Roland RH-D30 en RH-D20 headphones

Geschreven door Reind Dooyeweerd maandag, 30 juli 2007 02:49

Roland kennen we vooral (ik dan tenminste) van de digitale piano's, de drum computers en natuurlijk de legendarische TR909 waar zo'n beetje de house muziek mee uitgevonden is. Op het gebied van dj gear doet Roland eigenlijk niets maar nu komen ze toch met 2 headphones. Het lijken mij 2 OEM headphones maar waar ik ze nog meer van ken weet ik zo 1-2-3 niet. 2 nieuwe headphones dus van Roland die ook geschikt zouden moeten zijn voor dj gebruik.

De headphone komt er in 2 smaakjes, de RH-D20 (goedkoopste) en de RH-D30, qua uiterlijk verschillen ze vrijwel niets. Het verschil zal dus gemaakt moeten worden met de specs, van de RH-D20 staan ze online, van de RH-D30 echter niet en dus word het een beetje lastig vergelijken. De RH-D30 heeft echter wel grotere drivers dan de RH-D20 (45 ten opzichte van 40mm bij de RH-D20) en zal dus ook naar alle waarschijnlijkheid een hogere SPL max hebben.

The RH-D20 with 40 mm drivers contains CCAW voice coils for outstanding power and performance.
