CM-H355

The Sony CM-H355 was an evolution of the iconic Sony CMD-H333, affectionately known as the Mars Bar phone. Little is known about this updated variant. Like the H333, it was designed to operate on first-generation analogue TACS networks, such as Vodafone and Cellnet in the UK. It also featured a pop-up earpiece to "provide a comfortable distance between [a user's] ear and mouth". The phone offered four hours of standby time and 90 minutes of talk time. It had a green backlight on the display and keypad. Sony claimed the phone had a "slim and stylish design" and delivered “powerful reception from advanced aerial technology”.
