With downturn driving in all the major sectors; technology world hardly seems to be affected as the endless headphones; earphones spree continues to make an indelible mark in the minds of the consumers.

Keeping the pot boiling this time around is Audio Technica, who has rolled out a new series of 4 headphones (named as ATH-EQ300G, ATH-C100G, ATH-C500G and ATH-CK300G) uniquely, designed for PSP and DS/DSi.

The plus point is that all the four headphones permit you to control the volume from the headphones themselves rather than giving you a pain to use hardware or software controls. No word on the pricing front yet; though they are expected to be made available this April in Japan.
