Title: Sennheiser in-hear headphones stay in my ears!
Review: I've always had a problem finding in-ear headphones that actually stay in my ears. Other headphones are too big and fall out easily. These Sennheiser MX-400 must be a bit smaller than normal earphones because these ones fit and stay in perfectly. They are the only kind I buy now. And they sound great for an inexpensive headphone.
