same defect was right in (almost exactly) the same period.
Technically sound they are playing in the same league as their predecessors - giving a total for 2 stars enough. Because three times the same defect in the same period leads me to believe crude product or production errors. Interestingly (but Bewertungsunabhaengig) I found the comment of the dealer who insisted on a cable break and in his view, the Exchange had agreed only out of goodwill because quote: "... Sony on Kabelbrueche neither warranty nor gives guarantee claims!".
