They work great for what I wanted, wireless headphones when I sleep. They have a plus, while inside, I can travel anywhere within 20 feet for so and still get a signal...Outside is another story. Due to all the other wireless frequencies and no possible reflection of the bluetooth signal, my phone (Moto RAZR Maxx) cannot put out a strong enough signal for this unit to pick up with no line of sight. My laptop has more than enough though, the sound is great outside give that it has a huge processor to sort the bluetooth and a battery far superior to the phone.But yeah. Works with phone and laptop great. Sound quality is great. Battery life is great. WOrks at the gym and doesnt fall off. Easy to sleep with (says a lot to the ergonomics).Probably not worth $80 though.
