A:AnswerA lawn mower is a lot but I think it would. I was at the grocery store yesterday, and could only hear sound via the headphones. The stupid "Alexa" checkout bot was talking when checking out so I could faintly hear that. But I had the volume down low. If you wanted to up the volume, I think it would be fine.
A:AnswerThanks for your inquiry. Our JBL Tune 670NC can connect to any Bluetooth-enabled device, including Smart TVs. However, since these headphones don't have a low-latency codec, you may encounter audio-video delays when connecting with your TV device. Alternatively, if your TV has an Aux input, you can also use an Aux cable for a wired connection.
A:AnswerOf course you have to charge headphones :) Simply plug them in using the USB charger they gave you or another one you probably have laying around. It uses the latest plug that the iPhone switched over to.
