I clung to it for a few moments and it didn?t budge and I weigh 200lbs. I bought this to take a QC25 four pole to two separate connections: mic out and audio in for PC gaming. If I had any complaints it would be 2 things. Put your worries or uncertainties aside and buy them. I ordered a size up (11-12) as advised and they fit fine. My needs are simple - a snug shoe that wont slip off my foot when Im walking. Turns out, not really. The strip itself is a little bit heavy, so you need to use your hands to prevent from detachment. If they were detailed they were lacking in bass. Would recommend for a home gym
