These sounded great for about three uses. Then the fourth time I used them, after owning them for a little over a week, the left side dropped out as described in other reviews. Unfortunately these were a gift from my wife, so I didn't get the benefit of these reviews until after the fact. Very disappointing. Dog Funk of course has a great return policy in general, but having to pay for shipping to return these defective buds feels like a bit of a ripoff.
