I've had these for several months, now. The sound quality is actually very nice. Comfort is low. Your ears will be in pain after 15 to 20 minutes of use. I'm also very disappointed in the range. I've used these with several different bluetooth devices. In all cases I've had to be within a couple feet to avoid drop-outs. Any further than that and a simple head turn will drop signal. I've never seen BT headphones with such a short range.
