I bought for my husband he like it a lot and the fact that he will lose them because they are attached to his keys. probably not. There are no steel bones in this thing. I highly recommend these headphones to anyone looking for excellent, balanced sound with a really good microphone. It clearly states, (Press and hold Mode button to turn the RGB on/off. There is also a Carbiner clip attached to the case, another nice touch. I have to return one and dared to buy another even I love the style and the quality. A friend have the same bike rack, seems to be perfect for our jeeps. They are so soft & super cute too! The settings you select through Brightness key + numbers 1-5 and 0 should save through a cold boot.
