Open Alpha Headphones Bass Adjustable Ear Cups 2.5-3.5mm Jack

thingiverse

This is a revised version of Balazar's Open Alpha with bass ports. It has been upgraded to include a robust and modified output jack, allowing for the use of 2.5 and 3.5mm connectors instead of the standard Hirose connector. The Hirose connectors are often difficult to find, while the 2.5mm connector is easy to locate and offers greater versatility. The connector wall has been thickened by 0.2mm, and the output hole diameter measures 5.9mm, perfectly accommodating the Lumberg 3.5mm connector. This specific connector can be found at http://au.element14.com/lumberg/klb-4/connector-rca-jack-3-5mm-3way/dp/1200144?ost=1200144&selectedCategoryId=&categoryNameResp=All&searchView=table&iscrfnonsku=false.
