I got a new laptop recently and even with the audio at max, the volume was low. These headphones were reasonably priced after factoring points, so decided to give them a try. First things first, if you are looking to use the Bluetooth, take the time to CHARGE the headphones first. I was in such a rush, that I wasn't thinking, let alone taking a moment to read the directions. Pairing is easy and I have used them with my laptop and Samsung Note 4 successfully. In the past I avoided headphones due to the weight, however, I can wear these for hours and they do not hurt. As another reviewer mentioned for music or movies they are fine, however while you CAN use these to speak on the phone, the mic is poor, so I wouldn't recommend it.
This pair of headphones has a decent fit but if you wear them too long they can get uncomfortable...one big gripe with this set is that the on/off or the volume button will inadvertently make a call on my iphone...not good when using them at 2am and it calls the most recent number on your phone....this seems to be a big bug!
