Just trying them around the house. The holes in the columns did not align and the spotters wouldnt go through. Overall, these are very good headphones for the price point. Adds just enough cushion to your steps when walking on all the concrete surfaces we seem to have now at work and some people have concrete slabs they live on. My excitement didnt last long as the bike rack was very difficult to work with and two of our brand-new bikes got scratched up due to its poor design. I give stickers out w/ tips to essential workers. I would never had believed it but I love these. Its like a sleeveless dress with the drape attached to it at the top. They look great on my kitchen worktops and hold all the herbs and spices I use! Confort is very good.
