I bought a pair of expensive Sony Bluetooth headphones from amazon. They shipped a pair that was refurbished, as in they had a crack and then had been glued together. Sent it back as for a replacement. A few months later that pair cracked in the exact same spot- and they were out of warranty at that time :/ Before buying I did not come across any reviews mentioning that issue. When mine cracked I did another search for reviews and came a ton of individuals on different forums complaining about the same problem, but did not find any reviews on Amazon mentioning that- by then- know issue. Bought directly from amazon...
