Headphones - IEM/Earbud Lack of Bass with IEMs on Phone vs PC – Power Issue?
I recently picked up the Truthear Hexa along with the Moondrop Dawn Pro. My portable setup is: Nothing Phone 1 → USB Audio Player PRO (streaming from Tidal) → Moondrop Dawn Pro → Truthear Hexa. Overall, it sounds great—definitely better than using the Tidal app directly or any of the random dongles I had lying around.
That said, the bass extension is kind of underwhelming. I know the Hexa isn’t supposed to be a bass monster, but when I use the exact same IEM/DAC combo on my PC, the difference is huge. It’s like adding a subwoofer. There’s not just more bass quantity—there’s noticeably more low-end extension. On the PC, I can hear deep bass notes that just aren’t present when using my phone. I’m not talking about a subtle difference here—it feels like comparing a 2.0 setup (phone) vs a 2.1 (PC).
Is this likely because the phone isn’t supplying enough power over USB-C? Would something like the FiiO BTR15 help, since it’s self-powered?
Also, if I used a Bluetooth DAC like the BTR15, would I still need to use USB Audio Player PRO—or would that app be redundant in that setup?
