Headphone Volume
Quiet headphones usually have one of three causes: the source file is quiet, a software limit is capping output, or the headphones need more power than your device provides. The third is a genuine hardware mismatch that no software fixes, and it is worth identifying early.
Find your cause
- Quiet on every device
- Points to the headphones themselves — likely a sensitivity or impedance mismatch, or physical damage.
- Quiet only on one device
- A software limit on that device. Start with headphones too quiet.
- Quiet only over Bluetooth
- Almost certainly absolute volume linking. See Bluetooth headphone volume booster.
- Quiet only on some files
- The source, not the hardware. Boost the file.
The two numbers that decide how loud headphones go
Sensitivity is how much sound pressure a driver produces from a given amount of power, and it is the more useful figure for predicting loudness. Impedance is electrical resistance: most consumer headphones sit at 16–32 ohms and run happily from a phone, while studio models at 250 or 600 ohms need far more voltage than a phone can deliver.
A mismatch here produces a distinctive result. The headphones are quiet at maximum on every device, the bass sounds weak rather than merely low, and no software setting improves matters. That combination points at power, and power is the one problem an amplifier solves and processing does not.
