Thanks for looking. No, there are no details in the manual about a volume limiter. The Hi/Low gain is an electronic switch, but doesn't impact the overall volume.
No, the only thing on the DAP is low and hi gain, neither of which make any difference to the overall volume. It may be that the impedance on the buds is too high to drive very loud.
Hi. I've just bought some Sony WF-C500 earbuds, and paired them with my Hidizs DAP. Nice sound, but not enough volume even when they're maxed out.
I'm listening via Bluetooth. Any ideas how to increase the output?
Thank you.
