I received this product as a gift and was very excited. As noted in other reviews, the comfort is lacking as the earbuds are too large for my ears.However, the bigest problem that I have is that the battery life is very very short. I have had the unit for a month and can only listen to music for 53 minutes and 32 seconds (yup, I timed it.) before it shuts off.In addition, you only get 500 charges out of the unit (per instruction manual). So I am expecting that the unit will be totally disfunctional within the next month or so.$80 for headphones that you can use for a month until they break is not a very good deal.
