I waited to give a review till I had practical experience using them. The sound quality is very good as well as the comfort. I really like the ability of being able to control the volume at the headset unit. When I get about 30 feet away from the base unit through a few walls I get a bit of hiss which is tolerable.The battery life is excellent and even with rechargeable batteries. I have never run out of power wearing them all day.For me they have become an indispensible part of my computer use.The Ultimate Test of My ExperienceIf I ever manage to destroy these I would immediately repurchase another unit. For me the high price is worth the benefit I get from this product.A word of caution: I would say that the average user of headphones tends to listen at levels that are too loud. I'd start with a low volume level and turn up till the volume meets your listening needs. Just like diamonds, hearing damage is forever.
