The lengths that Oyaide as a company go to cannot be under estimated. Sound quality is their primary goal along with meticulous attention to detail in design and manufacturing. 

The basic material for the P004e European Schuko connector is Beryllium Copper, which provides maximum conductivity, strength, and a secure contact.

The surface of the P004e Schuko is thoroughly polished TWICE. Then, a layer of platinum (0.5 micron) is plated directly onto this polished surface, and the polishing process is again applied twice. Next, the P004e receives the final Palladium plating (0.3 micron), and is again polished twice. The combination of these polishing processes, platings, and thicknesses of platings ultimately leads to the final sound character. This connector is Oyaide’s best male Schuko connector, with the exception of the M1e

For the body Oyaide has chosen high density PBT, mixed with 30% glass filler. This combination was used to maximize rigidity, thermal stability and provide high resonance absorption. The outer shell is Polycarbonate.


■ Contacts
As well as the Premium Series, M1/F1, we employed beryllium copper for its superior conductivity and excellent mechanical characteristic.
The contacts of P-004/C-004 are heat treated to insure electromechanical integrity. The 1.0mm thick and 6.0mm wide contacts provide maximum contact area, have more than 8kg of holding power and reduce vibrations at the point of contact with no loss of signal transmission.

■ Plating
The manufacturing process is started from foundation coating. The material which was punched out as a part is polished by hand piece by piece after machined barrel-polishing.
The plating of the P-004/C-004 is a combination of platinum and palladium which were selected as a result of repeated listening tests. The inner platinum layer is 0.5 microns thick and the outer palladium layer is 0.3 microns thick.


■ GF+PBT body
30% glass filled PBT has excellent machine-ability and provides superior electrical isolation. The highly rigid body of the P-004/C-004 effectively attenuates high-speed vibrations. All screws, which were originally designed for P/C series, are made of highly rigid stainless steel which is non-magnetic substance. Moreover, the cable cannot be separated from the plug by a force less than 30kg, a significant safety feature.

■ Outer Cover
The outer cover of P/C series is made of PC (PolyCarbonate) for its rigidity and hardness. It helps to attenuate tiny vibrations in quick response and reduce distortions by its superior mechanical strength.

1 review for OYAIDE P004E SCHUKO PLUG

  1. Rated 5 out of 5

    Rene Christensen (verified owner)

    Only rated below Oyaide M1/F1, this plug Oyaide P-004e shares the same contacts (pd>Pt>/BeCu)

    After several listening test, where I combinated the P-004e plug with C-037, C-046, C-079 IEC plugs, I have come to, that the P-004e schuko plug ONLY sounds at it´s best together with the C-004 IEC plug.

    Another aspect is that the combination P-004e / C-004, AT LEAST NEEDS a 3 x 2,5 mm cable with a very high, pure copper content, to shine.

    Best regards
