I've had both the first gen and second gen of this product as they worked so well for blocking out my snoring husband that I've almost become reliant on them for sleeping. However from both sets I begin to start having problems with battery life after about 6 months of constant use and then only have a 2 year life span at best for both with the battery problems just becoming worse across that time. At the beginning battery life is a good 8-9 hours overnight by the end of the 2 years I'm lucky if I don't spend 15 mins just trying to connect it to get it working and then them dying in a few hours after that through the night. I would still recommend this product however I think the price should be decreased given it's life span for use.
