I got sick of the official Marshall app on Motif II so I wrote a faster unofficial one
The Marshall Bluetooth app on my Motif II A.N.C. is awful. Slow to open, laggy as hell, takes forever to talk to the buds. I got tired of waiting on a settings screen every time I wanted ANC or EQ, so I built a replacement.
Unofficial Marshall — small Android app, same job, not the official one. Not affiliated with Marshall.
What it does (tested on Motif II):
• Connects over BLE, actually feels instant
• Batteries (L / R / case)
• ANC / transparency / off + strength
• EQ presets
• Custom 5-band EQ (this one was a pain — official path is Classic SPP, not the BLE junk)
• Touch / wear / UI sounds
• A 2×2 home widget for battery + noise control
Other Marshall/Zound gear that uses the same BLE stuff might work. I’ve only lived on Motif II.
Install: you have to uninstall the official Marshall app first. Same Android package name, they can’t sit next to each other. That’s on purpose so pairing / Airoha identity still works.

arm64 Android. Unofficial, use at your own risk, case the buds if something weird happens.
If anyone tries it on Minor / Major / Monitor / whatever, tell me what broke.
