4.4mm Erdungspin-Adapter
Ermöglicht die Verwendung von 4,4-mm-Kopfhörern am MOJO Versteckte untere Abdeckung mit schraubenlosem Design Zentriertes, gerades Steckerlayout
Ermöglicht die Verwendung von 4,4-mm-Kopfhörern am MOJO Da MOJO nur mit zwei 3,5-mm-Kopfhörerbuchsen ausgestattet ist, ist ein Adapter erforderlich, wenn Sie 4,4-mm-Kopfhörer verwenden möchten. Der DJ44MOJO ist ein speziell für MOJO entwickelter Adapter, der die beiden 3,5-mm-Buchsen in eine 4,4-mm-Buchse umwandelt. Sein äußeres Design entspricht der klassischen Designsprache von MOJO, was für ein sehr passendes Erscheinungsbild sorgt. Verdeckte untere Abdeckung mit schraubenlosem Design Die gut durchdachte, versteckte Bodenabdeckung mit einer einzigartigen schraubenlosen Struktur ist nicht nur ästhetisch ansprechend, sondern verbessert auch die Haltbarkeit des Geräts. In Anbetracht der Notwendigkeit des häufigen Ein- und Aussteckens von Adaptern verwendet der DJ44MOJO ein robustes Gehäuse aus einer CNC-gefertigten Aluminiumlegierung, um die Stabilität der Steckverbindung zu gewährleisten. Durch die Verdickung des Gehäuses und die Vergrößerung des Erdungsbereichs wird die Abschirmwirkung gegen Störungen deutlich verbessert. Zentriertes, gerades Steckerlayout Die Stecker haben ein gerades Design, dessen Höhe mit der der 4,4-mm-Kopfhörerbuchse vergleichbar ist, was die Ästhetik des Gebrauchs verbessert. Für den internen Anschlussdraht wird das typische ddHiFi-OCC-Kabel verwendet, das mit silberhaltigem Lot verlötet ist, um eine verlustfreie Übertragung des Audiosignals zu gewährleisten. Mit viel Liebe zum Detail ist der Stecker fast bündig mit dem Gehäuse, was zu einer Inkompatibilität mit der Schutzhülle des Produkts führen kann.Exklusiv für

4.4mm Erdungspin-Adapter All-in-One-Design mit Exklusivität Verbesserte Klangqualität Speziell entwickelter Erdungspin Der DJ44S700 wurde exklusiv für die SONY NW-ZX706 und NW-ZX707 Musikplayer entwickelt. Er versteckt die goldene untere Abdeckung geschickt unter der schwarzen oberen Abdeckung und passt damit zur klassischen Designsprache der SONY-Musikplayer. Die CNC-geformte Metallschale vergrößert nicht nur die Erdungsfläche, sondern verbessert auch effektiv die Abschirmwirkung. Verbesserte Klangqualität Die Verwendung eines ordnungsgemäß geerdeten 4,4-mm-Kopfhörerkabels mit einer Abschirmungsschicht verbessert die Klangqualität erheblich, insbesondere bei Geräten mit Metallgehäuse wie dem SONY NW-ZX706 und NW-ZX707. Dies ist auf das effektive Abschirmungssystem zurückzuführen, das durch den metallummantelten Musikplayer und das abgeschirmte 4,4-mm-Kopfhörerkabel gebildet wird und elektromagnetische Störungen reduziert. Dieses Design optimiert die Reinheit der Signalübertragung und sorgt für ein intensiveres und detaillierteres Hörerlebnis. Speziell entwickelter Erdungspin Der TC35M2 ist mit beliebten verlustfreien Musik-Apps wie Apple Music, QQ Music, Netease Cloud Music und Sony Lossless Music kompatibel. Während die meisten verlustfreien Musikformate, die von diesen Apps angeboten werden, 44,1kHz, 96kHz oder 192kHz sind, unterstützt das TC35M2 PCM-Dekodierung bis zu 384kHz. Ausgestattet mit einem unabhängigen Dekodier- und OP-AMP-Chip liefert der TC35M2 eine stabile Leistung und Ausgangsleistung, so dass er für die meisten 3,5-mm-Kopfhörer auf dem Markt geeignet ist.Exklusiv für

In addition to DACs and headphones, the manufacturer primarily offers a wide range of different adapters. ddHiFi has set itself the goal of focusing on a concise and short design language, producing user-friendly accessory products and focusing on product material and craftsmanship details, while always keeping costs under control.The highlights of the ddHiFi TC100-COA at a glance:- Supports 24 bit / 192 kHz- Strand is made of pure OCC copper- Constant impedance of 75 Ω- High quality digital audio transformer- Multiple lengths possibleFrom old to new in high qualityThe ddHiFi TC100-COA is a USB-C to digital coaxial converter. With this converter, high-quality but technically dusty systems can still be used sensibly. To ensure that no compromises have to be accepted here, particular emphasis was placed on high material quality and workmanship. The centre conductor of the coaxial cable is made of 99.9999 % pure OCC copper, and the thickness enables a constant impedance of 75 Ω - which is crucial for coaxial transmission.The inner workings play alongInternally, a DA101C audio transformer from Murata is at work, balancing the USB input and coaxial output circuits. This ensures a consistently high quality digital audio transmission. This puts a ddHiFi TC100-COA in a different technical dimension than inferior USB conversion devices that do not use such a chip.Flexibility without limitsBecause a USB-C port was chosen as the input, the use of a variety of different cables is possible. There are hardly any limits here, so connectors other than USB-C, USB-A or Lightning are also possible.
