Neck/Headache possible fm straps of the nasal cushion?

Well, this is a subjective question. I have been getting some neck aches (had already some problems on and off before) recently -- new on cpap for 1 month. I am using the Optilife nasal cushions. I sleep on both sides, and never on my back. The tube coming down may perhaps be restricting my chin position and freedom. I also feel mild soreness from the pressure of the head straps, but they are really not over tight.

Anybody has any recommendations which cushions might have the least of this problem? I am particularly sensitive to noise, and the quietness of Optilife I really like. Running at low pressures ~ 6.5.
