Title: Unusable after three months
Review: After I'd used mine regularly but not constantly for about three months, it developed a high-pitched whine that hurt my ears and gave me a headache. It was also annoying that there was no light to remind me to turn the switch off and stop draining the battery, but that's probably typical of this kind of product. I like the size and shape of it, and the sound quality was adequate for my needs (listening to podcasts) but it just didn't last.
