SPILL | Fully upgrade the Acoustune HS1700 mid-range headphones from the inside out, and replace them with new units and new casings

Follow the signature module design

In addition to the Myrinx dynamic unit, another signature selling point of Acoustune is the module design. Like the previous HS series, the cavity and skeleton of the earphones are made of different metal materials to reduce the noise between acoustic and mechanical components. Mutual interference and distortion. Drawing on the development experience of the Acoustune ST1000 CM upgrade plan and the HS2000MX, the HS1700 series earphones are replaced with a new shell, with more rounded corners, which are indeed more comfortable to wear than previous models. The cavity of the HS1790TI this time is made of titanium alloy and then processed by CNC. It has stronger rigidity than aluminum or stainless steel, thereby improving the resonance suppression and the response of the unit. As for the cavity of the HS1750CU, the original brass is then made by CNC. After the bright black surface treatment, in addition to increasing the beauty, it also makes the brass not easy to oxidize and discolor. The skeletons of the two are also made of anodized aluminum, which is processed by CNC, providing excellent and stable support for the cavity and socket.

In terms of terminals, both earphones maintain the long-established Pentaconn Ear plug, which provides excellent conduction performance and robustness. With the ARC51 eight-pair headphone cable, it is made of a mixed core of silver-plated OFC cable and ultra-fine OFC cable, and is braided in a twisted pair and three-shielded way.
