How to fix the volume wheel and buttons (Cloud ii Wireless)?

Currently my headset’s volume wheel still spins but does not register volume adjustments correctly: trying to turn volume down makes volume fluctuate and rise slowly instead and turning volume up is not a smooth action (not the hardware, but software). My headset’s power button is very “creaky” and does not feel like it will last. The former is not a serious issue since I have media keys but disappointing nonetheless and the later concern is something I feel will break down the road making the headset useless.
