Mom?s headphones were frayed after much use of her wireless headset. Not only would I not recommend these earbuds, I would not recommend purchasing anything from Jlab. I do not flex in size. It is thicker than your average box retailer multipack of JMS or the Fruit brand. Love this item and would suggest it to anyone, especially at the price they are selling these ones for. I purchased 12 antiperspirant deodorants expecting to use them over a period of a year or more once my last 2 from previous order were used. Earbuds are never going to offer the full bass and clear highs of over-the-ear phones. I?ve been really pleasantly surprised! I did about a dozen 10-20 mile rides with no problems. It look more organization for my room instead my shoes were all over the floor.
