The very popular YouTube video reviewer TX Brad has reviewed the CoolStream Bluetooth Stereo Headphones. He feels the headphones are lightweight, coming in at a mere 2.5 ounces with a comfortable no-slip rubber liner on the inside of a stylish glossy exterior along with nicely made leather ear pads. The rechargeable battery makes for over 5 hours of music streaming depending on what volume level you choose to listen to your music. The multi-function button will control your pairing as well as stopping your music to take a call with the integrated microphone. After your call simply press the multi-function button again and your music will return right where you left off.
