I sometimes listen to audio when I sleep.
Main Question: What's a bluetooth headset product that will not make noises/vibrate when low battery? No noise, including the device telling you "battery very low" with a voice, and also no beeping, no vibrating notification when battery low
Budget: Less than 100$
Form factor of bluetooth headset: Preferably something like this https://www.amazon.com/LG-Electronics-HBS-750-Bluetooth-Wireless/dp/B00FO0IHMY/ref=sr_1_2?ie=UTF8&qid=1485926696&sr=8-2&keywords=bluetooth+headset+lg
Since it would stay on you even when you sleep
Why a simple search did not work for answering my question: Specifications for bluetooth headset products do not state whether or not there is a "battery very low" sound or vibration when the battery is low.
Other Specifications: If it does not make beeping sounds when you adjust the volume with its buttons, that would be good too obviously because the application is for sleeping.
