Ill be surprised if they dont break in 6 months. pairs easy and good Bluetooth connectivity. I plan to purchase another set of three to completely end the life cycle of any remaining moths. I always recommend! I am not sure if this would be able to be used with a bench though, I?ll have to see when we get our weight bench. Super comfortable and makes me feel cute and sexy. As to the size and look this is not that important to me. These shoes are comfy and stylish. Ive tested these with a whole range of music and its coped really well with everything thrown at it. The sound quality and noise cancelling are as good as, or better than, when she is using the phone without the headset.
