Walkman E Series

E Series devices have been marketed since 2000, although in its current form since 2008 as entry-level, candybar styled players.

The player looked like a cigarette lighter and was deemed "ultra compact and light", weighing 45 grams.

[10] Shortly afterwards the NW-E500 and NW-E400 series were introduced, also marketed as the Walkman Core,[11] with capacities ranging from 256 MB to 1 GB.

[13] These feature a multifunctional knob controller (the trademarked "Jog Dial"[14]) used for navigating similar to some of the earlier E Series and MiniDisc Walkman.

The NW-E300/E200 series, nicknamed and also marketed as the Walkman Bean, was released in October 2005, and production ceased in April 2006.

It was also available in four colours, named after jellybean flavours - Tropical Ice (blue), Cotton Candy (pink), Licorice (black) and Coconut (white).

[25] Supported multiple codec ATRAC (ATRAC3 66 kbit/s, 105 kbit/s, 132 kbit/s, ATRAC3plus 48 kbit/s, 64 kbit/s, 256 kbit/s) MP3 and WMA (and later AAC), via SonicStage 3.4 software for music management and transfers of tracks.

This series also worked with Linux and Mac using the free software originally called NW-E00X MP3 File Manager, that eventually become in Symphonic, and now JSymphonic.

In March 2007, Asia, Australia, New Zealand, some countries of Europe and Canada had the Walkman NW-E010 series (NW-E013, NW-E015 and NW-E016) a small USB flash player.

Weighing only 23 g, the NW-E010 was available in capacities from 1 to 4 GB and came in five colors: pink, violet, teal, black, and gold.

Its features included a rechargeable lithium-ion battery, built-in FM tuner, a three-line color OLED display, calendar and time function, and Clear Stereo and Clear Bass technologies to enhance the audio quality.

It had a five-band equalizer and Sony's "clear stereo" which means pre-set EQ function.

Sony mentioned the capability of FM reception, (Japan band of 76 to 90 MHz), usually devices with an F at the end of the model number.

[31] This player was the first featuring Karaoke Mode, a new function that reduces lead vocals in a song.

[32][33] A smaller sized, low cost E Series player without video capability, the E050, was released in Japan in 2010 and in 2011 in Singapore,[34] Mexico and Eastern Europe.

The E470 was introduced in 2012[37] and for the first time featured games - it comes preloaded with Puyo Pop Fever and Number Place (sudoku).
