WM-EX655
The WM-EX655 is a playback-only Walkman with an automatic reversal function. It features Dolby B, remote control operation, and bass boost, and is compatible with AA batteries and gum-type rechargeable batteries. It is an early high-end model that enhances convenience through the introduction of electronic control functions.
The WM-EX655 combined a durable aluminum shell with shock-absorbing Express material that raised impact resistance by nearly threefold, giving the player a tougher build than most basic models of its period.
It was also the first entry-level unit to include a remote with an LCD, which made everyday control easier without pushing the model into a higher price tier. The WM-EX655 brought durability and remote-based control into the entry-level Walkman range, extending features once reserved for higher-end models.
