Congratulations!Youarenowtheproudownerofapairof
headphonesresultingfrommanyyearsofR&Dledbyateamof
passionateaudioandacousticsengineers,materialscientists,
chemicaltechnologistsandaudiophiles.

TheOPPOPM‐1utilizesaplanarmagneticdriverthatsetsitapart
fromthemajorityofheadphonesonthemarket.Inourplanar
magneticheadphone,soundisgeneratedbyaverythinandlight
diaphragmwhoseentiresurfaceareaisevenlydriven.The
diaphragmisdriveninasymmetricpull‐pushmanner,andthe
magneticsystemandconductorpatternshavebeenoptimizedfor
maximumsensitivityandconsistency.Thisallowsthediaphragmto
generateverystableandlinearpiston‐likevibrations,ensuring
phasecoherenceandhighresolutionperformancewithminimal
distortion.




UniquetotheOPPOPM‐1istheuseofadouble‐sideddiaphragm,
whichallowsustoplacetwiceasmanyconductorswithinthe
magneticfieldandeliminateanypassivereturnzoneswherethe
conductorsdonotwork.Thisresultsintheuseof100%ofour
conductorlength,whichinturnresultsingreaterefficiency.In
addition,ourflatconductorpatterneliminatesinductance‐related
intermodulationdistortion,commonwithdynamicheadphones,
andtheOPPOPM‐1’spurelyresistiveimpedancemeansthatsound
qualityisunaffectedbyaheadphoneamplifier’soutputimpedance.

TheOPPOPM‐1combineshighsensitivitywithlowweight,allowing
ittobeusedfreelywithportabledeviceswithoutrequiring
additionalamplification.Itscircumaural,openbackdesignprovides
thebestinsoundqualityandcomfort,andtheoverallrugged
constructionensuresthattheheadphonescanwithstand
mechanicalandenvironmentalstress.

TheseaspectsoftheOPPOPM‐1’sdesigncombinetoprovidea
transparent,highlydynamicsoundthatexhibitswell‐balancedtonal
qualitieswithverylittledistortion,resultinginalistening
experiencethatisbothfreeoffatigueandcapableof
communicatingeverynuanceofyourfavoritemusic.

Weareproudoftheworkwehavedonewiththeseheadphones,
andwehopetheybringyouyearsofenjoyment.
