I've just bought a new NW-A35 MP# player, but cannot connect my Plantronics Backbeat Fit bluetooth headphones. It doesn't detect them, despite having them in pairing mode. I've used these headphones with my Ipod Nano and Iphone with no issues. Any ideas?
Make sure not to cover the built-in Bluetooth antenna (11) of the unit especially a metal object. The antenna allows the Walkman to connect with Bluetooth devices. Place the Walkman and the Bluetooth device as close together as possible to secure the connection.
You may also try to connect different Bluetooth headphones to isolate the issue.
