As always, the problem is all those old earphones, headphones, and so on. The only chance of such thing prospering is if all those main cellphones come with earphones using such connection.<p>In computers, on the other hand, I&#x27;d love to have a phone with USB connector instead of the 3.5mm. That way I could get rid of those noise (caused by motherboard consuming power in variables ways), without using my USB-soundboard.
