Summary: Not sure if mine was defective or if this is expected quality of these earphones but I received a blown piece and sounded bad. On the plus side the right ear sounded pretty good - high bass. I couldnt quite get used to the noise isolating feature - feels like it puts my ears in a vacuum.
Summary: After a few uses, the left earbud started to be scratchy and eventually stopped working completely. These earbuds come with three sizes of inserts that go in the ear, and the smallest size was still too big and the buds would frequently pop out. So disappointed, I hate buying things that are bad and that quickly just go to the landfill. In fact, I want my money back.
Summary: After receiving my second pair because the first did not work i was looking forward to finaly having a pair of head phones. What do you know these ones were defective too. The first pair both ears were blown and this time just the left ear. Thankfully they refunded me my money no problem.
