So I just got the new waterproof walkman - nwz-w273. I've been loving using it jogging and working out, but when I get into the pool, it doesn't seem quite right. It's ok when there's a completely tight seal between the earbuds and my ears, but when even a tiny bit of water seeps past the earbud, the plastic part of the player fills up with water, presumably through the earhole, and no sound comes out of that side. To fix it I have to completely shake all the water out of the walkman and leave it to dry. So my question is, is this normal? Do I have to keep my ears tightly plugged at all times, or is it my walkman's fault for having a leak? Should I send it back as faulty and get a new one?
