Nexus 5X internal speaker is worse than Nexus5!

I hear distortion sound from default ringtone since I received N5X. Its totally different sound from listening by Headphone. I remember that N5 was not like this. even N5 has terrible speaker.
do I need to contact google and exchange to new one??

New Moto 360 (1st Gen). Battery less than 3 hours in Airplane Mode

Got the Moto 360 as a deal with my Nexus 6 4 days ago but my experience has been nothing short of horrible with the 360. I have tried everything i could find on the internet, tried different Android Wear version, Factory Rest, deleting apps on phones, fresh sync after factory reset etc etc.

As a last resort I placed the 360 in Airplane mode but still the 360 discharges battery continuously within 3 or 4 hours at most.

I don't have any apps installed, just stock with everything turned off but this is still happening.

Is this a defective unit?
Somebody said that it gets better gradually over time but this is just ridiculous. Any help will be appreciated.

regards

set Android 6.0 default USB config to MTP rather than “charging only”?

Whenever my device (Nexus 5, Android 6.0) connects via USB, the USB config always defaults to "charging only".
This is a big problem since whenever I'd like to listen mp3 connecting nexus 5 to my car stereo I have to manually set the mode to MTP.
The big annoyance is that whenever I turn off the car engine and then restart it the nexus 5 USB connection go back to "charging only" !!!
I already tried debugging mode:
Develop settings -> USB Configuration is set to MTP.

Any chance to set USB default as MTP?

Thanks
