I have feeling that the sound control on that earbud will deteritate quickly. Why do i say that? Because i happen to have bought a pair of earbuds very long ago...that happens to have the same exact volume control. but in different color plastic, mine is blue. The volume control sure are the same, but im not so sure about the earbuds that conects to the control.
I bought it in chinatown, in one of those giftshop stores that have almost everything thats made in china. toys, dishes, kites, boomboxes, walkman speakers.....etc.
The pair i own also came with that 1/8" plug. so i have a feeling that this indeed is the same pair i have just with the aiwa name on it ...and a different plastic casing for the earbud drivers.
i cant strongly comment on the sound quality. But the earbuds sure sounded like something coming from '80s technology...hehehhe, they sounded thin, not much bass.
I did like the mono to stereo switch, but it gone bad after awhile and stopped working.
For the sound quality i think this will only worth 5-6$.
the piece i have now, its all tangled up, and the wires almost disconnected.
