Sony WM-EX 3.5 mm connector 4

Hmm ... you refer to an "old isa board from the computer." What is an "isa board"? What does it do in the computer?

And just out of curiosity: what brand and model of headphones are those that we see in the photograph, the headphones bracketing the Sony Walkman WM-EX80? Have you ever used headphones by Sennheiser or by Sony? How well do your headphones in the photo' perform compared to Sennheiser or Sony 'phones?

HI! audio-technica ATH-ES55 on the photo. top!! best portable headphones what I hear! yes WM-EX80. I have SE115 and for job (i'm a dj) HD 25-C II. Headphones Sony never used, only walkman's. For home listening I use
SHURE SRH440 headphones . Took a photo isa board
