I bought a ProCIV bluetooth sleeping mask on Amazon (2019 updated version) but it’s barely audible at full volume. In the past, I used 3.5mm corded sleeping masks which are plenty loud but the cord breaks eventually.
So begins a quest to rebuild the mask. With some helpful advice from forum staff, the headphones were fixed and received some upgrades, including a larger LiPo rechargeable battery from Adafruit.
One of the things I love about Adafruit, if you guys say something will do X then it does X. Your electrical engineering skills are inspiring and advertising integrity matters. That’s why whenever I have a small electronics project I usually look to see if Adafruit has it first. You guys are awesome.
And the result:
I feel completely justified with how much I spent on components to create what I have now. It’s wireless, loud, 30+ hour battery life, can sleep with it on. Done with commercial headphones and sleeping masks. This is good enough to serve both roles for my needs. Well except music production I do have another pair of headphones for that. I want to make it smaller but I don’t want to give up the 30+ hours of battery life lol. A good problem to have. 🙂
See some build pictures below and the full project runthrough on the Adafruit Support Forums thread here.
Well done!
