Query: Beware 90 day limited warranty

Warranty is only for 90 days. Mine lasted 16 months and then one side stopped working. Sony will charge you more to reapir them than the cost to buy again. So if you want a set of headphones for 90 days them go ahead and purchase these. Sennheiser has a two year warranty. These headphones only have a 90 day limited warranty. Just hope you don't get a bad set.
