I have had Reef flip flops before and liked them. High quality materials and construction. The drawers don?t move as smoothly as I would like, however, I don?t use them that much. Wireless subwoofer is great, no issue and lots of bass. So if the power start to die off but you need to listen to your music just plug into the usb port and bam your music is back in full force. These DT1990s have this fantastic ability to pull apart each track into the individual instruments, especially in rock music. I should have ordered a half size smaller. Havent used it to pullups or push-ups, but ab workouts are solid. The fleece inside is warm. In addition to getting the wrong item, the headphones I did receive werent good.
