Stock firmware utilizes highly restrictive CPU governors (likely a custom variation of powersave or ondemand) that scale frequency based strictly on audio processing needs. CFW often utilizes generic Android kernels or modified init scripts that may default to performance or interactive governors.
Sony has moved on to the NW-ZX707 and the A306. They are unlikely to release another firmware update for the A105. This means the community now owns the software roadmap.
Developers are currently working on Android 13 Go Edition ports for the A105, which would reduce RAM usage by 40% compared to stock Android 9.
Furthermore, a leaked beta of "Project Kyro" claims to add LDAC Dual Mode (sending LDAC to two headphones simultaneously)—a feature Sony reserves for $1,500 players.
As long as the hardware remains capable (the Snapdragon 430 is fine for audio), the custom firmware scene will stay white-hot.
The latest hotfix (released last week) enables hardware DSD remastering for all playback—even Spotify and Apple Lossless. The modder found a hidden API in the CXD3782GF DAC chip. Toggling this on adds a holographic width to your headphones. It’s controversial (purists say it’s EQ gimmickry), but for rock and electronic, it’s addictive.
| Aspect | Stock A105 | Custom Firmware (Hot Build) | |--------|------------|-----------------------------| | Sound quality | 7.5/10 | 9/10 | | Battery life | 5/10 | 8/10 | | UI speed | 5/10 | 8/10 | | Stability | 9/10 | 7/10 (rare crashes) | | Value | 6/10 | 9.5/10 (transforms the device) |
Bottom line: The Sony NW-A105 with custom “hot” firmware is a mini WM1Z for under $200 used. If you already own one, the mod is free and absolutely worth it. If you’re buying new – consider the A306 instead (better stock battery), but still mod it.
Recommendation: Try MrWalkman’s DMP-WM1A mod v2.5 first – it’s the most stable “hot” build as of 2025. Avoid experimental “extreme bass” variants unless you love distortion.
