Do bluetooth headphones with a aux port work without power?

Answer 1

Favourite answer

Some bluetooth headphones can also work by plugging them into an amplifier. The amplifier provides the power that drives the sound producing elements inside the headphone. Since bluetooth has limited bandwidth, audio quality is not that good even if you have the best bluetooth headphones. Get wireless headphones instead.  They will work with practically any audio equipment that have a line level audio input, either RCA jacks or headphone jack or miniplug jacks.

Answer 2

Scopes help. A colonoscopy is a procedure to examine the inside of your colon (intestine) with a scope. A scope is a flexible tube with a small light and camera on the end. Look for the answer there.

Answer 3

Since Bluetooth is supposed to work without wires, one can assume that you are referring to the port used to CHARGE the headphones between usages.
