The pinout of some Headsets delivered by Sony Ericsson are known to use a different pin layout. The layout of the HPB-20 is as following (unconfirmed, measuring the pins shows some strange interconections):

  • 1/Tip: Mic
  • 2: right speaker
  • 3: left speaker
  • 4/Base: ground

This pinout is not compatible to Neo. To use this headsets you have to rewire them which requires soldering or usage of a simple adater doing the transformation (however, i currently do not know of any existing).

The following sections describe the modifications made to a headset originally delivered with a P910i (HPB-20).

The modification can be made with the following steps (take care to have a quick but steady hand, the soldering on the image is quite dirty because i had to solder several times):

  • unsolder the white cable from the M+ solder contact
  • unsolder the two combined green cables from the LS solder contact
  • untwist the two green cables so they get separated
  • twist the white cable together with the green one from the small grey cable (coming from left speaker)
  • solder the white/green cable pair to the LS solder contact
  • solder the green cable from the big grey cable to the solder contact M+
  • test if everything works now, close the casing if and enjoy stereo sound :)

The pinout of some Headsets delivered by Sony Ericsson are known to use a different pin layout. The layout could is as following (unconfirmed, measuring the pins shows some strange interconections):

  • 1/Tip: Mic
  • 2: right speaker
  • 3: left speaker
  • 4/Base: ground

This pinout is not compatible to Neo. To use this headsets you have to rewire them which requires soldering or usage of a simple adater doing the transformation (however, i currently do not know of any existing).

The following sections describe the modifications made to a headset originally delivered with a P910i (there is a small number "Y536Z" inside the case, but i dont know if this is significant).

The modification can be made with the following steps (take care to have a quick but steady hand, the soldering on the image is quite dirty because i had to solder several times):

  • unsolder the white cable from the M+ solder contact
  • unsolder the two combined green cables from the LS solder contact
  • untwist the two green cables so they get separated
  • twist the white cable together with the green one from the small grey cable (coming from left speaker)
  • solder the white/green cable pair to the LS solder contact
  • solder the green cable from the big grey cable to the solder contact M+
  • test if everything works now, close the casing if and enjoy stereo sound :)
