Aiwa's Acoustic Plus earbuds actually do give the music a good acoustic sound with its air pocket inside the earbud itself. The outer air-filled pad makes things nice and comfortable, but the earbud overall might be a bit large for some ears. Granted, the air pad will contour to most ears, but using these for too long might lead to a bit of pain. On top of that, the air-filled pads are rather delicate. When one of them accidentally got pulled off, that earbud failed to respond entirely, and I had to buy a new pair.So overall, excellent sound for the price, but just be careful. That, and big ears help. ^_^
