the etymotic silicone sleeves of these headphones at first delivered fantastic sound and real bass. while the quality was really decent. the sleeves are too soft and like to pull out easily , the cord also transmits sound like a train (running on the treadmill gave me a headache), and the white plastic gets dirty fast.if that wasnt enough to deter, ive had them for a month, and then for no reason the left earbud just ceased to work. im going to spend a little more money and get the sony mdr.
