If the cable on your new device feels different from your previous one, this may be normal. Slight variations in cable length between units are part of the factory default settings.
In addition, the cable may stretch slightly over time with regular use, which is also normal.
You can manually adjust the cable as shown in this video: VOLTRA I - Manually Adjust Your Cable - VOLTRA I Tutorial
If the cable still feels too long after adjustment, you may carefully trim the excess with scissors.
