WM-WE7

The WM-WE7 advanced Sony's cordless cassette concept by integrating the entire wireless system into a pair of foldable overhead headphones. Instead of relying on a clip-on receiver, the headset handled signal reception and basic remote functions, leaving the cassette unit to focus solely on transport duties.

The result was a simpler and more unified layout than earlier attempts in the series, turning cordless playback into a single wearable system long before true wireless audio became standard.

The cassette unit carried the expected features for its class.
