DJ44S700 4.4mm Ground Pin Adapter -- Exclusively for SONY NW-ZX706 and NW-ZX707
All-in-one design with exclusivity
The DJ44S700 is designed exclusively for SONY NW-ZX706 and NW-ZX707 music players. It cleverly hides the gold bottom cover under the black top cover, while its exterior matches the classic design language of SONY music player. The CNC-molded metal shell not only increases the grounding area, but also effectively enhances the shielding effect.
Why is Sony's 4.4 mm jack not connected to the ground?
The conventional balanced headphones cable has only four connection points, namely R+, R-, L+ and L-. However, it does not feature the use of the Ground point on the 4.4 mm plug.
On the other hand, if the 4.4mm headphones jack was grounded, there might be impacting feedback when plugging and unplugging. Perhaps, for this reason, the Sony player's 4.4mm jack is not connected to the ground.
Why does the sound quality improve after being grounded?
When using a properly grounded 4.4mm headphones cable with shielding layer, sound quality can be significantly improved, especially when paired with metal-clad devices such as the SONY NW-ZX706 and NW-ZX707.
This is because the metal-clad music player forms an effective shielding system when connected to the shielded 4.4mm headphones cable, reducing the effects of electromagnetic interference. This design optimizes the purity of signal transmission, resulting in a more immersive and detailed listening experience.
Specially designed ground pin
The chassis of the Sony players are connected to the ground of the 3.5 mm jack. The ground pin of the DJ44S700 is designed much shorter than the standard 3.5mm headphones plug, which not only ensures normal grounding, but also brings great advantages.
First, it protects the device from the influence of external electrostatic or electromagnetic induction. Secondly, it extends the life of the socket by reducing the wear and tear that can be caused by frequent plugging and unplugging. In particular, this unique design prevents damage to the jack due to unbalanced force, which means the pressure point can be overly biased toward one side when inserting or pulling the adapter at an inclined angle. Since the 3.5 mm headphone jack uses a plastic chassis, this is very likely to damage the jack.
