Excerpt: I settled on these around ear headphones. Sound quality is good, however you definitely will hear the right left speaker differences. Fits my head without fall backwards. Comfortable. Long cord is a benefit. For the money, this headset sounded better than the more expensive model and way better then the competitors in this price range. NO BATTERIES or CHARGING REQUIRED. These are not home speakers - so as a headset for general music listeners, iPod use - sound is good.
Summary: I purchased these after returning another brand of headphones. I found the returned pair lacked the clarity and quality of the Bose. The AE2i set is comfortable and you will notice the slightest of sounds when listening to a quality device/source. I use them with both my son's iPod and my Windows laptop with no regret. I listen to a lot of online music and some of those stations just do not stream at a high quality.
