Mr. Spence, 

you've obviously heard the complaints so let’s work on fixing this.

send out a 40% off discount like you have in the past, fix the volume slider, up the Rakuten cash back program, increase upgrade discounts from 15 to 30 across devices. 
 

offering sonos ace at a significant discount to loyal customers will roll out sonos branding into the public. Marketing needs to improve significantly. This is the easiest product to market, yet I never see it done with newer marketing ideas. 

Hire influencers, put out positive app content, explain why there was a change to begin with. 
 

fix the volume slider 

I’ll buy the headphones. I’ll give you some time. just get at it and fix this….fast.

oh, and fix the volume slider
